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. Provisioning a storage system requires balancing the costs of the solution with the benefits that the solution provides.
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.
y Disadvantages Some disadvantages to using fixed-sized provisioning are: • If you use only part of the entire capacity specified by an emulation type, the rest of the capacity is wasted. • You cannot use the capacity efficiently. The size of the drive is fixed. When you create a fixed-sized volume, a small amount of capacity remains permanently inaccessible.
To change the size of a volume already in use, you first create a new volume larger (if possible) than the old one, and then move the contents of the old volume to the new one. The new volume would be remapped on the server to take the mount point of the old one, which is retired. A disadvantage is that this manual intervention can become costly and tedious and this provisioning strategy is appropriate only in certain scenarios.
When to use expanded-LU provisioning Expanded-LU provisioning is a best fit in the following scenarios: • In an open systems environment. • When you want to manually control and monitor your storage resources and usage scenarios. • To combine open-systems volumes to create an open-systems volume (LU) larger than 2.8 TB. • When thin provisioning is not an option.
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.
Thin Provisioning concepts Thin Provisioning is a volume management feature that allows storage managers and System Administrators to efficiently plan and allocate storage to users or applications. It provides a platform for the array to dynamically manage data without host involvement. Thin Provisioning provides two important capabilities: thin provisioning of storage and enhanced volume performance. Thin Provisioning is more efficient than traditional provisioning strategies.
Advantages Without Thin Provisioning With Thin Provisioning Some file systems take up little pool space. For more details, see “Operating system and file system capacity” (page 67). Reduces management costs You must stop the disk array to reconfigure it. When physical capacity becomes insufficient, you can add pool capacity without service interruption.
The example on the left (Today), before installing Thin Provisioning 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.
Smart Tiers 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). Using , you can configure a storage system with multiple storage tiers using different kinds of data drives, including SSD, SAS, SATA, and external volumes. This helps improve the speed and cost of performance.
Smart Tiers simplifies storage administration by automating and eliminating the complexities of efficiently using tiered storage. It automatically moves data on pages in Thin Provisioning virtual volumes to the most appropriate storage media, according to workload, to maximize service levels and minimize total cost of storage.
Data retention strategies After provisioning your system, you can assign access attributes to open-system volumes to protect the volume against read, write, and copy operations and to prevent users from configuring LU paths and command devices. Use the Data Retention to assign access attributes. Resource groups strategies A storage system can connect to multiple hosts and be shared by multiple divisions in a company or by multiple companies.
Term Description subscription threshold In a thin provisioned storage system, the proportion (%) of total V-VOL capacity associated with the pool/pool capacity to the total capacity. You can set the percentage of V-VOL capacity that can be created to the total capacity of the pool. This will prevent V-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.
7. The Security Administrator assigns resources to the resource groups. See “Adding resources to a resource group” (page 32) for more information. 8. The Security Administrator assigns each Storage Administrator to each user group. See HP P9000 Remote Web Console User Guide for more information. After the above procedures, the Storage Administrators in A and B divisions can manage the resource groups assigned to their own division.
3. The Security Administrator assigns the resource groups tocreates user groups. See HP P9000 Remote Web Console User Guide for more information. 4. 5. The Storage Administrator in the system division sets ports. The Security Administrator createsassigns the resource groups to user groups. See HP P9000 Remote Web Console User Guide for more information. 6. 7. The Storage Administrator in the system division sets ports. The Security Administrator assigns resources to the resource groups.
Storage Administrator (with View and Modify privileges) and All Resource Groups Assigned is Yes on that user account, the user can edit the storage for all the resources. If allowing this access becomes a problem with security on the storage system, then register the following two user accounts in Remote Web Console and use these different accounts for different purposes. • A user account for a Security Administrator where All Resource Groups Assigned is set to Yes.
Procedure 1 To create 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 Create Resource Groups in the Resource Groups tab. 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.
3. 4. Select one or more resources to remove from the resource group, and then click Remove Resources. 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. Managing Resource Groups Changing the name of a resource group When changing the name of a resource group, observe the following: • The name meta_resource cannot be changed.

3 Configuring custom-sized provisioning Configuring custom-sized provisioning involves creating and configuring a customized volume (CV). A CV is a fixed-sized volume that is divided into arbitrary sizes. This provisioning strategy is suitable for use on both open and mainframe systems. Virtual LVI or Virtual LUN software is required to configure variable-sized provisioning.
Parameter Open system Maximum number of volumes (normal and 65,280 Virtual LUN) per storage system Maximum size for one Virtual LUN volume See “CV capacity by emulation type for open systems” (page 45) Size increment 1 MB Disk location for Virtual LUN volumes Anywhere CV capacity by emulation type for open systems Emulation type* Minimum CV capacity (CYL) Maximum CV capacity Number of control cylinders (cyl) OPEN-V 48,000 KB 3,221,159,680 KB (2.

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, from the Processor Blade list, select a processor blade to be used by the LDEVs. • If you assign a specific processor blade, select the ID of the processor blade. • If you can assign any processor blade, click Auto. 14. If you are creating one more system disks, select Create LDEVs as System Disk. 15. Click Add. The created LDEVs are added to the Selected LDEVs table.
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.
• A journal volume. • A remote command device. • A volume security volume. • A quorum disk. 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 where: • X indicates the number of parity groups on which Quick Format is being performed. • Y indicates the number of parity groups where all volumes are blocked during the Quick Format. Storage system is powered off Quick Format resumes if you turn the power back on. and on Restrictions • Quick Format cannot be executed on external volumes, virtual volumes, system disks, the journal volumes of Continuous Access Journal and quorum disks.
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.
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. To designate the system disk as the buffer area for audit logs, do one of the following: • In the Audit Log Setting window, set Audit Log Buffer to Enable. • Set system option mode (SOM) 676 to ON. You can create a system disk on either a mainframe or an open system.
• In a mixed configuration of open and mainframe volumes in a storage system, it is best to select open volumes for the system disk. • 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. In this case, delete the blocked system disk, and then use the other normal system disks.
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 by creating one or more Thin Provisioning pools (THP pools) of physical storage space using multiple LDEVs.
Smart Tiers License requirements Using of Smart Tiers on the P9500 storage system requires the following: • Both the Thin Provisioning and the Smart Tiers software have been installed and the license key enabled on the Remote Web Console computer. • You will need the Smart Tiers license for the total capacity of the pool for which the tier function is enabled.
Items Requirements This setting can restore the ability to shrink the pool, create the THP V-VOL, and expand the THP V-VOL. Utilization thresholds • Warning Threshold: You can set the value between 1% and 100%, in 1% increments. The default is 70% (recommended). • Depletion Threshold: You can set the value between 1% and 100%, in 1% increments. The default is 80%.
Items Requirements • For internal and external pool-VOLs to coexist, the cache mode of the external volume must be set to enable. • Mixable on the Remote Web Console window must be enabled for the internal volume and external volume to coexist. • The pool-VOL of RAID 1 cannot coexist with pool-VOLs of RAID 5, RAID 6, or an external volume. RAID level for a Smart Tiers pool Pool-VOLs of RAID 5, RAID 6, or an external volume can coexist in a pool. Pool-VOLs of RAID 1 cannot be registered.
Items Requirements Volume capacity Volume capacity from 46.87 MB to 59.9 TB per volume. • TB: 0.01 to 59.99 • GB: 0.04 to 61,439.99 • MB: 46.87 to 62,914,556.25 • Blocks: 96,000 to 128,849,011,200 However, if you use the volume as a P-VOL or S-VOL of Business Copy, Continuous Access Synchronous, Continuous Access Journal, or External Storage Access Manager, the volume capacity must be 4 TB or less. Total maximum volume capacity of 1.1 PB per storage system. Path definition Available.
• The capacity to be added to the THP V-VOL must be specified within the range indicated below LDEV Capacity in the Expand V-VOLs window. • You cannot add capacity to the THP V-VOL 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.
OS File System Metadata Writing Pool Capacity Consumed The default block size for these file systems is 4 KB. This results in 33% of the THP V-VOL acquiring THP pool pages. If the file system block size is changed to 2 KB or less then the THP V-VOL Page consumption becomes 100%. Solaris AIX HP-UX UFS Writes metadata in 52-MB increments. Size of THP V-VOL.

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).
Smart Tiers About tiered storage In a tiered storage environment, storage tiers can be configured to accommodate different categories of data. A tier is a group of storage media (pool volumes) in a THP pool. Tiers are determined by a single storage media type. A storage tier can be one type of data drive, including SSD, SAS, SATA, or external volumes. Media of high-speed response performance make up the upper tiers. Media of low-speed response or cost become the lower tiers.
Tier monitoring and relocation cycles Performance monitoring and tier relocation can be set to execute in one of two execution modes: Auto and Manual. You can set up execution modes, or switch between modes by using either the Remote Web Console RAID Manager. In Auto execution mode, monitoring and relocation are continuous and automatically scheduled. In Manual execution mode, the following operations are initiated manually.
Explanation of the relocation flow: 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. A free page is selected for allocation from an upper tier with a free page. If the capacity of all the tiers is insufficient, an error is sent to the host. 2.
Monitoring mode settings (see “Monitoring modes” (page 82)) 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 averge of I/O data that uses recent monitor cycle data, along with historical data on the performance graph. 4.
performance utilization percent shows 100%, this indicates that the target I/O load to a tier is beyond the limit performance value. CAUTION: The limit performance value is proportional to the capacity of the pool volume used in the tier. The total capacity of the parity groups 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.
When tier relocation is canceled Solution* Collected monitoring information is discarded (see “Collected Collect monitoring information again. monitoring information is discarded” (page 77). The execution mode is Auto, and the tier relocation is not completed in an execution cycle. Because the tier relocation in the next cycle is started automatically, an action for this problem is unnecessary. The execution mode is Manual and relocation is stopped.
Smart Tiers cache specifications and requirements The following cache capacity is required when the total capacity is 128 TB: • Recommended capacity of cache memory for data: 28 GB • Required capacity of cache memory for control information for using Thin Provisioning: 8 GB • Required capacity of cache memory for Smart Tiers: 4 GB • Therefore, 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.
Viewing monitor and tier relocation information Monitor and tier relocation information appears in the Remote Web Console as follows: • Monitoring Status appears in the “Pools window after selecting pool (Pools window)” (page 245) and “Top window after selecting a pool volume group under Pool” (page 249). Shows the status of pool monitoring: ◦ In Progress: Monitoring is being performed. ◦ During Computation: The calculations are being processed. Other than these cases, a hyphen appears.
Manual execution mode In Manual execution mode, you can manually collect monitoring data and relocate a tier. You can execute commands to do the following: 1. Start monitoring. 2. Stop monitoring. 3. Perform tier relocation. The following illustrates tier relocation processing when in Manual execution mode: Viewing monitor and tier relocation information If the raidcom get thp_pool command is executed by specifying the -key opt option, monitoring information and tier relocation information appear.
Monitoring modes When you create or edit a pool, you must specify the type of Smart Tiers monitoring mode to be used: Period mode or Continuous mode. If you change the monitoring mode from one to the other during monitoring, the new setting becomes effective when the next monitoring starts. Period mode Period mode is the default setting. If Period mode is enabled, tier range values and page relocations are determined based solely on the monitoring data from the last complete cycle.
average efficiency is calculated based on very different duration (short and long) periods information obtained in the past cycles. Unlike Period mode, which usually has a longer monitor cycle time, Continuous mode can effectively manage workload and tiers using a short or long duration cycle. Note that the shorter monitor cycles tend to be more responsive to relocating new workloads.
2. 3. 4. In the Pool window, click More Actions > Tier Relocation Log. In the progress dialog box, click OK. A dialog box opens allowing you to select where to download the file. Specify the folder in which to download the file, and then click Save. If you change the file name from the default, make sure the file name contains the .tsv extension before saving a renamed file.
Tiering policy examples The following figure shows an example of data allocation when the default tiering policy level All is specified. Pages in the THP V-VOL are relocated to any tier. The following figure shows an example of data allocation when setting the tiering policy to tier 1 (see Level 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.
Example of adding a tier If no tier appropriate to the added pool-VOLs is in the pool, the tier is added to the appropriate position according to its performance. The following figure illustrates adding a tier. Example of deleting a tier If a tier runs out of the 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 selected with performance graph Number of tiers in pool 1 tier Level 2 Level 3 Level 4 Level 5 2 tiers 3 tiers You cannot select these settings while displaying the performance graph. Use a setting of All instead. You cannot select these settings while displaying the performance graph. Use a setting of All instead. In the performance graph, you can display the frequency distribution of a THP V-VOL assigned to level 5.
Notes on setting tiering policy 88 • 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 89).
allocated to the tier nearest to the specified tier. When a tier is over-commited, the tier to be assigned is as follows: • ◦ When tier 1 is over-committed, the pages are allocated to tier 2. If tier 2 is over-committed, the unallocated pages are allocated to tier 3. ◦ When tier 2 is over-committed, the pages are allocated to tier 1. If tier 1 is over-committed, the unallocated pages are allocated to tier 3. ◦ When tier 3 is over-committed, the pages are allocated to tier 2.
Changing the tiering policy level of a THP V-VOL 1. In the Remote Web Console main window, in the Storage Systems tree, select Logical Devices. The 1. 2. 3. 2. following is another way to select LDEVs. In the Remote Web Console main window, in the Storage Systems tree, select Pool.

The total pool capacity combines the capacity of all the registered pool-VOLs assigned to the pool. Pool capacity is calculated using the following formulas: • 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 where • floor( ) means to truncate the part of the formula within the parentheses after the decimal point.
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. Not applicable Warning The pool-VOL in the pool is blocked or the pool is If the pool-VOL is blocked, SIM code 627XXX being shrunk. is reported. Exceeded Threshold The pool usage level may exceed the pool threshold. 620XXX, 621XXX, or 626XXX, or 626000 Blocked The pool is full or an error occurred in the pool, therefore the pool is blocked.
NOTE: The top pool-VOL cannot be deleted from the pool in the future. Take care when configuring tiers because the tier to which the top pool-VOL belongs also can never be deleted. When adding external volumes, note the following: - Cache Mode of the external volumes to be added must all be enabled, or all disabled. - An internal volume and an external volume whose Cache Mode is set to Disable cannot coexist.
performance monitoring continues until the time when you specify as the ending time on the next day. - 30 minutes, 1 Hour, 2 Hours, 4 Hours or 8 Hours: Performance monitoring is performed once every cycle you selected, starting at 00:00 hours.

The following techniques using ShadowImage or Hitachi Tiered Storage Manager will move a THP V-VOL. ◦ The THP V-VOL is copied using Business Copy from a pool with an I/O bottleneck. For more information, see HP P9000 Business Copy User Guide.
Thresholds About pool utilization thresholds Thin Provisioning monitors pool capacity using thresholds. A threshold is the proportion (%) of used capacity of the pool to the total pool capacity. Each pool has its own pool threshold values. • Warning Threshold: Set the value between 1% and 100%, in 1% increments. The default is 70%. • Depletion Threshold: Set the value between 1% and 100%, in 1% increments. The default is 80%.
Changing pool thresholds 1. In the Remote Web Console main window, in the Storage Systems tree, select Pool. The pool name appears below Pool. 2. From the Pools table, select the pool for which you want to change the threshold. 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 Edit Pools.

6. 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. Working with SIMs About SIMs Thin Provisioning and Smart Tiers provide Service Information Messages (SIMs) to report the status of the THP V-VOLs and pools. The SIM level is Moderate.
Automatically completing 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. Automatic completion of a SIM removes it from the system with no additional manual intervention. After the SIM is automatically completed, the status of the SIM changes to completed in Remote Web Console in the Confirm window. The following SIMs occur when the usage level of the pool exceeds the threshold.
Managing pools and THP V-VOLs Managing pools and THP V-VOLs includes the following tasks: • “Viewing pool information” (page 110) • “Increasing pool capacity” (page 111) • “Changing pool thresholds” (page 107) • “Changing the pool subscription limit ” (page 107) • “Changing a pool name” (page 112) • “Recovering a blocked pool” (page 112) • “Decrease pool capacity” (page 113) • “Stopping decreasing pool capacity” (page 114) • “Deleting a pool” (page 115) • “Increasing THP V-VOL capacity” (
Increasing pool capacity Adding the pool-VOL to the pool created for Thin Provisioning or Smart Tiers increases the pool capacity. The amount of pool capacity registered in the pool represents the pool capacity. You need to check the pool free capacity to increase the pool capacity, if required. However, you cannot increase the pool capacity while it is being shrunk.
- From Filter option, select ON to filter the rows. - Click Select All Pages to select all pool-VOL in the table. - Click Options to specify the unit of volumes or the number of rows to be viewed. 3. Click OK. The Select Pool Volumes window closes. The number of the selected pool volumes appears in Total Selected Pool Volumes, and the total capacity of the selected pool-VOL appears in Total Selected Capacity. 5. 6. Click Finish.
Decrease pool capacity About decreasing pool capacity You can decrease pool capacity by deleting pool-VOLs. When you delete a pool or decrease the pool capacity, the released pool-VOLs (LDEVs) will be blocked. If they are blocked, format them before using them. If the blocked pool-VOL is an external volume, use Normal Format when formatting the volume. You can decrease pool capacity for up to eight tasks at the same time.

6 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.
LUN Manager license requirements Use of LUN Manager on the P9500 storage system requires the following: • A license key on the Remote Web Console computer for LUN Manager software. For details about the license key or product installation, see the HP P9000 Remote Web Console User Guide. LUN Manager rules, restrictions, and guidelines Rules • In a fibre channel environment, up to 2,048 LU paths can be defined for one host group and up to 2,048 LU paths can be defined for one port.
Configuring fibre channel ports Configuring fibre channel ports includes the following tasks: • “Setting the data transfer speed on a fibre channel port” (page 130) • “Setting the fibre channel port address” (page 131) • “Setting the fabric switch” (page 132) • “Setting fibre channel topology” (page 133) 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 transf
Setting the fibre channel port address When configuring your storage system, set addresses for fibre channel ports. When addressing fibre channel ports, use AL-PA (arbitrated-loop physical address) or loop IDs as the addresses. See “Addresses for fibre channel ports” (page 131) for information about available addresses. NOTE: In Fibre Channel over Ethernet networks, you do not need to set the address of a fibre channel port. 1. 2. 3. 4. 5. 6. 7. In the Storage Systems tree, click Ports/Host Groups.

FC-AL or point-to-point should be used. Some fabric switches require you to specify point-to-point to get the system running. If no fabric switch is used, specify FC-AL. NOTE: In Fibre Channel over Ethernet networks, Connection Type is fixed to P-to-P. Therefore, you do not need to set Connection Type.
Configuring hosts includes the following tasks: • “Host mode options” (page 135)) • “Creating a host group and registering hosts in the host group” (page 139)) Configure hosts workflow 1. 2. 3. 4. Determine the host modes and host mode options you will use Determine the WWN of the host bus adapters that you will use. Create host groups Register host groups Host modes for host groups The following table lists the host modes that are available for use on the P9500 storage system.
CAUTION: • Note the following when setting the host mode. If Windows server hosts are registered in a host group, ensure that the host mode of the host group is 0C Windows or 2C Windows Extension. If the host mode of a host group is 0C Windows and an LU path is defined between the host group and a logical volume, the logical volume cannot be combined with other logical volumes to form a LUSE volume (an expanded LU).

Procedure 22 To create host groups and register hosts in host groups 1. 2. 3. Open the Create Host Groups window by doing one of the following: • In Remote Web Console, select General Tasks > Create Host Groups. • Select Actions > Port/Host Groups > Create Host Groups. • In the Storage Systems tree, click Ports/Hosts Groups. In the next window, select the Host Groups tab, and then click Create Host Groups.
Configure LU paths workflow Defining LU paths includes the following tasks: • “Defining LU paths” (page 141) • “Setting a UUID” (page 141) • “Defining alternate LU paths” (page 143) Defining LU paths In a fibre channel environment, you must define LU paths and associate host groups with logical volumes. For example, if you associate a host group consisting of three hosts with logical volumes, LU paths are defined between the three hosts and the logical volumes.
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.
4. Select the LUNs tab. Information about LU paths associated with the selected host group appears. 5. 6. 7. Select one or more logical units to which volumes are assigned (if a volume is assigned to a logical unit, the columns on the right of the LUN column are not empty). Select Copy LUN Paths. In the Copy LUN Paths window, select the host group to which you want to paste paths from the Available Host Groups table, and then click Add. The selected host groups appear in the Selected Host Groups table.
6. 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. If you delete many paths at one time, the deletion process may take time and the dialog box may seem to hang temporarily. Clearing a UUID setting You can clear the UUID setting that has been set to identify a logical volume from the host. 1.
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 fibre channel switches: • “User authentication” (page 148) • “Fibre channel authentication” (page 154) • “Fibre channel port authentication” (page 157) • “Setting fibre channel port authentication” (page 157)) • “Registering user information on a fibre channel port” (page 158)) • (see “Registering user information on a fibre channel switch” (page 158)) • “Clearing fibre channel swi
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.
Authenticating hosts (Cases A, B, and C) The following cases describe the examples of performing authentication of host groups Case A - The user information of the host is registered on the host group, and authentication of the host is enabled. 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.
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.
If the fibre channel switch of the port is not configured for authentication with CHAP, the authentication fails and the fibre channel switch cannot connect to the storage system. • If the user information of the fibre channel switch is registered on the port, but authentication of the fibre channel switch is disabled (Case B) Each port does not perform authentication of the fibre channel switch.
Mutual authentication of ports If mutual authentication is required, when authentication of a host is successful, the host in return authenticates the port. In authentication of ports, when user information (user name and secret) specified on the port side matches with that stored on the host, the host allows the host group to connect. Fibre channel authentication Enabling or disabling host authentication on a host group You can specify whether to authenticate hosts on each host group.
3. In the Port tree, select a port or host group on which you want to register user information of a host. The user information of hosts currently registered on the selected port or host group appears in the Authentication Information (Host) list below the Authentication Information (Target) list. You can register user information of a host even if the port status is the registered user information of a host is ignored. 4. 5. .

7 Troubleshooting Information is provided here for troubleshooting problems you may have when provisioning your storage system. If a failure occurs while your operating and a message appears, see the HP P9000 Remote Web Console Messages .for further instructions. For problems and solutions regarding to using Remote Web Console, see the HP P9000 Remote Web Console User Guide. Troubleshooting VLL If a failure occurs while you are operating, see the HP P9000 Remote Web Console Messages.
Problems Causes and Solutions Cannot create a THP V-VOL. Causes: • Usage of the pool has reached to 100%. • Something in the storage system is blocked. • Too many THP V-VOLs are assigned, or Subscription Limit is too low. Solutions: • Add some pool-VOLs to the pool. See “Increasing pool capacity” (page 111). • Increase the value of Subscription Limit for the pool. See “Changing the pool subscription limit ” (page 107). • Ask the 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 the 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 discard zero data in a THP V-VOL. Causes: • Zero data in the THP V-VOL cannot be discarded 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 V-VOL” (page 118). The THP V-VOL cannot be released though zero data in the THP V-VOL is discarded.
