Configuring the Storage Pool Policy

VLS automatically creates storage pools on the VLS9000 arrays in the system based on your storage
pool policy. Storage pools are defined in terms of whole arrays (one base disk array and three
expansion disk arrays). Use the Storage Pool Policy Wizard to set the storage pool width across the
arrays in the system:
• All (default)—One storage pool across all arrays
• 1—One storage pool across each array
• 2—One storage pool across every two arrays
• 4—One storage pool across every four arrays
Partially-populated storage pools may result if storage pool policy 2 or 4 is selected. For example, if
the storage pool policy is 2 and there are three arrays in the system, the VLS divides the three arrays
into two storage pools. One storage pool spans across two arrays, and the other storage pool spans
across one array. If a fourth array is added, the VLS automatically adds it to the storage pool with
only one array.
To set the storage pool policy:
1. Open a Command View VLS session and log in as the administrator. See
"Opening a Command View VLS Session from a Web
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 and then click Next.
Only the Number of Arrays Wide default value can be changed.
5. 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
rebuilt all storage pools or No to cancel the change. See
6. Click Finish.
