Hitachi Command Suite 8 User Guide

							• From the General tasks paneOn the Resources or Mobility tab, from General Tasks, click AllocateVolumes. Because no resource was selected first, you must specify host,
volume, and other volume allocation requirements.
• Selecting hosts or file servers From the Resources tab, select one or more hosts or file servers, and clickAllocate Volumes. The dialog will display the selected host or file server
names instead of prompting.
• Selecting volumes From the Resources tab, select one or more volumes, and click AllocateVolumes. The dialog will prompt for host or file server name, but will not
prompt for volume criteria.
• Selecting clustered hosts Configuring clustered hosts in a logical group helps ensure that volume
allocations will be consistent for all members of the cluster. From the Resources tab, select a logical group, select all host members of the group,
and then click Allocate Volumes. If clustered hosts are not in a logical
group, from General Tasks or Actions, click Allocate Volumes and select
multiple hosts. You may also use the Resources tab to locate clustered
hosts, and then Allocate Volumes. The use of logical groups is recommended to avoid host selection errors.
• Searching for volumes You can search for volumes that meet specific criteria (such as storage
system, specific allocation status, volume type, drive type, drive speed, or
chip type), select one or more volumes from the search results, and click
Allocate Volumes.
You can also search using full or partial text keywords such as storage
system name or host name, and then allocate volumes to the selected resource. Searching eliminates the need to manually navigate to the
resource.
• Using existing volume settings From the Resources tab, select an allocated volume that has desiredattributes and criteria for the new volume allocation, and click Allocate Like
Volumes.
When using the Define Clustered-Host Storage dialog box for Fibre Channel and Fibre Channel over Ethernet (FCoE) connections, when you create a cluster configuration using existing hosts or when you add a new host to an
existing host group or cluster, allocate the same volumes that are assigned to
the existing hosts in the host group to the new host.

Suite.
If you want to select volumes from a tier, Tiered Storage Manager license must be enabled.
In addition, determine:
• The target host or file server • The volume type, count, capacity, and performance characteristics • An appropriate storage system

Tip: If you are linking with Hitachi NAS Platform v11.3 or later and
allocating volumes to a file server when creating or expanding storage
pools, the following is recommended: Use the  Create Storage Pool
dialog box or the  Expand Storage Pool  dialog box instead of the
Allocate Volumes  dialog box to create or expand storage pools and
allocate volumes at the same time.194Provisioning storageHitachi Command Suite User Guide 
						

							Device Manager can automatically specify a volume and path
configuration for allocating volumes that follows the best practices for
configuring storage pools.Tip:  For Hitachi NAS Platform family, in cases such as node additions, if
you want to allocate volumes to file server nodes that are in clusters, use
the  Define Clustered-Host Storage  dialog box.
A completed task indicates a successful volume allocation.
9. To verify the volume allocation, select the file server or cluster to which
the volumes were allocated, and then select the  System Drives tab for
Hitachi NAS Platform family, or select the  Volumes tab for Hitachi NAS
Platform F or Hitachi Data Ingestor to confirm that the volumes were
allocated successfully.
Result
Volumes have been allocated to a file server, or file server cluster, and
verified.

Allocating volumes to clustered hosts To prevent possible errors with cluster host selection, group hosts that belong
to a cluster into a public logical group or a private logical group. Alternatively, you can select multiple hosts or file servers in the  Allocate Volumes dialog
box.
Tip:  When you create a cluster configuration using existing hosts or when
you add a new host to an existing host group or cluster, use the  Define
Clustered-Host Storage  dialog box to allocate volumes to the new host.
When using the  Define Clustered-Host Storage  dialog box, you can add
the WWN of the new host to the same host group as the WWN of the existing hosts.
Prerequisites
• Add clustered hosts into the desired logical group type.
196Provisioning storageHitachi Command Suite User Guide 
						

							• Confirm the names of the hosts that belong to the target cluster (if youhave not already added clustered hosts into a logical group).
Procedure 1. On the  Resources  tab, select  Logical Groups .
2. Expand the  Public Logical Groups  or Private Logical Groups  root
folder, and locate an appropriate logical group.
3. Locate the  Hosts and Volumes  tabs under the summary pane, and
select all hosts for the cluster.Note:  You can allocate volumes to cluster hosts that are not in a logical
group. However, you must ensure that your host selection is correct.
Logical groups are strongly recommended.
4. Click  Allocate Volumes .
Tip: To allocate volumes to cluster hosts, verify that all cluster host
names are displayed in the  Allocate Volumes dialog box to prevent an
incorrect allocation.
5. On the  Allocate Volumes  dialog box, specify volume allocation
requirements.
6. Click  Show Plan  and confirm that the information in the plan summary
is correct. If changes are required, click  Back.
7. (Optional) Update the task name and provide a description.
8. (Optional) Expand  Schedule to specify the task schedule.
You can schedule the task to run immediately or later. The default setting

If the task is scheduled to run immediately, the process begins.
10. (Optional) Check the progress and result of the task on the  Tasks &
Alerts  tab. Click the task name to view details of the task.
Result
A completed task indicates a successful volume allocation.
The same volumes have been allocated to the individual hosts that belong to
a cluster.

Allocating volumes by using a keyword search A keyword search is a full or partial text search. For example, you can search
for storage systems, hosts, volumes, parity groups, DP pools, and logical
groups by entering a full or partial name. Note that file servers are not
subject to search. Using a keyword search provides an alternate method of navigating to a resource to allocate volumes.
Procedure 1. Enter a value in the search box and press  Enter on your keyboard.  All
Resources  is the default selection criteria. You can limit the scope of
searched resources by using the drop-down menu.Note:  As the number of searchable objects grows, identify a specific
resource to search, for example  Logical Groups, to decrease search
time.
2. Click the link for appropriate resource. For example, assuming you
searched for hosts, from your search results, click the host name link.
The appropriate location in the  Resources tab is displayed. The host is
effectively selected.
