1 Introduction to provisioning Provisioning a storage system requires balancing the costs of the solution with the benefits that the solution provides. The following is an overview of provisioning strategies that you can implement on the P9500 to support your business. About provisioning Provisioning is a method of managing storage system devices or volumes.
The alternative is to use a host-based Logical Volume Manager (LVM) when the planned workloads require either more space or IOPS capacity than the individual physical volumes can provide. LVM is the disk management feature available on UNIX-based operating systems, including Linux, that manages their logical volumes.
When to use fixed-sized provisioning Fixed-sized provisioning is a best fit in the following scenarios: • When custom-sized provisioning is not supported. Custom-sized provisioning Custom-sized (or variable-sized) provisioning has more flexibility than fixed-sized provisioning and is the traditional storage-based volume management strategy typically used to organize storage space.
The following illustrates a simple expanded LU environment, where LDEVs are concatenated to form a LUSE volume. When to use custom-sized provisioning Use custom-sized provisioning when you want to manually control and monitor your storage resources and usage scenarios. When to use expanded-LU provisioning Expanded-LU provisioning is a best fit in the following scenarios: • In an open systems environment. • When you want to manually control and monitor your storage resources and usage scenarios.
Virtual LUN software is used to configure custom-sized provisioning. For detailed information, see “Configuring custom-sized provisioning” (page 44). Thin Provisioning Overview Thin provisioning is an approach to managing storage that maximizes physical storage capacity. Instead of reserving a fixed amount of storage for a volume, it simply assigns capacity from the available physical pool when data is actually written to disk.
Thin Provisioning enhances volume performance. This is an automatic result of how THP V-VOLs map capacity from individual THP pools. A pool is created using from one to 1024 LDEVs (pool volumes) of physical space. Each pool volume is sectioned into 42-MB pages. Each page is consecutively laid down on a number of RAID stripes from one pool volume. The pool’s 42-MB pool pages are assigned on demand to any of the THP V-VOLs that are connected to that pool.
Advantages Without Thin Provisioning With Thin Provisioning also increases storage use while reducing power and pooling requirements (total cost of ownership). Thin Provisioning advantage example To illustrate the merits of a Thin Provisioning environment, assume you have twelve LDEVs from 12 RAID 1 (2D+2D) array groups assigned to a THP pool. All 48 disks contribute their IOPS and throughput power to all THP volumes assigned to that pool.
as efficiently as possible, resulting in data that is accessed infrequently being placed on lower cost physical storage. • Automatically migrate small portions of host volumes to the most suitable data drive according to access frequency. Frequently accessed data is migrated to higher speed hard disk drives (for example, SSD). Infrequently accessed data is migrated to lower cost and lower speed hard disk drives (for example, SATA) to use the storage efficiently.
Data retention strategies After provisioning your system, you can assign access attributes to open-system volumes to protect the volume against read, write, and copy operations and to prevent users from configuring LU paths and command devices. Use the Data Retention to assign access attributes. For more information, see “Configuring access attributes” (page 164).
Term Description meta_resource A resource group in which additional resources (other than external volumes) and the resources existing before installing Resource Partition belong. page In Thin Provisioning, a page is 42 MB of continuous storage in a THP V-VOL that belongs to a THP-pool. pool A set of volumes that are reserved for storing Thin Provisioning, Fast Snap, or Snapshot write data.
Shared memory requirements If configuring thin provisioning, Thin Provisioning requires dedicated shared memory for the V-VOL management area. The V-VOL management area, which is automatically created when shared memory is added, is an area used to store information for associating pool-VOLs and THP V-VOLs. If Thin Provisioning is used, at least 16 GB of shared memory consisting of two sections is required.
Use the following formula to calculate the number of cache management devices that a THP V-VOL requires. In this formula, the user-specified capacity is the user area capacity of a V-VOL. ceil(user-specified capacity ÷ max-capacity-of-cache-management-device) The calculated value must be rounded up to the nearest whole number. Calculating the number of cache management devices required by a volume that is not a THP V-VOL One volume that is not a THP V-VOL requires one cache management device.
2 Configuring resource groups The Storage Administrator can divide a provisioned storage system into resource groups that allow managing the storage system as multiple virtual private storage systems. Configuring resource groups involves creating resource groups, moving storage system resources into the resource groups, and assigning resource groups to user groups. Resource groups can be set up on both open and mainframe systems. Resource Partition software is required.
The Security Administrator in the system division creates resource groups for each division in the storage system and assigns them to the respective divisions. The Storage Administrator in Division A can manage the resource groups for Division A, but cannot access the resource groups for Division B. In the same manner, the Storage Administrator in Division B can manage the resource groups for Division B, but cannot access the resource groups for Division A.
Example of resource groups not sharing ports If you assign ports to each resource group without sharing, performance can be maintained on a different port even if the bulk of I/O is issued from one side port. The following shows a system configuration example of an in-house system division providing the virtual private storage system for two divisions. Divisions A and B each use individual assigned ports and parity groups. In this example, they do not share a port.
After the above procedures, the Storage Administrators in A and B divisions can access the resource groups allocated to their own division. Meta_resource The meta_resource is a resource group comprised of additional resources (other than external volumes) and the resources that exist on the storage system before the Resource Partition is installed.
Resource group license requirements Use of Resource Partition on the P9500 storage system requires the following: • A license key on the Remote Web Console computer for Resource Partition software. For details about the license key or product installation, see the HP XP P9000 Remote Web Console User Guide. Resource group rules, restrictions, and guidelines Rules • The maximum number of resource groups that can be created on a storage system is 1023.
3. Enter a resource group name in the Create Resource Groups window. Select resources to be assigned to the resource group. 1. Click the appropriate buttons select parity groups, LDEVs, ports, or host groups. 2. Select resources from the available parity groups, LDEVs, ports, or host groups table. 3. Click Add. The selected resources move to the selected parity groups, LDEVs, ports, or host groups table. If the selected resource is removed, select the row and click Remove. 4. Click OK.
Removing resources from a resource group Before removing remove resources from a resource group, consider the following: • The resources removed from a resource group are returned to meta_resource. • Resources cannot be deleted from the meta_resource. • An LDEV that has the same pool ID or journal group ID cannot be partially removed. For example, if two LDEVs belong to the same pool, you cannot remove only LDEV1 from the resource group and leave only LDEV2.
Deleting a resource group You cannot delete the following: • The meta_resource. • A resource group that is assigned to a user group. • A resource group that has resources assigned to it. Procedure 5 To delete a resource group 1. 2. 3. 4. In the Remote Web Console main window, in the Storage Systems tree, click Administration, and then Resource Groups.

3 Configuring custom-sized provisioning Configuring custom-sized provisioning involves creating and configuring a customized volume (CV). A CV is a fixed-sized volume that is divided into arbitrary sizes. This provisioning strategy is suitable for use on both open and mainframe systems. Virtual LVI or Virtual LUN software is required to configure variable-sized provisioning.
Parameter Open system Maximum number of volumes 65,280 (normal and Virtual LVI/LUN) per storage system 65,280 Minimum size for one Virtual LVI/LUN volume 36,000 KB (+ control cylinders) 48,000 KB (50 cylinders) Maximum size for one Virtual LVI/LUN volume See “CV capacity by emulation type for See “CV capacity by emulation type for open systems” (page 45). open systems” (page 45).
Implemented LDEVs consume the entire capacity from the parity group capacity. Therefore, even if the sum of user areas of multiple CVs and the user area of one CV are the same size, the remaining free space generated when multiple CVs are created may be smaller than the free space in the parity group when one CV is created.
• boundary-value is expressed in kilobytes. The boundary value depends on volume emulation types and RAID levels (see “Boundary values for RAID levels (Enhanced mode on SATA drives)” (page 50)). If the data protection level is set to the Enhanced mode on a SATA drive, the boundary value depends on volume emulation types and RAID levels (see “Capacity of a slot” (page 50)) • The resulting entire capacity is expressed in blocks.

Configuring volumes in a parity group For RAID 5 (7D+1P), RAID 6 (6D+2P), or RAID 6 (14D+2P) a maximum of 2,048 fixed-size volumes (FVs) and a certain amount of free space are available in one parity group. For other RAID levels, a maximum of 1,024 FVs and a certain amount of free space are available in one parity group. Each parity group has the same configuration, and is assigned the same FVs of the same size and RAID level.
in Total Selected Free Space in the Parity Group Selection section on the Create LDEVs wizard. Confirm the number of free spaces, and then create the LDEVs accordingly. For example, if you are creating LDEVs in parity group PG1-1 and it contains two free spaces, 2 appears in Total Selected Free Space. In this case, if you specify 1 in Number of LDEVs per Free Space, and continue to create the LDEV, two LDEVs are created because one LDEV is created for each free space.
7. In LDEV Capacity, type the amount of LDEV capacity to be created and select a capacity unit from the list. You can enter the capacity within the range of figures displayed below the text box. You can enter the number with 2 digits after decimal point. You can change the capacity unit from the list. 8. 9. In Number of LDEVs, type the number of LDEVs to be created. • For an internal volume, Number of LDEVs per Free Space appears. • For an external volume, Number of LDEVs per External Volume appears.
17. Click Add. The created LDEVs are added to the Selected LDEVs table. The Provisioning Type, System Type, Emulation Type, Parity Group Selection, LDEV Capacity, and Number of LDEVs per Free Space or the Number of LDEVs per External Volume fields must be set. If these required items are not registered, you cannot click Add. 18. If necessary, change the following LDEV settings: • Click Edit SSIDs to open the SSIDs window.
1. 2. 3. 4. 5. 6. 7. In the Create LDEVs window, in the Selected LDEVs table, click Edit SSIDs. In the Edit SSIDs window, review the SSIDs table showing the existing SSIDs and ones to be added. If you change the SSID, select the appropriate LDEV, and then click Change SSIDs. In the Change SSIDs window, type the new SSID, and then click OK. In the Edit SSIDs window, click OK. In the Create LDEVs window, click Finish. In the Confirm window, click Apply. The new SSID is registered.
You can block LDEVs from any of the following tabs: • LDEVs tab when selecting any parity group in Parity Groups. • LDEVs tab when selecting Logical Devices. • 1. Virtual Volumes tab when selecting any pool in Pool. In the Remote Web Console main window, in the Storage Systems tree, select the resource to view in the tab. Find the target LDEV in the table and confirm the LDEV status in the Status column. 2. 3. • If Blocked appears, the LDEV is blocked. You can skip the remaining steps.
5. In the Confirm window, confirm the settings, in Task Name type a unique name for this task or accept the default, and then click Apply. If Go to tasks window for status is checked, the Tasks window opens. Deleting an LDEV (converting to free space) You can convert one or more of the LDEVs on a selected parity group into free space by deleting the LDEVs.
Formatting LDEVs includes the following tasks: • “Formatting a specific LDEV” (page 60) • “Formatting all LDEVs in a parity group” (page 60) About formatting LDEVs The LDEV Format function, which includes Normal Format, and Quick Format. These functions format volumes, including external volumes. Before formatting volumes, ensure that the volumes are in blocked status. The following table lists which formatting functions can be used on which LDEV types.
Particularly in the following cases, the I/O load concentrated on specific components may decrease performance during quick format operations. • • In a configuration that satisfies both of these conditions, many quick format operations are started at the same time. ◦ The following comprise the minimum configuration of a module: CHA (CHannel Adapter) CPC (Cache Path Control adapter) DKA (DisK Adapter) ESW (PCI Express Path Switch) ◦ The number of modules is one or two.
Item Description groups that have not undergone but can undergo Quick Format, use the following formula: 36 - X - Y Where: X indicates the number of parity groups on which Quick Format is being performed. Y indicates the number of parity groups where all volumes are blocked during the Quick Format. Storage system is powered off The Quick Format operation resumes when power is turned back on.
3. In the Format LDEVs window, select the format type from the Format Type list, and then click Finish. In the Confirm window, click Next to go to the next operation. 4. Click Apply. If Go to tasks window for status is checked, the Tasks window opens. Assigning a processor blade Assigning a processor blade to a resource You can assign a processor blade to resources (logical devices, external volumes, and journal volumes). 1.
CAUTION: • Changes to the processor blade ID of an LDEV should be made during off-peak hours when the I/O load is as low as possible. Before and after changes are made, it is recommended that the cache write-pending rate (%) for all CLPRs is lower than 50%. Do not change the processor blade ID when the I/O load is high -- for example during an initial copy operation of Business Copy, Continuous Access Synchronous, or Continuous Access Journal.
System disk rules, restrictions, and guidelines Rules • The minimum size of the system disk should be 130 MB in order to accommodate audit log buffer information. • The LDKC:CU:LDEV number assigned to the system disk should be distinguishable from the one for a normal volume. • Use the Delete LDEVs function to delete the system disk. Restrictions • The system disk cannot be created on a THP-VOL. • A system disk cannot be used for any other function or connected to a port.
4 Configuring expanded LU provisioning Configuring expanded LU provisioning involves combining several smaller LDEVs into an expanded logical unit volume to make a LUSE (logical unit size expansion) volume that is larger than the standard 2.8 TB. A LUSE volume is a set of LDEVs defined to one or more hosts as a single data storage unit. A LUSE volume is a concatenation of two to 36 LDEVs (up to 60-TB limit) that are presented to a host as a single LU. This provisioning strategy is for use on open systems.
LUSE configuration rules, restrictions, and guidelines Rules • Open volumes (OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V) are supported. • The number of LDEVs combined into a LUSE volume must be within the range 2 to 36. The number of expanded LUs (LDEVs) should not exceed 36, even if the LUSE volume contains another LUSE volume. • The emulation type of the LDEVs combined into a LUSE volume must be the same. • LDEVs that are to be combined into LUSE volumes must not be reserved for Auto LUN.
• Combining command devices into a LUSE volume is not supported. • Combining internal volumes, external volumes, and virtual volumes (V-VOLs) is not supported. • The host mode must be neither 0C[Windows] or 01[VMware]. • LDEVs are not pool-VOLs. • LDEVs are not JNL VOLs. • LDEVs are not system volumes. • LDEVs are not virtual volumes of Thin Provisioning (V-VOLs). • LDEVs are not quorum disks. Guidelines • Move or back up your data, or both, before creating a LUSE volume.
An LDEV can be used for LUSE operations using a path-defined LDEV with the following considerations: • For hosts other than Windows Server 2003, Windows Server 2008, VMware, AIX5.2 and AIX5.3, an LDEV cannot be used for LUSE operations using a path-defined LDEV. • Before performing LUSE operation to an LDEV with a path defined from a Windows Server 2003 or Windows Server 2008 host, ensure that the host mode of the Windows operating system is 2C (Windows Extension).
2. You can view the current LUSE configuration in the LUSE window: • The LDEV Information tree on the left provides an outline view of the CU numbers in a hierarchical structure. • The LDEV Detail table on the right provides detailed information for all open-system LDEVs in the selected CU. Viewing a concatenated parity group In the P9500 storage system, data can be written to an LDEV that extends across concatenated parity groups. Concatenation of parity groups provides faster access to data. 1. 2. 3.
Use one of these methods to create a LUSE volume in the LUN Expansion (LUSE) window: • Using the LDEV Detail table. • Using Select an LDEV list box in the LDEV Operation detail. • Using the Volume Count list box in the LDEV Operation detail. This way is recommended. Procedure 8 To create a LUSE volume using the Volume Count list box 1. 2. 3. In the Remote Web Console main window, click to change to Modify mode.
1. To perform a LUSE operation on a volume that has a path definition, click OK. If a message appears asking whether to perform a LUSE operation that will affect more than one cache logical partition (CLPR), go to step b. If the message does not appear, go to step 5. For detailed information about CLPRs, see the HP XP P9000 Cache Partition User Guide. 2. 3. 5. 6. To perform a LUSE operation that will affect more than one CLPR, click OK. A confirmation dialog box opens. Then, go to step 5.
7. 8. Click OK (or Cancel). The new settings that appear in the window in blue bold italics are LUSE volumes that have been created but not yet registered to the storage system until you click Apply. These LUSE volumes can be reset to the state before they were created (see “Resetting an unregistered LUSE volume” (page 71)). Click Apply, and then click OK. Resetting an unregistered LUSE volume When you create a LUSE volume, it is not registered in the storage system until you click Apply.
2. 3. 4. 5. Click to change to Modify mode. In the LUN Expansion window, select a LUSE volume in the LDEV Detail table. Right-click the selected LUSE volume, and then select LUSE Detail. In the LUSE Detail dialog box, review the details. After viewing this list, click Close.
7. 8. 9. Click OK. The new settings appear on the LDEV Detail table in blue bold italics but are not yet implemented. In the LUN Expansion window, click Apply. Click OK.
5 Configuring thin provisioning Thin provisioning technology allows you to allocate virtual storage capacity based on anticipated future capacity needs, using virtual volumes instead of physical disks. Thin provisioning is an optional provisioning strategy for both open and mainframe systems. Thin provisioning is implemented with Thin Provisioning by creating one or more Thin Provisioning pools (THP pools) of physical storage space.
Pool requirements A pool is a set of volumes reserved for storing Thin Provisioning write data. Items Requirements Pool capacity Calculate pool capacity using the following formula: The capacity of the pool (MB) = Total number of pages × 42 - 4200. 4200 in the formula is the management area size of the pool-VOL with System Area. Total Number of pages = Σ(floor(floor(pool-VOL number of blocks ÷ 512) ÷ 168)) for each pool-VOL.
Pool-VOL requirements Pool-VOLs make up a THP-pool. Items Requirements Volume type Logical volume (LDEV) While pool-VOLs can coexist with other volumes in the same parity group, for best performance: • pool-VOLs for a pool should not share a parity group with other volumes. • pool-VOLs should not be located on concatenated parity groups. Pool-VOLs cannot be used for any other purpose.
Items Requirements • Pool-VOLs of the same drive type with different RAID levels can coexist in the same pool. Note that HP recommends that you use the following configuration: ◦ If there are pool-VOLs of the same in a tier, unify the RAID levels. ◦ Although you can set four or more of hard disk drive types for pool-VOLs in the same pool, you should use three or fewer types.
Items Requirements Volume capacity Volume capacity from 46.87 MB to 59.9 TB per volume. • TB: 0.01 to 59.99 • GB: 0.04 to 61,439.99 • MB: 46.87 to 62,914,556.25 • Blocks: 96,000 to 128,849,011,200 However, if you use the volume as a P-VOL or S-VOL of Business Copy, Auto LUN V2, Continuous Access Synchronous, Continuous Access Journal, or External Storage Access Manager, the volume capacity must be 4 TB or less. Total maximum volume capacity of 5.0 PB per storage system. Path definition Available.
• The capacity to be added to the THP V-VOL must be specified within the range indicated below LDEV Capacity in the Expand V-VOLs window. • You cannot add capacity to the THP V-VOL while the pool related to the target THP V-VOL is in any one of the following statuses: ◦ Exceeding the subscription limit threshold ◦ In progress of pool capacity shrinking CAUTION: When increasing THP V-VOL capacity, do not perform the following operations.

Continuous Access Journal You can use Thin Provisioning or Smart Tiers in combination with Continuous Access Journal to replicate THP V-VOLs. Figure 2 Using Thin Provisioning or Smart Tiers and Continuous Access Journal The following table lists the supported Continuous Access Journal and Thin Provisioning or Smart Tiers volume combinations. Continuous Access Journal Continuous Access P-VOL Journal S-VOL Explanation THP V-VOLs THP V-VOLs Supported. THP V-VOLs Normal (ordinary) volumes Supported.
Business Copy P-VOL Business Copy S-VOL Explanation Note, however, that this combination consumes the same amount of pool capacity as the normal volume. The Quick Restore function is unavailable. Normal volumes include the internal volumes and external volumes that are mapped to the volumes of the external storage system using External Storage. For more information on external volumes, see the HP XP P9000 External Storage for Open and Mainframe Systems User Guide.
Thin Provisioning workflow Before you create a pool, you must create the V-VOL management area in shared memory. For information on adding shared memory, contact your HP Technical Support. The following diagram shows the steps for a Storage Administrator to follow in setting up Thin Provisioning on a storage system. Use Remote Web Console to create pools and THP V-VOLs. CAUTION: If you delete a pool, its pool-VOLs (LDEVs) will be blocked. Blocked volumes should be formatted before use.
Smart Tiers About tiered storage In a tiered storage environment, storage tiers can be configured to accommodate different categories of data. A tier is a group of storage media (pool volumes) in a THP pool. Tiers are determined by a single storage media type. A storage tier can be one type of data drive, including SSD, SAS, SATA, or external volumes. Media of high-speed performance make up the upper tiers. Media of low-speed response become the lower tiers.
In Auto execution mode, monitoring and relocation are continuous and automatically scheduled. In Manual execution mode, the following operations are initiated manually.
In both execution modes, relocation of data is automatically determined based on monitoring results. The settings for these execution modes can be changed nondisruptively while the pool is in use.
• Auto execution mode Auto execution mode performs monitoring and tier relocation based on information collected by monitoring at a specified constant frequency: from 0.5, 1, 2, 4, or 8 hours. All Auto execution mode cycle frequencies have a starting point at midnight (00:00). For example, if you select a 1 hour monitoring period, the starting times would be 00:00, 01:00, 02:00, 03:00, and so on.
In auto execution mode, the collection of monitoring data and tier relocation operations are performed in parallel in the next cycle. Data from these parallel processes are stored in two separate fields. • Data while monitoring is in progress in the next cycle. • Fixed monitoring information used in tier reliocation.
• Manual execution mode You can start and stop performance monitoring and tier relocation at any time. You should keep the duration of performance monitoring to less than 7 days (168 hours). If performance monitoring exceeds 7 days, then monitoring stops automatically. Manual execution mode starts and ends monitoring and relocation at the time the command is issued from Remote Web Console or RAID Manager.
Case 2: When tier relocation is performed with the first collection of monitoring information, the second collection of monitoring information can be performed. However, the third collection cannot be started. Because only two fields are used store collected monitoring information, the third collection cannot be overwritten. In that case, the third collection of the monitoring information is started after the first tier relocation is stopped or tier relocation has completed.
Figure 8 Third collection of monitoring information while tier relocation is performed When Smart Tiers is configured for automatic operations, the monitoring feature will be enabled and the time period for monitoring is set for all or part of a 24-hour period. At the end of each monitoring period, the relocation task is performed automatically. Tier relocation flow The following shows the flow of allocating new pages and migrating them to the appropriate tier.
1. Allocate pages and map them to THP V-VOLs Pages are allocated and mapped to THP V-VOLs on an on-demand basis. Page allocation occurs when a write is performed to an area of any THP V-VOL that does not already have a page mapped to that location. Normally, a free page is selected for allocation from an upper tier with a free page. If the capacity of the upper tier is insufficient for the allocation, the pages are allocated to the nearest lower tier.
If the performance utilization percent shows 100%, this indicates that the target I/O load to a tier is beyond the forecasted limit performance value. CAUTION: The limit performance value is proportional to the capacity of the pool volumes used in the tier. The total capacity of the parity group should be used for a pool to further improve the limit performance. 2. Determine the tier delta values The tier range values are set as the lower limit boundary of each tier.
• Frequency distribution is unavailable when there is no data provided by performance monitoring. • While the frequency distribution graph is being created or the tier range values are being calculated, the frequency distribution graph is not available. The time required for determining the tier range values varies depending on the number of THP V-VOLs and total capacity. The maximum time is about 20 minutes.
Monitoring information or execution conditions Status of data collection in progress Status of fixed monitoring information used in tier relocation S-VOLs used when initial copies of Continuous Access Synchronous or Continuous Access Journal are performed. Monitoring information is continuously collected continuously, but the monitoring of the volumes is reset.4 No effect on the fixed Continued. monitoring information.
Monitoring information or execution conditions Status of data collection in progress Status of fixed monitoring information used in tier relocation Tier relocation operations Solutions 1. If the version of the DKCMAIN program is earlier than 70-06-0X-XX/XX, tier relocation continues. 2. The execution mode is Auto or the script is written in manual execution mode, information is monitored again and tiers are relocated automatically. 3. The volume is monitored at the time of the next execution cycle. 4.
You can set the External LDEV Tier Rank when creating the pool, changing the pool capacity, or setting the Edit External LDEV Tier Rank window. The following table explains the performance priority (from the top) of hard disk drives. Priority Hard disk drive type 1 SSD 2 SAS 15K rpm 3 SAS 10K rpm 4 SAS 7.2K rpm 5 SATA 6 External volume* (High) 7 External volume* (Middle) 8 External volume* (Low) *Displays as External Storage in the Drive Type/RPM.
If the relocation cycle’s duration is not long enough for the allocation moves to all complete, then the amount of tier capacity used may not fully represent the desired target levels. Subsequent relocations should eventually reach the target levels.
Notes on performing monitoring • You can collect the monitoring data even while performing the relocation. • After stopping the monitoring, the tier range is automatically calculated. • The latest available monitoring information, which is collected just before the relocation is performed, is used for the relocation processing. • When the relocation is performed, the status of the monitor information must be valid.
For details about the relocation progress rate, check the tier relocation log. For more information about the table item for the tier relocation log file, see “Tier relocation log file contents” (page 107). • Pool Management Task (Status/Progress) on “View Pool Management Status window” (page 350). Displays the status of the pool management task being performed, each V-VOL progress ratio in the pool and its average. ◦ Waiting for Relocation: The tier relocation process is being waited.

0 to 99: Shows one of the following statuses. ◦ When the value of STS is RLC or RLM: Relocation is in progress. ◦ When the value of STS is STP or MON: Relocation is suspended at the indicated percentage progression. 100: Shows if the relocation operation is not in progress, or the relocation is complete. Monitoring modes When you create or edit a pool, specify the Smart Tiers monitoring mode. The monitoring mode is either the period mode or the continuous mode.
Cautions when using monitoring modes • If Continuous mode is used, best practice is to collect monitoring information using the following execution modes: ◦ Auto execution mode ◦ Manual execution mode with collecting the periodic monitoring information by defining a script using RAID Manager If the Manual execution mode is used without scripts, the Continuous monitoring mode can be set.
Tier relocation log file contents The tier relocation log file is a tab-delimited file and contains the following information: Item Description Pool ID Displays the pool ID. Start Relocation Time Displays the time and date when the performing the relocation function starts. End Relocation Time Displays the time and date when the performing the relocation function ends. Result Displays the section where the relocation result is shown.
Tiering policy expansion In the current release, the tiering policy concept has been expanded to provide new options: • Custom policies. You can define up to 26 new policies (Level6(6) - Level31(31)) in addition to the existing six (All(0), Level1(1), Level2(2), Level3(3), Level4(4), and Level5(5)). See “Setting tiering policy on a THP V-VOL” (page 109). A custom policy can be set for a THP V-VOL when it is created and changed, if necessary, after creation. NOTE: Custom policies cannot be renamed.
The following figure shows an example of data allocation when setting the tiering policy to Level1(1) (see Level1(1) in “Tiering policy levels” (page 110)). In this case, pages in the THP V-VOL are relocated to tier 1, and are not relocated to other tiers. Setting tiering policy on a THP V-VOL The setting of a tiering policy for a THP V-VOL is optional. If one is not selected, the default is the All(0) tiering policy level. The available levels are listed in “Tiering policy levels” (page 110)).
Example of deleting a tier If a tier no longer has any pool-VOLs when you delete them, the tier is deleted from the pool. The following figure illustrates deleting a tier. For more information about tiering policy and groups, see “Tiering policy levels” (page 110). Tiering policy levels Tiering policy 1 tier pool 2 tier pool 3 tier pool Note All(0) Single Tier Both tiers All 3 tiers Default Tiering Policy Level1(1) Same as All(0) Tier 1 Tier 1 Data is located to the Top Tier.
The following table shows how tiering policy is shown in the performance graph. How the graph appears depends on the number of tiers set in a pool and tiering policy level selected when viewing the performance graph. Tiering policy selected with performance graph V-VOL displayed in the performance graph All(0) In the performance graph, you can display a frequency distribution of a THP V-VOL, set to all tiers.
Reserving tier capacity when setting a tiering policy If you set the tiering policy of a THP-VOL, the THP-VOL used capacity and the I/O performance limitation are reserved from the tier. The reserved limit performance per page is calculated as follows: The reserved limit performance per page = (The performance limit of the tier) ÷ (The number of pages in the tier). A THP-VOL without a tiering policy setting uses the unreserved area in the pool.
diagram below, tier 1 is reserved first. If the capacity of tier 1 is deficient at this point, tier 2 is reserved automatically. For details, see “Notes on tiering policy settings” (page 114). Tier reservation priority Tiering policy Reserved tier 1 Level1(1) Tier 1 2 Level3(3) Tier 2 3 Level5(5) Tier 3 From 4 to 29 From Level6(6) to Level31(31) The custom policy whose number is small is prioritized. Tier 1: From Level6(6) to Level31(31), each of the Tier1 Min values are reserved.
Notes on tiering policy settings • If Auto is set as the execution mode, tier relocation is performed based on the monitoring cycle. Therefore, when the tiering policy setting is changed, tier relocation will automatically implement the tiering policy at the end of the current monitoring cycle. See Example 1 in “Execution mode settings and tiering policy” (page 119).
Tiering Policy Allocation capacity considerations Allocation capacities in each tier. ◦ Tier1: The setting value(%) in Tier1 Min. ◦ Tier2: The value deducted Tier1 Max(%) and Tier3 Max(%) from 100(%). ◦ Tier3: The setting value(%) in Tier3 Min. Second phase: Tier range and I/O performance. Capacities deducted from the allocated capacities of the first phase from the total used capacity, are allocated to each tier.
Number Condition Order of new page allocation 1 T1 MIN = 100% Same as Level1(1) 2 T1 MAX = 0% Same as Level5(5) 3 T1 MAX > 0% Same as All(0) Tiering policy When specifying High When specifying Middle All From tier 1, 2, to 3. From tier 2, 3, to 1. From tier 3, 2, to 1. Specifying High, Middle or Low to the assignment sequence is effective. Level 1 From tier 1, 2, to 3. From tier 1, 2, to 3. From tier 1, 2, to 3. Assignment sequences when High, Middle, and Low are same.
example, three LDEVs are relocated in each period, but the number of LDEVs to relocate may change by the relocation cycle or the data size.
Tier of deleted pool-VOLs Order in which pages are allocated to tiers Description If there is no free space in Tier 1 and Tier 2, pages are allocated to Tier 3. Tier 3 Tier 3, Tier 2, and Tier 1 If there is free space in Tier 3, pages are allocated to Tier 3. If there is no free space in Tier 3, pages are allocated to Tier 2. If there is no free space in Tier 2 and Tier 3, pages are allocated to Tier 1. The following table describes page allocation in a 2-tier configuration.
• Reclaiming zero pages by the page releasing request of a host. For example, when the Write Same command is performed. • Performing tier relocations several times Performance of the host I/O may decrease due to movement of the existing data. If you do not want to automate balancing of the usage level of pool-VOLs, call HP Technical Support.

Pool-VOLs to which external volumes are mapped assigned to the Smart Tiers pool Using P9500 microcode 70-02-0x or later, you can assign pool-VOLs to which external volumes are mapped to the Smart Tiers pool. However, restrictions apply to the following cases. Pool type Version that pools were created Updated version What cannot be done Smart Tiers Prior to 70-02-0x 70-02-0x or later Pool-VOLs to which external volumes are mapped cannot be assigned to this pool.
On open systems, OPEN-V is the only supported emulation type on a THP V-VOL. You can define multiple THP V-VOLs and assign them to a Thin Provisioning pool. Relationship between a pool and THP V-VOLs Before you can use Thin Provisioning, a THP V-VOL and a pool are required. Thin Provisioning uses the pool volumes in a pool through the THP V-VOLs. The following figure shows the relationship between a pool and THP V-VOLs.

In the Selected LDEVs table in the Create LDEVs window, select an LDEV, and then click Change LDEV Settings. 2. In the Change LDEV Settings window, you can change the setting of LDEV Name, Initial LDEV ID, or Processor Blade. 3. 4. 5. • If you change LDEV Name, specify the prefix characters and the initial number for this LDEV.
You can provision a larger virtual capacity beyond the pool capacity by using THP V-VOLs of Thin Provisioning or Smart Tiers. However, when the pool’s free capacity is depleted, you can lose access to THP V-VOLs that require more pool capacity. For example, if the pool usage rate is 100% due to increased write operations, then I/O is not accepted and I/O will be stopped for a THP V-VOL that failed to receive needed pool capacity.
• ◦ THP V-VOL usage (stored data rates) and elapsed time of pool usage (using Command View Advanced Edition Suite). ◦ Smart Tiers performance monitoring of pool storage Possible tuning actions (without Smart Tiers). The following techniques using Business Copy or Tiered Storage Manager will move a THP V-VOL. ◦ The THP V-VOL is copied using Business Copy from a pool with an I/O bottleneck. For more information, see the HP XP P9000 Business Copy User Guide.
Thresholds Pool utilization thresholds Thin Provisioning monitors pool capacity using thresholds. A threshold is the proportion (%) of used capacity of the pool to the total pool capacity. Each pool has its own pool threshold values. • Warning Threshold: Set the value between 1% and 100%, in 1% increments. The default is 70%. • Depletion Threshold: Set the value between 1% and 100%, in 1% increments. The default is 80%.
Monitoring total THP-VOL subscription for a pool You can configure the Subscription Limit of total THP-VOL capacity to pool capacity. This prevents a new THP-VOL capacity that exceeds the configured subscription limit from being allocated and is associated to the pool. If you specify more than 100% as the Subscription Limit or the subscription limit is not set, you must monitor the free capacity of the pool because it is possible that writes to the THP-VOLs may exceed pool capacity.

the pool capacity process might fail. In this case, check the Tasks window to determine whether processing has abnormally ended. If the processing has ended abnormally, restore the cache memory, and then try decreasing the pool capacity again. NOTE: You cannot perform the following operations on a pool while the pool volume capacity is in the process of shrinking. Wait until shrinking completes or stop the shrinking process.
When the pool-VOL is deleted, the pages contained in the deleted pool-VOL transfer to another pool-VOL in the same tier. If the used capacity in the tier exceeds Rate of Free Space Newly Allocated to, the overflowing pages transfer to another tier. When pool-VOLs in the pool are empty, the appropriate tier is deleted. Deleting the pool-VOL stops tier relocation. The process resumes after the pool-VOL is deleted. Decreasing pool capacity 1.
• Changing the threshold. • Initializing the pool capacity. • Changing the external LDEV tier rank Notes on deleting a tier in a pool You cannot delete a pool-VOL under these conditions. • If the pool-VOL is deleted, the used capacity of the pool-VOL exceeds the pool threshold. • If the pool-VOL is deleted, the subscription rate of the total V-VOL capacity exceeds the subscription limit. • If the pool-VOL with system area has less than 4.2 GB of free space.

6 Configuring access attributes After provisioning your system, you can assign access attributes to open-system volumes to protect the volume against read, write, and copy operations and to prevent users from configuring LU paths and command devices. Data Retention software is required to assign access attributes to volumes. About access attributes Open-systems volumes, by default, are subject to read and write operations by open-systems hosts.
Access attributes and permitted operations Access Attribute Read Operations from Hosts Write Operations from Hosts Specified as P-VOL Specified as S-VOL Read/Write Yes Yes Yes Yes Read-only Yes No Depends on the replication No software Protect No No Depends on the replication No software Read/Write and S-VOL disable Yes Yes Yes No Access attribute restrictions Some restrictions apply when you use the following P9500 products or functions on a volume that has an access attribute assign

Procedure 15 To change an access attribute to read-only or protect 1. 2. Log on to Remote Web Console as a user with the Storage Administrator (Provisioning) role. In the Remote Web Console main window, click Actions > Other Function > Data Retention to open the Data Retention window. Figure 10 Data Retention window 3. 4. 5. 6. Click to change to Modify mode.
7. In the Term Setting dialog box, specify the retention term. During this period, the access attribute cannot be changed to read/write. You can enter the number of years and days, or select Unlimited. The retention term can be extended but cannot be shortened. • years: Specify the number of years within the range of 0 to 60. One year is counted as 365 days, whether the year is a leap year. • days: Specify the number of days within the range of 0 to 21900.
3. 4. 5. 6. Click to change to Modify mode. In the Data Retention window, verify which button appears beside Expiration Lock. • If Disable -> Enable appears, go to the next step. • If Enable -> Disable appears, expiration lock is already enabled. You do not need to follow the rest of this procedure because attempts to change access attribute to read/write are already prohibited. Click Disable -> Enable. A confirmation message appears. Click OK.
4. 5. 6. 7. In the Data Retention window, select an LDKC number in the LDKC list, select a group that the CU belongs in the CU Group list, and then click a CU in the tree. Select a volume where the Reserved column contains a hyphen. You may select multiple volumes. Right-click the selected volume or volumes, and then select Reserved > Set. Click Apply to apply the setting.
7 Managing logical volumes After provisioning your system, you can begin to manage open-system logical volumes. Managing logical volumes includes tasks such as configuring hosts and ports, configuring LU paths, setting LUN security on ports, and setting up fibre channel authentication. LUN Manager is required to manage logical volumes.
You can define paths between a single server host and multiple LUs. The figure shows that each of the two hosts in the host group hg-lnx can access the three LUs. You can also define paths between multiple server hosts and a single LU. The figure shows that the LU identified by the LDKC:CU:LDEV number 00:00:00 is accessible from the two hosts that belong to the hg-lnx host group. The figure also shows that the LUs associated with the hg-lnx host group are addressed by numbers 0000 to 0002.
Restrictions • You cannot define an LU path to volumes reserved by Auto LUN. For more information on Auto LUN, contact HP Technical Support. • You cannot define an LU path to journal volumes. • You cannot define an LU path to pool volumes. • You cannot define an LU path to system disk volumes. • When defining LU paths, you must not use RAID Manager and Remote Web Console at the same time.
Configuring fibre channel ports Setting the data transfer speed on a fibre channel port As system operation continues, you might notice that a large amount of data is transferred at some ports, but a small amount of data is transferred at other ports. You can optimize system performance on a fibre channel port by setting a faster data transfer speed on ports where a larger amount of data is transferred, and setting a slower data transfer speed on ports where a smaller amount of data is transferred.

You can connect multiple server hosts of different platforms to one port of your P9500 storage system. When configuring your storage system, you should group server hosts connected to the storage system by host groups. For example, if HP-UX hosts and Windows hosts are connected to a port, create one host group for HP-UX hosts and create another host group for Windows hosts. Then register HP-UX hosts to the corresponding host group and register Windows hosts to the other host group. NOTE: cluster.

5. In the LUN ID column, click the LUN to open the LUN Properties window. Releasing LUN reservation by host The following explains how to release forcibly a LUN reservation by a host. Prerequisites • You must have the Storage Administrator (system resource management) role to perform this task. CAUTION: If you perform the releasing a LUN reservation by a host, the host which is connected to LDEV by LUN path is affected. To release a LUN reservation by a host: 1.
hg-hpux host group can access only two LUs (00:02:01 and 00:02:02). The two hosts in the hg-solar host group can access only two LUs (00:01:05 and 00:01:06). Disabling LUN security Typically, you do not need to disable LUN security on ports. For example, if LUN security is disabled on a port, the connected hosts can access only the LUs associated with host group 0, and cannot access LUs associated with any other host group. Host group 0 is the only host group reserved, by default, for each port.
LUN security is disabled, by default, on each port. When you configure your storage system, you must enable LUN security on each port to which hosts are connected. Enabling LUN security on a port To protect mission-critical data in your storage system from illegal access, secure the logical volumes in the storage system. Use LUN Manager to secure LUs from illegal access by enabling LUN security on ports. By default, LUN security is disabled on each port.
The following topics provide information for managing user authentication on host groups, fibre channel ports, and fabric switches: • “User authentication” (page 193) • “Fibre channel authentication” (page 199) • “Fibre channel port authentication” (page 203) • “Setting fibre channel port authentication” (page 203)) • “Registering user information on a fibre channel port” (page 203)) • “Registering user information on a fabric switch” (page 204)) • “Clearing fabric switch user information” (pag
On a host group that performs authentication, register user information (group name, user name, and secret) of the hosts that are allowed to connect to the host group. A secret is a password used in CHAP authentication. When registering user information, you can also specify whether to enable or disable authentication on a host basis. On hosts, configure the operating system and fibre channel host bus adapter driver for authentication by host groups with CHAP.
The host group authenticates the user information sent from the host. If authentication of the host is successful, either of the following occurs: • When the host is configured for mutual authentication, authentication of the host group is performed. • When the host is not configured for mutual authentication, the host connects to the storage system. If the host is not configured for authentication by host groups with CHAP, the authentication fails and the host cannot connect to the storage system.
In the example, host group 1 performs authentication of hosts, and host group 2 does not. The user information of host A is registered on the host group 1, and the authentication setting is enabled. Therefore, if the authentication of the host is successful, host A can connect to the storage system (or, the processing goes on to the authentication of the host group). As a precondition of successful authentication, host A should be configured for authentication by host groups with CHAP .
Port settings and connection results The following table shows the relationships between host group settings and the connection results in authentication of hosts. Unless otherwise noted, connection results are as described regardless of whether the host is configured for authentication by ports with CHAP.
Authenticating fabric switches by ports (Cases A, B, and C) • If the user information of the fabric switch is registered on the port, and authentication of the fabric switch is enabled (Case A) Each port authenticates the fabric switch. If the authentication of the fabric switch ends successfully, either of the following actions occurs: ◦ When the fabric switch is configured for mutual authentication, processing continues to authentication of the port.
During authentication of hosts, the connection result is determined depending on the combination of the following port settings: • Setting of the port in the Port tree: enable ( • Whether the user information of the fabric switch that attempts to connect is registered on the port ) or disable ( ) Fabric switch settings and connection results The following table shows the relationship between the combinations of port settings and the connection results in authentication of fabric switches.
