Volume allocation methods
When you allocate volumes, you can use the Allocate Volumes dialog box or the Define Clustered-Host
Storage dialog box.
Begin by selecting resources, such as volumes or hosts, and then click Allocate Volumes, which opens
the Allocate Volumes dialog box.
Click Allocate Volumes without first selecting a resource, such as a volume or host.
There are multiple methods in which to begin allocating volumes. The visible fields in the Allocate
Volumes dialog box will vary depending on the starting point and whether you have selected a
resource to begin the procedure. For example, if you select resources first, the Allocate Volumes dialog
box will prompt you for less information.
When using the Allocate Volumes dialog box, the following conditions apply when you begin volume
allocation using these available methods and starting points:
•
From the General tasks pane
On the Resources or Mobility tab, from General Tasks, click Allocate Volumes. Because no resource
was selected first, you must specify host, volume, and other volume allocation requirements.
•
Selecting hosts
From the Resources tab, select one or more hosts, and click Allocate Volumes. The dialog will
display the selected host names instead of prompting.
•
Selecting volumes
From the Resources tab, select one or more volumes, and click Allocate Volumes. The dialog will
prompt for host 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 desired attributes and criteria for the
new volume allocation, and click Allocate Like Volumes.
When using the Define Clustered-Host Storage dialog box, 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.
