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 that will 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.
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. • To combine open-systems volumes to create an open-systems volume (LU) larger than 2.8 TB. • When thin provisioning is not an option. For detailed information, see “Configuring expanded LU provisioning” (page 59).
Thin provisioning includes: • “Thin Provisioning concepts ” (page 17) • “Thin Provisioning” (page 19) Thin Provisioning Though basic or traditional provisioning strategies can be appropriate and useful in specific scenarios, they can be expensive to set up, awkward and time consuming to configure, difficult to monitor, and error prone when maintaining storage. Although Thin Provisioning requires some additional steps, it is a simpler alternative to the traditional provisioning methods.
each of them (see (page 48)). But then you set up a Thin Provisioning environment by creating one or more THP pools of physical storage space that are each a collection of some of these 3390-V LDEVs (THP pool volumes). This pool structure supports creation of 3390-A Thin Provisioning virtual volumes (THP V-VOLs), where 42-MB pages of data are randomly assigned on demand. For detailed information, see (page 69).
up to 1024 LDEVs may be assigned to a single pool, this represents a considerable amount of I/O power that is possibly made available to just a few THP volumes. Thin Provisioning work flow The following illustrates the Thin Provisioning workflow. Thin Provisioning After using Thin Provisioning software to virtualize LUs and pool storage into a thin provisioning strategy, the array now has all the elements in place to offer automatic self-optimizing storage tiers provided by Smart Tiers (Smart).
• Less storage management effort • More automation • Nondisruptive storage management • Reduced costs • Improved performance Tiers concept When not using Smart Tiers, data is allocated to only one kind of data drive (typically an expensive high-speed hard disk drive) without regard to the workload to the volumes because the volumes are configured with only one kind of data drive.
resource group can access only their assigned resources and cannot access other resources. Configuring resource groups prevents the risk of data leakage or data destruction by another storage administrator in another resource group. The resources such as LDEVs, parity groups, external volumes, ports, or host groups, can be assigned to a resource group. These resources can be combined to flexibly compose a virtual private storage system group.
Term Description You can set the percentage of THP-VOL capacity that can be created to the total capacity of the pool. This can help prevent THP-VOL blocking caused by a full pool.
If Smart Tiers is used, shared memory for Thin Provisioning and Smart Tiers is necessary. At least 24 GB of shared memory consisting of two sections is required. The memory capacity allocated to each part is as follows: • Basic part: 8 GB • Thin Provisioning: 8 GB • Smart Tiers: 8 GB The required shared memory is installed by your HP representative. Overall provisioning workflow Following is the overall workflow for setting up and provisioning volumes on the P9500 storage system. 1.
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 in 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 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. 4. Enter a resource group name in the Create Resource Groups window. Select resources to be assigned to the resource group as necessary, and then click Add. The resource group is added to Selected Resource Groups table. 5. 6. Click Finish. 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.

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 1,024 for other RAID levels Maximum number of volumes (normal and 65,280 Virtual LUN) per storage system Minimum size for one Virtual LUN volume OPEN-3, OPEN-8, OPEN-9,OPEN-E: 36,000 KB (+ control cylinders) OPEN-V: 48,000 KB (50 cylinders) Maximum size for one Virtual LUN volume See “CV capacity by emulation type for open systems” (page 42) Size increment 1 MB Disk location for Virtual LUN volumes Anywhere CV capacity by emulation type for open systems Emulation type* Minimum C
Additionally, if the data protection level is set to the Enhanced mode on a SATA drive parity group, you must calculate the entire capacity of all CVs in existence and the entire capacity of CVs in the Enhanced mode of the data protection level. When using RAID Manager, the specified size of CVs is created regardless of the capacity calculation.
boundary value depends on volume emulation types and RAID levels (see “Capacity of a slot” (page 47)) • The resulting entire capacity is expressed in blocks. To convert the resulting entire capacity into megabytes, divide this capacity by 2,048.
• 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 46)). 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 47)). • The CV capacity recognized by hosts is the same as the CV capacity calculated by the above formula.
user-specified-a-CV-capacity / 2 / capacity-of-a-slot where • capacity-of-a-slot is expressed in kilobytes. The capacity of a slot depends on volume emulation types (see “Capacity of a slot” (page 47)). • The resulting entire capacity is expressed in slots. To calculate the management area capacity: ceil(entire-capacity-of-a-CV(slots) / calculated-management-area-capacity) * boundary-value where • the value enclosed in ceil( ) must be rounded up to the nearest whole number.
Capacity of a slot Emulation type Capacity (KB) of a slot Other than OPEN-V 48 OPEN-V 256 Calculated management area capacities (SATA-E drive) Calculated management area capacities are expressed in slots. A SATA drive requires OPEN-V for open systems.
Creating an LDEV Use this procedure to create one or more internal or external logical volumes (LDEVs) in a selected storage system. You can create multiple LDEVs at once, for example, when you are setting up your storage system. After the storage system is set up, you can add LDEVs as needed. Before creating an LDEV in a selected storage system, free space may need to be created. Before volumes are deleted to create free space, remove the LU paths to the open-system volumes.
5. 6. 7. 6. Click View Physical Location. In the View Physical Location window, confirm where the selected free space is physically located, and then click Close. In the Select Free Spaces window, if the selected free spaces have no issues, click OK. Otherwise, if creating an external volume, select the external volume, and then do the following: 1. Click Select Free Spaces. 2. In the Select Free Spaces window, in the Available Free Spaces table, select the free space to be assigned to the volumes.
13. In the Create LDEVs window, in SSID, type four digits, in hexadecimal format (0004 to FEFF), for the SSID. 14. To confirm the created SSID, click View SSIDs to open the View SSIDs dialog box. 1. In the Create LDEVs window, in Initial SSID, click View SSIDs. In the SSIDs window, the SSIDs table shows the used SSIDs. 2. Click Close. 15. In the Create LDEVs window, from the Processor Blade list, select a processor blade to be used by the LDEVs.
Finding an LDEV SSID When creating volumes, the LDEV SSIDs must be specified. Use this procedure to determine the SSIDs in use in the storage system so you can specify the correct SSID. 1. In the Create LDEVs window, beside Initial SSID, click View SSIDs. 2. In the SSIDs window, review the list to confirm the LDEV SSIDs. The SSIDs table shows the SSIDs in use in the system. 3. Click Close. The Create LDEVs window opens. Editing an LDEV SSID Before registering an LDEV, you may need to edit the LDEV SSID. 1.
3. In the Confirm window, click Apply. The LDEV is removed from the registering task. If Go to tasks window for status is checked, the Tasks window opens. Blocking an LDEV Before formatting or shredding a registered LDEV, the LDEV must be blocked. This procedure blocks both internal and external volumes. 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.
For information about editing a registered external volume, see HP P9000 External Storage for Open and Mainframe Systems User Guide. 1. Select the LDEV to be edited. 2. Click Edit LDEVs. 3. In Edit LDEVs window, edit LDEV Name. 4. Click Finish. 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.
Formatting LDEVs If you initialize LDEVs that are being used, you will need to format the LDEVs.
Quick Format specifications Item Description Preparation for executing the The internal volume must be in blocked status. However, you do not need to create a Quick Format feature system disk. The number of parity groups that can undergo Quick Format Up to 36 parity groups can concurrently undergo Quick Format. There is no limit on the number of volumes that can undergo Quick Format.
Formatting all LDEVs in a parity group This procedure performs Normal formatting on the volume. When formatting all LDEVs in a parity group, you will need to: • Specify a parity group. • Format the LDEV. Before formatting all LDEVs in a parity group, make sure that all LDEVs under this parity group have been blocked. See “Blocking an LDEV” (page 52) for blocking an internal volume. See the HP P9000 External Storage for Open and Mainframe Systems User Guide for blocking an external volume. 1.
CAUTION: • If you change the processor blade ID for an LDEV, do this only when the I/O load is as low as possible. Do not change the processor blade ID when the I/O load is high (for example: during initial copy of Business Copy, Continuous Access Synchronous, or Continuous Access Journal). • After you change the processor ID for an LDEV, wait more than 30 minutes before you try to change it again for the same LDEV.
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. • Normal data cannot be stored on the system disk. • The bind mode of Cache Residency must not be set to the system disk. • I/O cannot be issued from the host of the open system because the system disk cannot be defined SCSI path. • The system disk should not be deleted or blocked while it is being used.
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 example The following figure shows an example of a LUSE configuration. The host sees the LUSE volume as one LDEV. The LUSE volume ID is the smallest LDEV ID. 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.
and, Continuous Access Journal, and External Storage Access Manager cannot be targets of LUSE operations (see “LUSE operations using a path-defined LDEV” (page 61)). • When combining a LUSE volume with another LUSE volume, the range of LDEVs should not be overlapped. For example, if you combine LDEV00, LDEV03 and LDEV05 into LUSE 1, LDEV02 and LDEV04 into LUSE 2, and LDEV06 and LDEV07 into LUSE3, you can also combine LUSE 1 and LUSE3.
Table 1 Host mode for defined paths by operating system (continued) Operating system Host mode AIX5.2 Not applicable AIX5.3 Not applicable 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.
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 P9000 Performance for Open and Mainframe Systems. 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.
1. To perform a LUSE operation on a volume that has a path definition, click OK. If a message appears asking whether you want to perform a LUSE operation that will affect more than one CLPR, go to step b. If this message does not appear, go to step 7. For detailed information about CLPRs, see the HP P9000 Performance for Open and Mainframe Systems. 2. 3. 7. 8. To perform a LUSE operation that will affect more than one CLPR, click OK. A confirmation dialog box opens. Then, go to step 7.
The unregistered LUSE volume is reset to the state before it was created, and the LUSE volumes or the LDEVs constituting the reset LUSE volume appear in the LUN Expansion window in the LDEV Detail table. Maintaining LUSE volumes Viewing LUSE volume details A LUSE volume is made up of multiple volumes (LDEVs). Use this procedure to view the details of the individual LDEVs that make up a LUSE volume. 1. In the Remote Web Console Main window, click Actions > Logical Device > LUN Expansion. 2. 3. 4. 5.
1. In the Remote Web Console Main window, click Actions > Logical Device >LUN Expansion. 2. 3. Click to change to Modify mode. Select a CU number from the LDEV Information tree. The LDEV Detail table lists all LDEVs in the selected CU. In the LUN Expansion window, select a LUSE volume in the LDEV Detail table. Right-click the selected LUSE volume, and then select Release LUSE Volume.
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 using multiple storage system LDEVs.
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 - (4116 + 336). Total Number of pages = Σ(floor(floor(pool-VOL number of blocks ÷ 512) ÷ 168)) for each pool-VOL. floor( ): Truncates the value calculated from the formula in parentheses after the decimal point.
Pool-VOL requirements Pool-VOLs make up a THP-pool. Items Requirements Volume type Logical volume (LDEV) For best performance, pool-VOLs for a pool should not share a parity group with other volumes. Pool-VOLs cannot be used for any other purpose.
Items Requirements Therefore, if different drive types are registered in the same pool, ensure that the I/O performance is the same for each drive. • Unless intentionally transitioning between SATA drive types, a SATA-E volume and a SATA-W/V volume should not coexist in a pool. RAID level for a Smart Tiers pool All RAID levels of pool-VOLs can be added. Pool-VOLs of RAID 5, RAID 6, RAID 1, and the external volume can coexist in a same pool.
Requirements for increasing THP V-VOL capacity You can increase THP V-VOL capacity up to 59.9 TB. To notify the host that the THP V-VOL capacity has been increased, make sure host mode option 40 is enabled. Processing differs as follows, depending on the value of host mode option 40: • When host mode option 40 is not enabled, the host will not be notified that the THP V-VOL capacity has been increased.
The following table shows the effects of some combinations of operating system and file system capacity. For more information, contact your HP representative. OS File System Metadata Writing Pool Capacity Consumed Windows Server 2003 and Windows Server 2008* NTFS Writes metadata to first block. Small (one page) Linux XFS Writes metadata in Allocation Group Size intervals. Depends upon allocation group size.
Using Thin Provisioning or Smart Tiers with other P9500 products Interoperability of THP V-VOLs and pool-VOLs THP V-VOLs and pool-VOLs can be used in conjunction with other P9500 products. The following table lists the operations that are permitted and not permitted. Product name (Guide name) Permitted Cache Residency (HP P9000 Not applicable Performance for Open and Mainframe Systems User Guide) Snapshot (HP P9000 Snapshot User Guide) Not permitted Performing operations on THP pool-VOLs or THP V-VOLs.
Product name (Guide name) Permitted Not permitted Business Copy (HP P9000 Business Copy User Guide) Using a THP V-VOL as a Business Copy P-VOL or S-VOL. • Using a pool-VOL as a Business Copy P-VOL or S-VOL. • Increasing the capacity of a THP V-VOL used by Business Copy. • Reclaiming zeropages of V-VOL used byBusiness Copy. Continuous Access Synchronous (HP P9000 Continuous Access Synchronous User Guide) Using a THP V-VOL as a Continuous Access Synchronous P-VOL or S-VOL.
Figure 1 Using Thin Provisioning and Continuous Access Synchronous Continuous Access Synchronous P-VOL Continuous Access Synchronous S-VOL Explanation THP V-VOLs THP V-VOLs Supported. THP V-VOLs Normal (ordinary) volumes Supported. Normal (ordinary) volumes THP V-VOLs Supported. Note, however, that this combination consumes the same amount of pool capacity as the original normal volume (P-VOL). You cannot specify a Thin Provisioning pool-VOL as a Continuous Access Synchronous P-VOL and S-VOL.
The following table lists the interaction when the Business Copy P-VOL and S-VOL are also THP V-VOLs. Figure 3 Using Thin Provisioning and Business Copy Business Copy P-VOL Business Copy S-VOL Explanation THP V-VOLs THP V-VOLs Supported. THP V-VOLs Normal (ordinary) volumes Supported. The Quick Restore function is unavailable. Normal (ordinary) volumes THP V-VOLs Supported. Note, however, that this combination consumes the same amount of pool capacity as the normal volume.
Resource Partition See “Resource group rules, restrictions, and guidelines” (page 28) for the conditions of resources that are necessary in the operation of other HP software and the precautions required when using Resource Partition. 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 Hitachi Data Systems representative.
CAUTION: If you delete a pool, its pool-VOLs (LDEVs) will be blocked. Blocked volumes should be formatted before use. CAUTION: If the V-VOL data is migrated through the host, the unallocated area of the volume is also copied. At this time, the used capacity of the pool increases after the data migration, because the unallocated area before the data migration becomes the allocated area by the write processing during the migration.
Categories of data may be based on levels of protection needed, performance requirements, frequency of use, and other considerations. Using different types of storage tiers helps reduce storage costs and improve performance. Because assigning data to particular media may be an ongoing and complex activity, Smart Tiers software automatically manages the process based on user-defined policies.
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. Using a 24-hour monitoring cycle, you can specify the times of day to start and stop performance monitoring. The 24-hour monitoring cycle does not have to start at midnight. Tier relocation begins at the end of each cycle. For more information, see (page 298).
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 insufficent for the allocation, the pages are allocated to the nearest lower tier.
Monitoring mode settings (see (page 92)) of Period or Continuous influences the values shown on the performance graph. Period mode will report the most recent completed monitor cycle I/O data on the performance graph. Continuous mode will report a weighted average of I/O data that uses recent monitor cycle data, along with historical data on the performance graph. 4. Determine the tier range values The page is allocated to the appropriate tier according to performance monitoring information.
If the performance utilization percent shows 100%, this indicates that the target I/O load to a tier is beyond the forcasted 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.
• While the pool-VOL is being deleted, tier relocation is not performed. After the pool-VOL deletion is completed, tier relocation starts. • 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.
Collected monitoring information is discarded The monitor information statuses are valid (VAL), invalid (INV), and calculating (PND) (see (page 90)). The recent monitoring information that is in valid or calculating status is discarded under any of the following conditions: • When a pool-VOL is added (in the case of an increasing the number of tiers) or deleted. • The Auto LUN operation is performed. Collection of the monitoring information is discarded only for the corresponding volumes.
tier. The buffer space for tier relocation is 2% in all tiers. The following illustrates the workflow of new page assignment. Figure 5 Workflow of a new page assignment NOTE: If you specify the new page assignment tier to THP V-VOL, the tier to which a new page is assigned can be specified. In the default setting, a new page is assigned from the middle tier and you can specify the tier to which the new page is assigned. The default setting is a new page assigned from the middle tier.
• Required capacity of cache memory for Smart Tiers: 4 GB • Therefore, in this example 40 GB of capacity of cache memory is required. Note that cache memory is installed in pairs. Therefore, actual capacity is twice the cache memory capacity. For example, if required controlling information is 8 GB, then actual installed capacity is 16 GB. To decrease the capacity of the cache memory for Smart Tiers, you have to remove Smart Tiers.
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.
• ◦ Uncompleted (n% relocated): The tier relocation is suspended at the indicated percentage progression. ◦ -: The pool is not a Smart Tiers or Smart Tiers Z pool. Relocation Priority on (page 282) and (page 327). Displays the relocation priority. • ◦ Prioritized: The priority is set to V-VOL. ◦ Blank: The priority is not set to V-VOL. ◦ -: V-VOL is not the Smart Tiers V-VOL or the tier relocation function is disabled. Performance Graph on (page 318).
Viewing monitor and tier relocation information: If the raidcom get thp_pool command is executed with the -key opt option specified, the monitoring information and tier relocation information are displayed. For details about the raidcom get thp_pool command, see HP P9000 RAID Manager Reference Guide. Items are displayed as follows: • STS This item displays the operational status of the performance monitor and the tier relocation. • ◦ STP: The performance monitor and the tier relocation are stopped.
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.
Notes on performing monitoring • You can collect a new cycle of monitoring data while performing relocation. • After monitoring stops, the tier range is automatically calculated. • The latest available monitoring information, collected just before the relocation is performed, is used for relocation processing. • When relocation is performed, the status of the monitor information must be valid (VAL).
For example, if you set the tiering policy level on a V-VOL(THP V-VOL) to a tier with a high I/O speed, the data is always stored on the high-speed tier when relocating tiers. Therefore, when you use that V-VOL(THP V-VOL), regardless of the actual quantity of the I/O load, you can always get high-speed responses (see (page 95)). You can set the tiering policy level to one of six tiering levels (see (page 95)). You can designate a tiering level or multiple tiering policies when creating the THP V-VOL.
levels can coexist in one pool. If you specify the level of the tiering policy, THP V-VOLs to which the same policy is set are grouped. • All is the default tiering level. In this case, data is stored to all of the tiers. • When a tier is added to the pool after setting the tiering level on a THP V-VOL, the THP V-VOL is relocated according to the new tier lineup. For example, if you set the tiering policy to level 5, the data is always allocated to the tier of the low I/O speed.
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 level selected Number of tiers in pool with performance 1 tier graph 2 tiers 3 tiers All In the performance graph, you can display a frequency distribution of a THP V-VOL assigned to any tiering policy.
Reserving tier capacity when setting a tiering policy If you set the tiering level 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-limit-performance-of-the-tier ÷ the-number-of-pages-in-the-tier The THP-VOL without a tiering level setting uses the unreserved area in the pool.
Example of reserving tier capacity The reservation priority depends on the level of tiering policy. The following figure illustrates the reservation priority. Tiers are reserved in order of priority from (1) to (7) in the figure. If the pool-VOL capacity is deficient when you reserve a tier, the nearest tier of your specified tier is allocated. If you specify two tiers like level 2 or level 4 of the tiering policy, first of all the upper tier is reserved.
Notes on setting tiering level • If Auto is set as the execution mode, tier relocation is performed based on the monitoring cycle. Therefore, when the tiering level setting is changed, tier relocation will automatically implement the tiering policy at the end of the current monitoring cycle (see Example 1 in (page 103). • If Manual is set as the execution mode, you must manually perform monitoring, issue a monitor stop, and then start relocation (see Example 2, Case 1, in (page 103)).
• ◦ For level 4, when tier 2 is full, the pages are allocated to tier 3. If tier 3 is full, the pages are allocated to tier 1. ◦ For level 5, when tier 3 is full, the pages are allocated to tier 2. If tier 2 is full, the unallocated pages are allocated to tier 1. If I/Os occur that exceed the I/O performance of the tier: ◦ If the tiering level on the THP V-VOL is set to all tiers, the tier range is considered and the tier capacity and the limit performance are allocated.
Tiering level of the tiering policy When specifying High When specifying Middle When specifying Low Note 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. Level 2 From tier 1, 2, to 3. From tier 1, 2, to 3. From tier 2, 1, to 3.
Rebalancing the usage level among pool-VOLs The usage level among pool-VOLs is rebalanced automatically so that the page usage ratio is averaged across pool-VOLs. Therefore, the loads of pool-VOLs are distributed. The usage level among pool-VOLs is automatically rebalanced in the following cases: • Expanding pool-VOLs • Shrinking pool-VOLs • Reclaiming zero pages Performance of the host I/O may decrease due to movement of the existing data.

Working with pools About pools Thin Provisioning requires the use of pools. A pool consists of more than one pool-VOL. A storage system supports up to 128 pools, each of which can contain up to 1024 pool-VOLs and 63,232 THP V-VOLs per pool. The pool for Thin Provisioning or Snapshot cannot be used in conjunction with other pools.
Pool status The following table describes the pool status that appears in Remote Web Console. The status indicates that a SIM code may have been issued that needs to be resolved. See “SIM reference codes” (page 129)for SIM code details. The THP V-VOL status remains normal even though the pool status may be something other than normal. Status Explanation SIM code* Normal Normal status. None Warning A pool-VOL in the pool is blocked. If the pool-VOL is blocked, SIM code 627XXX is reported.
When adding external volumes, Cache Mode of the volumes to be added must be all set to enable, or all set to disable.

A THP V-VOL is a volume in a thin provisioning storage system. It is the virtual volume from a THP pool. Data in the THP pool is used via a THP V-VOL. A THP V-VOL is a virtual LU to some hosts. 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.

Monitoring capacity and performance Monitoring pool capacity The storage system monitors the pool’s free capacity in accordance with threshold values defined when you create pools. If the pool capacity reaches the threshold values, warnings are issued as SIMs to Remote Web Console and SNMP traps to the open-systems host. See “Monitoring pool usage levels” (page 124) for more information.
pool allocation rates). You can then use this monitor information to tune the appropriate allocation. • ◦ Access frequency of THP V-VOL, read hit rates, and write hit rates (using Performance Monitor) ◦ Usage rates of property groups of pools (using Performance Monitor) ◦ Pool usage and elapsed time of pool usage (using Command View Advanced Edition). ◦ THP V-VOL usage (stored data rates) and elapsed time of pool usage (using Command View Advanced Edition).
Tuning with Smart Tiers If Smart Tiers is active on your storage system, you can monitor access frequency and performance use, and while Smart Tiers automatically relocates data to the most suitable data drive (tier). You can configure monitoring to be automatic or manual. In both cases, relocation of the data is automatically determined based on monitoring results. For details, see “Smart Tiers” (page 80) Thresholds Pool utilization thresholds Thin Provisioning monitors pool capacity using thresholds.
The following figure depicts setting the subscription limit of pool capacity. 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.
NOTE: For a pool where only one user-defined threshold is set, the system assigns the system threshold (fixed at 80%). The lower value of the single user-defined threshold and the fixed system threshold are set as the Warning Threshold; the higher value of the two is set as the Depletion Threshold. After one of the thresholds is changed, the system threshold cannot be enabled again. A SIM code is reported when the pool usage capacity exceeds the threshold changes. 6. 7. Click Finish.
SIM reference codes The following table provides information about SIM reference codes associated with Thin Provisioning. SIM Code (XXX = hexadecimal pool number) Event Thresholds or Values 620XXX Pool usage level exceeded the Warning Threshold 1% to 100% (in 1% increments).
◦ SIM 625000 In all pools in the storage system, if every THP pool’s usage level falls below the higher of of two effective thresholds, SIM is automatically completed. ◦ SIM 626XXX If the THP pool number XXX, usage level falls below both of the two effective thresholds, SIM is automatically completed. Manually completing a SIM Some SIMs must be manually completed to clear them from the system. After the trouble that caused the SIM is solved, you can manually complete the SIM.

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

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 the 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.

The WWN is a unique identifier for a host bus adapter in an open-system host, consisting of 16 hexadecimal digits. The following topics describe how to find the WWN of a host on different operating systems. It is best to make a record of the WWNs of the hosts in your storage system, because you will need to enter these WWNs in LUN Manager dialog boxes to specify the hosts used in your storage system.
The following is an example of finding a WWN on Oracle Solaris. # dmesg |grep Fibre <- Enter the dmesg command. : fcaw1: JNI Fibre Channel Adapter model FCW fcaw1: Fibre Channel WWN: 200000e0694011a4 <- Record the WWN. fcaw2: JNI Fibre Channel Adapter model FCW fcaw2: Fibre Channel WWN: 200000e06940121e <- Record the WWN. # Finding a WWN on AIX, IRIX, or Sequent To find the WWN in an IBM AIX, SGI Irix, or Sequent environment, use the fabric switch that is connected to the host.

10. Confirm the settings and enter the task name in the Task Name box. A task name can consist of up to 32 ASCII characters (letters, numerals, and symbols). Task names are case-sensitive. (date) - (task name) is input by default. 11. Click Apply in the Confirm window. If the Go to tasks window for status check box is selected, the Tasks window appears. Configuring LU paths When provisioning your storage system, and after configuring ports, hosts, and host groups, you must configure fibre channel LU paths.
Setting a UUID You can set an arbitrary ID to identify a logical volume from the host using LUN Manager with host mode option 33 on. This ID is called the UUID (user-definable LUN identifier). Note the following when setting UUID: • When host mode 05 OpenVMS is used, and if host mode option 33 is set to ON, LUs that do not have a UUID setting will be inaccessible. • When host mode 05 OpenVMS is used, and if host mode option 33 is set to OFF, LUs that have a UUID setting will be inaccessible.
Correspondence table for defining devices When configuring the storage system, you will need definition information about devices set by LUN Manager, for example, LUs, LDKC:CU:LDEV, or UUID. A correspondence table similar to the example below is useful and recommended when collecting this information. Port LU LDKC:CU:LDEV UUID OpenVMS device file name BR 0000 00:00:30 148 $1$dga148 BR 0001 00:00:31 149 $1$dga149 . . . . . . . . . . . . . . .

Information about LU paths associated with the selected host group appears. 5. 6. 7. On the menu bar, click Actions, Ports/Hosts Groups, and then View Host-Reserved LUNs. Or, select View Host-Reserved LUNs from the lower right of the window. The Host-Reserved LUNs window opens.
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. If you use the LUN Manager window to view a list of host groups in a port, host group 0, indicated by 00, usually appears at the top of the list.
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. When registering hosts in multiple host groups, you must enable LUN security (set the switch to ON). When you change LUN security from OFF to ON, you must specify the WWN of the host bus adapter.
The following topics provide information for managing user authentication on host groups, fibre channel ports, and fabric switches: • “User authentication” (page 172) • “Fibre channel authentication” (page 178) • “Fibre channel port authentication” (page 182) • “Setting fibre channel port authentication” (page 182)) • “Registering user information on a fibre channel port” (page 182)) • “Registering user information on a fabric switch” (page 183)) • “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.

Initializing host group 0 Use this procedure to set host group 0 (zero) to its initial state. This removes all the WWNs from host group 0 and also removes all the LU paths related to host group 0. This procedure also changes the host mode of host group 0 to Standard and initializes the host group name. For example, if you initialize host group 0 for the port CL1-A, the name of host group 0 will change to 1A-G00. Procedure 31 To initialize host group 0 1. Click Ports/Host Groups in the Storage Systems tree.
Deleting a host group Use LUN Manager to delete a host group. If host group 0 (zero) is deleted, all WWNs that belong to host group 0 are deleted and all LU paths that correspond to host group 0 are deleted. The host mode of host group 0 becomes Standard, and the host group name is initialized. To remove all the WWNs and LU paths from host group 0, you must initialize host group 0. For details, see “Initializing host group 0” (page 186). Procedure 33 To delete a host group 1.
