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. Some provisioning methods are host-based, while others use existing storage system capabilities such as concatenated array groups.
When to use fixed-sized provisioning Fixed-sized provisioning is a best fit in the following scenarios: • Use fixed-size provisioning in cases where standard IBM 3390 volume sizes (3390-3, 3390-9, etc.) are required. 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.
Virtual LVI software is used to configure custom-sized provisioning. For detailed information, see “Configuring custom-sized provisioning” (page 34). 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.
LDEVs. Then, you can establish virtual THP volumes (THP V-VOLs) and connect them to the individual THP pools. In this way, capacity to support data can be randomly assigned on demand within the pool. THP V-VOLs are of a user-specified logical size without any corresponding physical space. Actual physical space (in 38-MB pool page units) is automatically assigned to a THP V-VOL from the connected THP pool as that volume’s logical space is written to over time.
Advantages Without Thin Provisioning Z efficiency of the data unused. I/O loads may concentrate on just a drive subset of the storage which might decrease performance. With Thin Provisioning Z bottlenecks in parity group performance. Configuring the volumes from multiple parity groups improves parity group performance. This also increases storage use while reducing power and pooling requirements (total cost of ownership).
high performance while reducing storage costs by using high cost disks such as SSDs 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).
When to use Smart Tiers Z Smart Tiers Z is the best fit in an environment in which Thin Provisioning Z is a good fit and datasets with different performance requirements share volumes. For detailed information, see “Configuring thin provisioning ” (page 54). Resource groups strategies A storage system can connect to multiple hosts and be shared by multiple divisions in a company or by multiple companies. Many storage administrators from different organizations can access the storage system.
Key terms The following are provisioning key terms: Term Description access attributes Security function used to control the access to a logical volume. Access attributes are assigned to each volume: read only, read/write, and protect. CV (variable volume) Customized Volume. A fixed volume that is divided into arbitrary sizes. expiration lock Security option used to allow or not allow changing of the access attribute on a volume. FV Abbreviation for fixed-sized volume.
• A Remote Web Console client computer. • A minimum of 1 pair of FICON CHAs. Shared memory requirements If configuring thin provisioning, Thin Provisioning Z 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 Z is used, at least 16 GB of shared memory consisting of two sections is required.
ceil(user-specified capacity ÷ max-capacity-of-defined-pool-volume) The calculated value must be rounded up to the nearest whole number. Calculating the number of pool volumes and LDEVs required by a volume that is not a THP V-VOL One volume that is not a THP V-VOL requires one LDEV. Viewing the number of pool volumes and LDEVs Click Actions and select View Management Resource Usage to display the View Management Resource Usage window. For details, see (page 19) and (page 241).
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.
• 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. Use the sort function to sort the LDEVs by pool ID or journal group ID, then select them and remove them all at once. • You must have Security Administrator (View & Modify) role to perform this task. Procedure 3 To remove resources from a resource group 1. 2. 3. 4.
2. 3. 4. Click one or more resource groups to delete in the Resource Groups tab. Click Delete Resource Groups. 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. Using Resource Partition and other P9500 products To use Resource Partition with other P9500 products, the resources that are required for the operation must satisfy specific conditions.
Operation name Condition All the volumes that are specified when creating a pool must belong to the same resource group. Edit pools Delete pools Pool-VOLs of the specified pool must be assigned to the Storage Administrator group permitted to manage them. Expand V-VOLs You can expand only the V-VOLs that are assigned to the Storage Administrator group permitted to manage them.
Operation name Condition Release pairs Set reserve attributes Remove reserve attributes The specified LDEVs must be assigned to the Storage Administrator group permitted to manage them. Continuous Access Synchronous Z The following table provides information about specific Continuous Access Synchronous Z conditions that must be observed when using Resource Partition. Operation name Condition Create pairs M-VOLs must be assigned to the Storage Administrator group permitted to manage them.
Operation name Condition Change journal options All the data volumes in the specified journals must be assigned to the Storage Administrator group permitted to manage them. Create pairs Journal volumes for pair volumes and P-VOLs must be assigned to the Storage Administrator group permitted to manage them. Initiator ports of logical paths to remote storage systems must be assigned to the Storage Administrator group permitted to manage them.
Operation name Condition Reconnect external storage systems All the external volumes belonging to the specified external storage system and all the LDEVs allocated to that external volumes must be assigned to the Storage Administrator group permitted to manage them. Disconnect external volumes The specified external volume and all the LDEVs allocated to the external volumes must be assigned to the Storage Administrator group permitted to manage them.
Operation name Condition When you create an internal or external volumes parity groups where the LDEV belongs and ID of the new LDEV must be assigned to the Storage Administrator group permitted to manage them. Delete LDEVs When deleting an internal or external volume, the deleted LDEV and parity groups where the LDEV belongs must be assigned to the Storage Administrator group permitted to manage them.
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 software is required to define variable-sized provisioning in a mainframe environment.
Parameter Mainframe system Maximum number of volumes (normal and 65,280 Virtual LVI per storage system Minimum size for one Virtual LVI volume 1 user cylinder (+ control cylinders) Maximum size for one Virtual LVI volume See “CV capacity by emulation type for mainframe systems” (page 35) Size increment 1 user cylinder CV capacity by emulation type for mainframe systems Emulation type Minimum CV capacity (cyl) Maximum CV capacity (cyl) Number of control cylinders (cyl) 3380-3 1 3,339 7 3380-3
Emulation type Minimum CV capacity (cyl) Maximum CV capacity (cyl) Number of control cylinders (cyl) to multiples of 1,113 cylinders. For instance, if 65,521 is specified, the value is changed to 65,667, which is 59 times 1,113 cylinders. 2. For 3390-A, for the Compatible FlashCopy SE volume, if you specify a value between 1 and 40,068 cylinders, the free space whose size is the sum of the specified value and 252 cylinders is required.
Calculating the size of a mainframe volume To calculate the entire capacity of a CV, use the following formulas. For the user-specified-CV-capacity, specify the capacity of the user area in a CV.
Calculating the size of a CV using Enhanced mode on SATA drives If the data protection level is set to Enhanced mode on a SATA drive, the entire capacity of a CV must be calculated based on the previously calculated entire capacity of a CV. The calculation methods vary depending on the unit for the capacity specified when creating the CV.
where • calculated-entire-capacity-of-a-CV(slots) means the entire capacity of a CV if the data protection level is set to the Enhanced mode on the SATA drive.
Emulation type Boundary value (KB) RAID 1 (2D+2D) RAID 5 (3D+1P) RAID 5 (7D+1P) RAID 6 (6D+2P) RAID 6 (14D+2P) • Boundary values are of external volumes are always one kilobyte, regardless of RAID levels. • Hyphen (-) indicates that the combination is not supported. Capacity of a slot Emulation type Capacity (KB) of a slot 3380-xx 48 3390-xx 58 Notes: • xx indicates one or more numbers or letters. • Slot capacity is expressed in kilobytes.
Create LDEV function Use the Create LDEV function to create a customized variable-sized volume. Use Virtual LVI to create mainframe volumes. You can also use the Create LDEV function to create a volume to be used as a system disk on either a mainframe or an open system. A system disk is not available to hosts, command devices, pool volumes, journal volumes, and so on. For more information, see “Using a system disk” (page 52). The following depicts an example of creating customized volumes.
1. 2. 3. 4. From the Drive Type/RPM list in Parity Group Selection, select the drive type and RPM. From the RAID level list in Parity Group Selection, select the RAID level. Click Select Free Spaces. In the Select Free Spaces window, in the Available Free Spaces table, select the free spaces to be assigned to the volumes. Do the following, if necessary: - To specify the conditions and show the free space, click Filter, specify the conditions, and then click Apply.
12. In Initial LDEV ID, make sure that an LDEV ID is set. To confirm the used number and unavailable number, click View LDEV IDs to open the View LDEV IDs window. 1. In Initial LDEV ID in the Create LDEVs window, click View LDEV IDs. In the View LDEV IDs window, the matrix vertical scale represents the second-to-last digit of the LDEV number, and the horizontal scale represents the last digit of the LDEV number. The LDEV IDs table shows the available, used, and disabled LDEV IDs.
Finding an LDEV ID When creating volumes, the LDEV ID (LDKC: CU: LDEV) must be specified. Use this procedure to determine the LDEV IDs in use in the storage system so you can specify the correct LDEV. 1. In Initial LDEV ID in the Create LDEVs window, click View LDEV IDs. 2. In the View LDEV IDs window, review the list to confirm the LDEV IDs. The LDEV IDs table shows the available, used, and disabled LDEV IDs.
2. 3. 4. 5. In the Change LDEV Settings window, you can change the setting of LDEV Name, Initial LDEV ID, or Processor Blade. • If you change LDEV Name, specify the prefix characters and the initial number for this LDEV. • If you change Initial LDEV ID, specify the number of LDKC, CU, DEV, and Interval. To confirm used LDEV IDs, click View LDEV IDs to confirm the used LDEV IDs in the View LDEV IDs window. • If you change Processor Blade, click the list and specify the processor blade ID.
Restoring a blocked LDEV You can restore a blocked LDEV using 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.
• An LDEV that has the Read/Write access attribute. • An LDEV with the Volume Security for Mainframe setting. When you delete an LDEV, the alias information contained in the LDEV is also deleted. Therefore, if you delete an LDEV related to an alias device, you should do one of the following: • Allocate another LDEV to the alias device, and then delete the LDEV. • Delete the LDEV first, and then allocate another LDEV to the alias device.
Storage system operation when LDEVs are formatted The storage system acts in one of two ways immediately after an LDEV is added, depending on the default settings in the storage system. • The storage system automatically formats the added LDEV. This is the default action. • The storage system blocks the LDEV instead of automatically formatting it. To confirm or change the default formatting settings on the storage system, contact the administrator.
Item Description Storage system is powered off The Quick Format operation resumes when power is turned back on. and back on Restrictions • Quick Format cannot be executed on external volumes, virtual volumes, system disks, the journal volumes of Continuous Access Journal Z and quorum disks. • The volume migration feature or the QuickRestore feature cannot be applied to volumes undergoing Quick Format.
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 45) for blocking an internal volume. See the HP XP P9000 External Storage for Open and Mainframe Systems User Guide for blocking an external volume. 1. Select the parity group containing the LDEV to be formatted. 2. Click Format LDEVs. 3.
For information about default settings of the storage system, see “Overwriting control blocks in specific external volumes” (page 51). • Deleting LDEVs (converting LDEVs to the free space). • Creating LDEVs. Overwriting control blocks in specific external volumes 1. 2. Perform zero-formatting on the mainframe system volumes to register them (see steps 1 and 2 in “Registering external volumes” (page 50)). In the Storage Systems tree, select External Storages. The External Storage Systems tab appears.
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. Changing the processor blade assigned to an LDEV 1. In the Remote Web Console main window, in the Storage Systems tree, select Logical Devices. LDEVs are shown in the LDEVs tab. 2. 3. 4. 5. 6. Select the LDEV for which you want to change the processor blade.
You can create a system disk on either a mainframe or an open system. To create a system disk, you create an LDEV and then designate it as a system disk in the Create LDEVs wizard (see “Creating an LDEV” (page 41)). The system disk designation prevents other storage system structures from accessing it. It is not available to hosts, or a command device, pool volume, journal, and so on. The system disk is part of one parity group.
4 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 Z by creating one or more Thin Provisioning Z pools (THP pools) of physical storage space.
suspending copy operations or deleting pairs. For more information about temporary license capacity, see the HP XP P9000 Remote Web Console User Guide. Pool requirements A pool is a set of volumes reserved for storing Thin Provisioning Z write data. Items Requirements Pool capacity Calculate pool capacity using the following formula: The capacity of the pool (MB) = Total number of pages × 38 - 3800. 3800 in the formula is the management area size of the pool-VOL with System Area.
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.
Requirements for increasing THP V-VOL capacity You can increase THP V-VOL capacity up to 262,668 cylinders. The following requirements are important when increasing the THP V-VOL capacity: • The emulation type is 3390-A. • The THP V-VOL to be increased is not shared with a P9500 product that does not allow increasing the THP V-VOL (See “Increasing THP V-VOL capacity” (page 129)). • The THP V-VOL is not undergoing LDEV formatting.
Using Thin Provisioning Z or Smart Tiers Z 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 Not permitted Cache Residency (HP XP P9000 Not applicable Performance for Open and Mainframe Systems User Guide) Performing operations on THP pool-VOLs, TSE-VOLs, or THP V-VOLs.
Product name (Guide name) Permitted Not permitted Volume Shredder (HP XP P9000 Volume Shredder for Open and Mainframe Systems User Guide) Use on THP V-VOLs. • Using on pool-VOLs. • Using on TSE-VOLs. • Increasing the capacity of THP V-VOL used by Volume Shredder. • Reclaiming zero pages of V-VOL used by Volume Shredder.
You cannot specify a Thin Provisioning Z or Smart Tiers Z pool-VOL as a Continuous Access Synchronous Z P-VOL and S-VOL. Continuous Access Journal Z You can use Thin Provisioning Z or Smart Tiers Z in combination with Continuous Access Journal Z to replicate THP V-VOLs. Figure 2 Using Thin Provisioning Z or Smart Tiers Z and Continuous Access Journal Z The following table lists the supported Continuous Access Journal Z and Thin Provisioning Z or Smart Tiers Z volume combinations.
Business Copy Z P-VOL Business Copy Z 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.
CAUTION: If you delete a pool, its pool-VOLs (LDEVs) will be blocked. Blocked volumes should be formatted before use. CAUTION: When data migration is done on a file-by-file basis, perform the operation to reclaim zero pages if necessary. In the case of a volume copy or the physical copy, the operation to reclaim zero pages is unnecessary. To restore the backup data: 1. Restore the V-VOL data. 2. Perform the operation to reclaim zero pages. Perform the above procedure for each V-VOL.
Tier monitoring and data relocation Smart Tiers uses tiers to manage data storage. It classifies the specified drives in the pool into tiers (storage hierarchy). Up to three tiers can be defined in a pool depending on the processing capacity of the data drives. Tiering allocates more frequently accessed data to the upper tier and less frequently accessed data, stored for a long period of time, to the lower tier. Smart Pool With Smart Tiers, you can enable the Smart Pool option for an existing pool.
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 next 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 Z or Continuous Access Journal Z 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 83). • Pool Management Task (Status/Progress) on “View Pool Management Status window” (page 293). 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.
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.
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 Z 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.

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 85). 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 86)). 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 86)).
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 86). 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 90). 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 95).
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.
see the rebalancing progress of the usage level among pool-VOLs in the View Pool Management Status window (see “View Pool Management Status window” (page 293)). Thin Provisioning Z automatically stops balancing the usage levels among pool-VOLs if the cache memory is not redundant or the pool usage rate reaches up to the threshold.

5 Configuring access attributes Volume Retention is required to assign access attributes to volumes. Access attributes strategies By default, all the volumes are subject to read and write operations by hosts. With Volume Retention, you can assign access attributes to volumes that restrict read and/or write operations as needed. By properly setting these attributes, you can prevent unauthorized access to data and avoid the possibility of data being damaged, lost, or leaked.
• If a remote copy pair is suspended during a Continuous Access Synchronous Z or Continuous Access Journal Z copy operation and you want to enable the S-VOL read option on the RCU (mode 20), you must ensure that the access attribute of the S-VOL is Read/Write before you enable the S-VOL read option. If the access attribute of the S-VOL is Read-Only, mode 20 will be disabled. Also, operations such as REFORMAT and REFVTOC cannot be performed for overwriting volume serial numbers.
Supported volume emulation types Volume Retention supports the following volume emulation types: Table 1 Supported volume emulation types Supported volume emulation types Description 3380-3, 3390-1, 3390-2, 3390-3, 3390-3R, These volumes can be used only by mainframe hosts. 3390-9, 3390-A, 3390-L, 3390-M 3380-3A, 3380-3B, 3380-3C 3390-3A, 3390-3B, 3390-3C These volumes can be used by mainframe hosts and open-systems hosts.
Specifying the VTOC size When a host accesses a volume, the volume table of contents (VTOC) in the volume changes to include updated access logs. Prerequisites • Volume has Read Only attribute. • Volume is not for a VM minidisk. Procedure 12 To specify the VTOC size: 1. 2. Click Action > Mainframe Connection > Volume Retention to open the Volume Retention window. Select an LDKC number from the LDKC list and a group that a CU belongs to from the CU Group list.
6 Protecting volumes from I/O operations This chapter provides information on Volume Security for Mainframe. Overview of Volume Security for Mainframe Hitachi Volume Security for Mainframe protects data on your P9500 (P9500) from I/O operations performed at mainframe hosts. Security can be applied to logical volumes to prohibit read/write operations from specified mainframe hosts to specified logical volumes.
Protecting Volumes from I/O Operations at Mainframe Hosts Volume Security for Mainframe enables you to protect volumes from unauthorized access by mainframe hosts. To protect volumes from unauthorized access, you must create security groups and register mainframe hosts and volumes in security groups. Security groups are classified in access groups or pool groups. If you want to allow some but not all mainframe hosts to access volumes, you must classify the security group as an access group.
Port-Level Security Usually, hosts are connected to two or more ports with cables and have access to volumes through these ports. In the security example shown in the previous figure, hosts can access volumes in their access group through any port connected to the hosts. With the Volume Security Port Security Option for Mainframe you can permit or prohibit hosts from accessing volumes through specified ports.
If no ports are registered in a host group, hosts in the host group can access volumes through ports connected to the hosts. Port-level security is a security policy used to permit access by hosts to volumes through ports registered in host groups and to prohibit access through unregistered ports. CAUTION: Before applying security, you must confirm which hosts are performing I/O operations on which volumes in the access groups.
volumes (vol_A and vol_B) in a pool group, all the mainframe hosts connected to your storage system will be unable to access vol_A and vol_B. To register volumes in a pool group, you must create an LDEV group, register the volumes in the LDEV group, and then register the LDEV group in the desired pool group. A pool group may contain only one LDEV group.
Warnings Regarding Volume Security for Mainframe This section provides specific warnings and advice related to security settings. WARNING! 1. Do not apply security to volumes on which any job is running. If you apply security to such a volume, the job may end abnormally. 2. When applying security, make sure that your security settings are correct. If incorrect security settings are made, the system will be difficult or impossible to control. 3.
• If you are using Parallel Access Volumes: If you apply security to a Parallel Access Volumes base volume, the security settings will also apply to the corresponding alias volume. • To ensure normal system operation, take care in making security settings on the base-volume with alias volume access. For the Linux host: If a Linux host is registered to a host group, connect a storage system to a Linux host. Then register the Linux host to the host group.
Procedure 13 To start Volume Security for Mainframe 1. 2. Open the Remote Web Console main window. For details, refer to HP P9000 Remote Web Console User Guide.

For the problems and solutions regarding the Remote Web Console, see the HP XP P9000 Remote Web Console User Guide Troubleshooting Thin Provisioning Z The following table provides troubleshooting instructions for using Thin Provisioning Z.
Problems Causes and Solutions Solutions: • Add some pool-VOLs to the pool. See “Increasing pool capacity” (page 123). • Perform the operation to reclaim zero pages in order to release pages in which zero data are stored. See “About releasing pages in a THP V-VOL” (page 130). • Increase the value of Subscription Limit for the pool. See “Changing the pool subscription limit” (page 119). • Ask HP Technical Support to solve the problem. Cannot add a pool-VOL.
Problems Causes and Solutions A pool cannot be deleted. Causes: • The pool usage is not 0. • External volumes are removed from the pool before you delete the pool. • THP V-VOLs have not been deleted. Solutions: • Confirm that the pool usage is 0 after the THP V-VOLs are deleted, and then you can delete the pool. • Ask HP Technical Support to solve the problem. A failure occurs to the application for monitoring the volumes installed in a host. Causes: • Free space of the pool is insufficient.
Problems Causes and Solutions Cannot reclaim zero pages in a THP V-VOL. Causes: • Zero pages in the THP V-VOL cannot be reclaimed from Remote Web Console because the THP V-VOL does not meet conditions for releasing pages in a THP V-VOL. Solutions: • Make sure that the THP V-VOL meets the conditions described in “Releasing pages in a THP V-VOL” (page 131). The THP V-VOL cannot be released if the process to reclaim zero pages in the THP V-VOL is interrupted.
If an error occurs during the operations, the error code and error message appear in the error message dialog box. For more information about error messages, see the HP XP P9000 Remote Web Console Messages. Troubleshooting provisioning while using RAID Manager If an error occurs while operating Data Retention or Thin Provisioning Z while using RAID Manager, you might identify the cause of the error by referring to the log appearing on the RAID Manager window or the RAID Manager operation log file.
Error Code (SSB2) Error Contents Solutions 0xaf2b Because the specified volume operation was not Re-execute the operation after a brief interval. finished, the operation was rejected. 0xaf2c Because the shared memory capacity is not enough to increase the specified capacity, the operation was rejected. Confirm the value immediately below LDEV Capacity in the Expand Virtual Volumes window.
1. 2. 3. 4. In the Error Detail dialog box, click the arrow button at the right end of the Host list • If the list shows only one entry, only one host is causing the error. • If the list shows two or more entries, two or more hosts are causing the error. Select a host from the Host list. Right-click the arrow button at the right end of the CU list, and then check how many CU images are displayed in the list.
