Configuring the Storage Pool Policy
VLS automatically creates storage pools on the VLS arrays in the system based on your storage
pool policy. Storage pools are defined in terms of whole arrays (one base enclosure and three
capacity enclosures). Use the Storage Pool Policy Wizard to set the storage pool width across the
arrays in the system.
To set the storage pool policy from Command View VLS:
1.
Select the System tab.
2.
Select Storage Pools in the navigation tree.
3.
From the task bar, select Edit Policy. The Storage Pool Policy Wizard screen is displayed.
4.
Select the number of arrays wide in the Number of Arrays Wide field. You can select “All”
for one storage pool across all arrays, or select 1–8 for that many arrays per storage pool.
Only the Number of Arrays Wide default value can be changed.
5.
Click Next.
6.
Click Next to confirm.
If the existing storage pools do not fit into the new storage pool policy selected, a dialog box
will ask if you want to erase the existing storage pools to create the new policy. Select Yes to
rebuild all storage pools or No to cancel the change. See
.
7.
Click Finish.
Viewing the Storage Pool
To view the storage pool information from Command View VLS:
1.
Select the System tab.
2.
Expand Storage Pools in the navigation tree.
3.
Select the storage pool of interest in the navigation tree. The storage pool details window
opens.
Rebuilding all Storage Pools
To delete all information on the VLS9200 arrays and reformat them, perform a Rebuild All Storage
Pools from Command View VLS.
CAUTION:
Rebuild All Storage Pools destroys all current virtual tape cartridges in the system.
To rebuild all storage pools from Command View VLS:
1.
Select the System tab.
2.
Select Storage Pools in the navigation tree.
3.
Select Rebuild All Storage Pools from the task bar.
4.
Select Rebuild, or, if your system has deduplication enabled, select Restart Emulations in
Maintenance Mode from the task bar.
Systems with deduplication enabled must enter Maintenance Mode before rebuilding the
storage pools. Maintenance Mode reboots the system with deduplication disabled and the
front fibre ports down.
5.
If your system has deduplication enabled, wait until the system has completed rebooting into
Maintenance Mode, then follow steps 1 through 3. The system will reboot again; when the
system is back up, deduplication is enabled and the front fibre ports are back up.
