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. 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: • In mainframe systems, and on open systems in some scenarios. 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 on a server. It requires fewer logical devices, but larger ones.
Thin provisioning Thin provisioning is an approach to managing storage that maximizes physical storage capacity. Instead of reserving a fixed amount of storage, it simply removes capacity from the available pool when data is actually written to disk.
For detailed information, see (page 46). When to use Thin Provisioning Z Thin Provisioning Z is a best fit in a mainframe environment in the following scenarios: • Where the aggregation of storage pool capacity usage across many volumes demonstrates largest performance optimization. • For stable environments and large consistently growing files or volumes. • If the application or Data Facility Storage Management Subsystem (DFSMS) does not write over areas that are not immediately needed.
The example on the left (Today), before installing Thin Provisioning Z software, shows higher starting cost because a larger amount of physical disk capacity is purchased to configure the entire volume capacity. Much of this hardware-centric capacity is unused at the start. Over time, you will have to reconfigure the storage based on the volume capacity to be consumed, for example, if the volume capacity exceeds 80% after one year.
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, much like sharing a port in two organizations but not in a parity group. Resource groups should be planned and created before creating volumes. For more information, see (page 15).
System requirements • The P9500 hardware, microcode, and Remote Web Console essential for operating the storage system be installed and configured for use. • A P9500 storage system. • The storage system must have parity groups installed. • A Remote Web Console client computer. Shared memory requirements If configuring thin provisioning, Thin Provisioning Z requires dedicated shared memory for the V-VOL management area.
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.
User groups User groups and associated built-in roles are defined in the SVP. A user belongs to one or more user groups. Privileges allowed to a particular user are determined by the user group or groups to which the user belongs. The Security Administrator assigns resource groups to user groups. A user group may already be configured, or a new user group may be required for certain resources. See HP P9000 Remote Web Console User Guide for more information about how to set up user groups.
Guidelines • If you are providing a virtual private storage system to different companies, you should not share parity groups, external volumes, or pools if you want to limit the capacity that can be used by each user. When parity groups, external volumes, or pools are shared between multiple users, and if one user uses too much capacity of the shared resource, the other users might not be able to create an LDEV.
7. 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. Removing resources from a resource group Before removing remove resources from a resource group, consider the following: • The resources removed from a resource group are returned to the meta_resource. • Resources cannot be deleted from the meta_resource.
Deleting a resource group You cannot delete the following: • The meta_resource. • A resource group that is assigned to a user group. • A resource group that has resources assigned to it. Procedure 5 To delete a resource group 1. 2. 3. 4. In the Remote Web Console main window, in the Storage Systems tree, click Administration, and then Resource Groups. Click one or more resource groups to delete in the Resource Groups tab. Click Delete Resource Groups.

3 Configuring custom-sized provisioning Configuring custom-sized provisioning involves creating and configuring a customized volume (CV). A CV is a fixed-sized volume that is divided into arbitrary sizes. This provisioning strategy is suitable for use on both open and mainframe systems. Virtual LVI or Virtual LUN software is required to configure variable-sized provisioning.
Parameter Mainframe system 1,024 for other RAID levels Maximum number of volumes (normal and 65,280 Virtual LVI per storage system Minimum size for one Virtual LVIvolume 1 user cylinder (+ control cylinders) Maximum size for one Virtual LVI volume See “CV capacity by emulation type for mainframe systems” (page 27) Size increment 1 user cylinder Disk location for Virtual LVI volumes Anywhere CV capacity by emulation type for mainframe systems Emulation type Minimum CV capacity (cyl) Maximum CV ca
Emulation type Minimum CV capacity (cyl) Maximum CV capacity (cyl) Number of control cylinders (cyl) 1. For 3390-A, the incremental unit of the CV capacity is the capacity from 0 to 65,520 cylinders is defined as the 1 user-cylinder, and the capacity from 65,521 to 262,668 cylinders is defined as the 1,113 user-cylinder. Therefore, if you specify a value in Remote Web Console in the Create LDEVs window that exceeds 65,520 cylinders, the value is corrected to multiples of 1,113 cylinders.
ceil((user-specified-CV-capacity + management-area-capacity) * 15 * capacity-of-a-slot / boundary-value) * boundary-value * 1024 or ceil((user-specified-CV-capacity + management-area-capacity) * 15 * capacity-of-a-slot / boundary-value) * boundary-value / capacity-of-a-slot / 15 where • the value enclosed in ceil( ) must be rounded up to the nearest whole number. • user-specified-CV-capacity is the capacity of the user area in a CV expressed in cylinders. • boundary-value is expressed in kilobytes.
drive, the boundary value depends on volume emulation types and RAID levels (see “Capacity of a slot” (page 32)) • The resulting entire capacity is expressed in blocks. To convert the resulting entire capacity into megabytes, divide this capacity by 2,048.
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 32)). • 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. • The resulting entire capacity is expressed in slots.
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.
A SATA drive requires 3390-xx for mainframe systems. Emulation type 3390-xx SATA-E (slots) RAID 1 (2D+2D) RAID 5 (3D+1P) RAID 5 (7D+1P) RAID 6 (6D+2P) 445,440 2,004,480 10,913,280 8,017,920 *xx is a variable indicating one or more numbers or letters. Create LDEV function Use the Create LDEV function to create a customized variable-sized volume. You need Virtual LVI to create a mainframe volume.

In the Create LDEVs window, from the Provisioning Type list, select a provisioning type for the LDEV to be created. • If creating internal volumes, select Basic. • If creating external volumes, select External. In System Type, select Mainframe to create mainframe volumes. From the Emulation Type list, select an emulation type for the selected system type. If creating an internal volume, select the parity group, and then do the following: 1.
11. Click Options to show more options. 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.
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. 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. In the table, used LDEV numbers appear in blue, unavailable LDEV numbers appear in gray, and unused LDEV IDs appear in white.
5. In the Confirm window, verify the settings, and then click Apply. The settings are changed. If Go to tasks window for status is checked, the Tasks window opens. Removing an LDEV to be registered If you do not want to register an LDEV that is scheduled to be registered, you can remove it from the registering task. 1. In the Selected LDEVs table in the Create LDEVs window, select an LDEV, and then click Remove. 2. Click Finish. 3. In the Confirm window, click Apply.
3. Select the blocked LDEV, and then click Restore. Select multiple LDEVs using the Shift key (if the LDEVs are adjacent), or using the Ctrl key (if the LDEVs are not adjacent). 4. 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. Editing an LDEV name You can edit the name of a registered internal volume.
Formatting LDEVs If you initialize LDEVs that are being used, you will need to format the LDEVs.
Quick Format cannot be performed on the following volumes: • Any volumes other than internal volumes • Pool volumes • Journal volumes Quick Format specifications Item Description Preparation for executing Quick Format The internal volume must be in blocked status. However, you do not need to create the system disk. The number of parity groups that can undergo Quick Format Up to 36 parity groups can concurrently undergo Quick Format.
information about how to perform zero-formatting, see the documentation for your external storage system. Formatting a specific LDEV This procedure performs Normal formatting on the volume. 1. Select and block the LDEV to be formatted. See “Blocking an LDEV” (page 37) for blocking an internal volume. See the HP P9000 External Storage for Open and Mainframe Systems User Guide for blocking an external volume. 2. 3. 4. Click Format LDEVs.
1. Perform zero-formatting on the external mainframe volumes. Zero-formatting writes 0’s in the entire disk area, formatting the entire disk area. For information about how to perform zero-formatting, see the documentation for your mainframe or external storage system. 2. Map the zero-formatted external volumes using External Storage to register the volume in the external volume group. For more information, see the HP P9000 External Storage for Open and Mainframe Systems User Guide.
Assigning a processor blade Assigning a processor blade to a resource You can assign a processor blade to resources (logical devices, external volumes, and journal volumes). 1. In the Remote Web Console main window, in the Storage Systems tree, select Components. 2. In Components, select the name of the DKC for which you want to assign a processor blade. Processor blades can be viewed in the Processor Blades tab. 3. 4. 5. 6.
For example, when the system disk is used as an audit log buffer, you set parameters to enable the audit log buffer. The Audit Log feature recognizes the LDEV number of the system disk and then accesses it as a buffer. The system disk must have sufficient capacity to accommodate the audit log buffer. See Hitachi Audit Log User Guide for more information about how to enable the audit log buffer.
Guidelines • Although the system disk can be created in an external volume, it is best to make it in an internal volume. • Although there can be up to 16 volumes of the system disk made throughout the entire storage system, best practice is to have only one system disk per storage system. • If you have more than one system disk on your storage system, and one of them is blocked, the unblocked system disks may not be usable.
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 using multiple LDEVs.
Items Requirements Reducing capacity You can reduce pool capacity by removing pool-VOLs. Deleting You can delete pools that are not associated with any THP V-VOLs. Subscription limit You can set the subscription limit on a THP V-VOL. This limits the percentage of THP V-VOL capacity that can be created for the pool capacity and avoids THP V-VOL blocking caused by a full pool.
Items Requirements For pool-VOLs in a pool: • RAID 6 is the recommended RAID level for pool-VOLs, especially for a pool where the recovery time of a pool failure due to a drive failure is not acceptable. • For pool-VOLs where the same drive type is defined, pool-VOLs of different RAID levels cannot coexist in a pool. Drive type for a Thin SAS 15K, SAS 10K, SAS 7.2K, SATA-W/V, SATA-E, and SSD can be used as drive types.
• The capacity to be added to the THP V-VOL must be specified within the range indicated below LDEV Capacity in the Expand V-VOLs window. • You cannot add capacity to the THP V-VOL unless the pool related to the target THP V-VOL is in any one of the following statuses: ◦ Normal ◦ Exceeding subscription limit threshold ◦ In progress of pool capacity shrinking CAUTION: When increasing THP V-VOL capacity, do not perform the following operations.
Using Thin Provisioning 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 P9000 Not applicable Performance for Open and Mainframe Systems User Guide) Performing operations on THP pool-VOLs or THP V-VOLs.
Product name (Guide name) Permitted Not permitted Compatible XRC (HP P9000 for Compatible XRC User Guide) Using a THP V-VOL as a Compatible XRC P-VOL or S-VOL. • Using a THP pool-VOL as a Compatible XRC P-VOL or S-VOL. • Increasing the capacity of THP V-VOL used by Compatible XRC. Compatible FlashCopy (HP P9000 for Using a THP V-VOL as a Compatible Compatible FlashCopy Mirroring User FlashCopy P-VOL or S-VOL. Guide) • Using a THP pool-VOL as a Compatible FlashCopy P-VOL or S-VOL.
The following table lists the interaction when the Business Copy Z S-VOL and T-VOL are also THP V-VOLs. Business Copy Z S-VOL Business Copy Z T-VOL Explanation THP V-VOLs THP V-VOLs Supported. THP V-VOLs Normal (ordinary) volumes Supported. The Quick Restore function is unavailable. Normal volumes (all volumes THP V-VOLs that are not THP V-VOLs) Supported. Note, however, that this combination consumes the same amount of pool capacity as the normal volume (P-VOL).
Working with pools About pools Thin Provisioning Z 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 65,232 THP V-VOLs per pool. A pool number must be assigned to a pool. Multiple THP V-VOLs can be related to one pool.
Status Explanation SIM code* Blocked The pool is full or an error occured in the pool, therefore the pool is blocked. 622XXX or 623XXX *XXX in the SIM code indicates the pool number. Creating a pool The following procedure tells how to create a pool using Remote Web Console. This procedure is for setting up Thin Provisioning Z. Before creating a pool, you must install the proper amount of shared memory, and you must have a V-VOL management area in shared memory.
- To change a pool-VOL to the top pool-VOL in the Selected Pool Volumes table, select the pool-VOL and then click Change Top Pool Vol. 6. Click OK. The information in the Selected Pool Volumes table is applied to Total Selected Pool Volumes and Total Selected Capacity. 8. In Pool Name, specify a name for this pool: 1. In Prefix, type the characters that will become the fixed characters for the beginning of the pool name. The characters are case-sensitive. 2.
Procedure 8 To create a THP V-VOL 1. 2. 3. 4. 5. Click Create LDEVs. In the Create LDEVs window, in Provisioning Type, confirm Thin Provisioning is selected. In System Type select Mainframe. In Emulation Type, confirm 3390-A is selected. Select the pool. 1. From the Drive Type/RPM list in Pool Selection, select the drive type and RPM. 2. From the RAID level list, select the RAID level. 3. Click Select Pool. The Select Pool window opens. 4. In the Available Pools table, select a pool.
14. If necessary, change the settings of the THP V-VOLs. • To edit the SSID, click Edit SSIDs to open the SSID’s window (see “Editing a THP V-VOL's SSID” (page 57)). • To change LDEV settings, click Change LDEV Settings to open the Change LDEV Settings window (see “Changing THP V-VOL settings” (page 57)). 15. If necessary, delete a THP V-VOL from the Selected LDEVs table. Select a THP V-VOL to be deleted, and then click Remove (see “Removing the THP V-VOL to be registered” (page 58)). 16. Click Add.
5. In the Confirm window, click Apply. The setting is changed. If Go to tasks window for status is checked, the Tasks window opens. Removing the THP V-VOL to be registered If you do not want to register the THP V-VOL, you can remove it from the registering task. 1. In the Selected LDEVs table in the Create LDEVs window, select the LDEV, and then click Remove. 2. Click Finish. 3. In the Confirm window, click Apply. The LDEV is removed. If Go to tasks window for status is checked, the Tasks window opens.
The subscription limit is the ratio (%) of the total THP V-VOL capacity that has been configured to the total capacity of the pool. When the subscription limit is set, you cannot configure another THP V-VOL if the new THP V-VOL capacity would cause the subscription limit to be be exceeded. For example, if the pool capacity is 100 GB and the subscription limit is 150%, you can configure up to a total of 150 GB of capacity to the THP V-VOLs related to the pool.
3. 4. Click More Actions, and then select Edit Pools. In the Edit Pools window, check Subscription Limit, and then type the subscription limit percentage. If the subscription limit is blank, then it is disabled, and any amount of THP V-VOLs can be created regardless of the pool free capacity. 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.
Codes (XXX = hexidecimal pool number) Event 627XXX Pool-VOL is blocked 640XXX Thresholds or Values Types of reports Report to the Completion host report to Remote Web Console Information to the operator Not applicable Yes No Yes V-VOL management Not applicable area cannot be saved to a pool No No Yes Automatic completion of a SIM Some SIMs are completed automatically when you resolve the problem that caused the SIM.SOM 734 must be enabled for automatic completion of a SIM.
4. 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. It takes time if many SIMs need to be completed. If Go to tasks window for status is checked, the Tasks window opens. You can check whether a SIM completes successfully in the Remote Web Console main window. For details, see the HP P9000 Remote Web Console User Guide. Managing pools and THP V-VOLs Viewing pool information 1. 2.
If Mixable is set to Disable, note the following when adding the pool-VOL to the pool: • Pool-VOLs of different RAID levels cannot coexist. • Internal and external volumes cannot coexist. Procedure 9 To increase pool capacity 1. 2. 3. 4. In the Remote Web Console main window, in the Storage Systems tree, select Pool. From the Pools table, select the pool for which you want to increase the capacity. You cannot increase pool capacity for multiple pools. Click Expand Pool.
1. In the Remote Web Console main window, in the Storage Systems tree, select Pool. The pool name appears below Pool. 2. From the Pool table, select the pool to be recovered. Select multiple pools using the Shift key (if the pools are adjacent), or using the Ctrl key (if the pools are not adjacent). 3. 4. 5. Click More Actions, and then select Restore Pools. The Restore Pools window opens with a list of the pool or pools selected in the previous step. To restore those pools, click Apply.
If pool capacity is decreased soon after creating a pool or adding a pool-VOL, processing may take a while to complete. • You cannot delete the top pool-VOL in the pool. For Thin Provisioning, this means that the RAID level for the drive type/RPM of the top pool-VOL is fixed. • When deleting the pool-VOL causes the used capacity to exceed the pool threshold, you cannot delete the pool-VOL.
2. From the Pool table, select the pool to be deleted. Select multiple pools using the Shift key (if the pools are adjacent), or using the Ctrl key (if the pools are not adjacent). 3. Click More Actions, and then select Delete Pools. The Delete Pools window opens. You cannot delete a pool whose usage is not 0%, or a pool for which THP V-VOLs are assigned. 4. Click Finish. The Confirm window opens. To continue with the shredding operation and delete volume data, click Next.
2. From the table, select the THP V-VOL for which you want to change the name. Select multiple THP V-VOLs using the Shift key (if the THP V-VOLs are adjacent), or using the Ctrl key (if the THP V-VOLs are not adjacent). 3. Click Edit LDEVs. When you selected THP V-VOLs from the Virtual Volumes table, click More Actions, and then Edit LDEVs. The Edit LDEVs window opens. 4. Check LDEV Name and change the LDEV name, if necessary. 1.
