Deleting disk pool
Use the Delete option to delete a disk pool and all the virtual disks in the disk pool. When a disk pool is deleted, the physical disks that
were associated with the disk pool change to the Unassigned state. This process creates more unconfigured capacity in the storage
array, which you can reconfigure to meet your storage needs.
CAUTION: Possible loss of data access – Deleting a disk pool causes loss of all data on the virtual disks in the disk pool.
Before performing this operation, back up the data on all the virtual disks in the disk pool, stop all input/output (I/O),
and unmount any file systems on the virtual disk.
Keep these guidelines in mind before you delete a disk pool:
• If you delete a disk pool that contains a snapshot repository virtual disk, you must delete the base virtual disk before you delete the
associated snapshot virtual disk.
• The capacity from the physical disks that were previously associated with the deleted disk pool is added to either of these nodes:
○ An existing Unconfigured Capacity node.
○ A new Unconfigured Capacity node if one did not exist previously.
• You cannot delete a disk pool that has any of these conditions:
○ The disk pool contains a repository virtual disk, such as a snapshot group repository virtual disk, a replication repository virtual disk,
or a Consistency Group member repository virtual disk. You must delete the logical component that has the associated repository
virtual disk in the disk pool before you can delete the disk pool.
NOTE: You cannot delete a repository virtual disk if the base virtual disk is in a different disk pool and you have
not requested to delete that disk pool at the same time.
○ The disk pool contains a base virtual disk or a target virtual disk participating in a virtual disk copy operation with the status of In
Progress.
To delete a disk pool:
1. Select the Storage & Copy Services tab.
2. Select one or more disk pools.
3. From the menu bar, select Storage > Disk Pool > Delete.
The Confirm Delete Disk Pool dialog is displayed.
4. Type yes to confirm, and click OK.
The Delete Disk Pool - Progress dialog is displayed while all the virtual disks in the disk pool are being deleted.
Viewing storage array logical components and
associated physical components
You can view the logical components (virtual disks , disk pools, and disk groups) in a storage array, and then view the physical components
(RAID controller modules, RAID enclosures, physical disks, and expansion enclosures) that are associated with a specific logical
component.
1. To view the components, select the Storage & Copy Services tab.
The object tree is displayed on the left, and the Properties pane is displayed on the right. The object tree provides a view of the
components in the storage array in a tree structure. The components shown include the disk pools, the disk groups, the virtual disks,
the free capacity nodes, and any unconfigured capacity for the storage array. The Properties pane displays detailed information about
the component that is selected in the object tree.
2. To view the physical components that are associated with a component, perform one of these actions:
• Right-click a component, and select View Associated Physical Components.
• Select a component, and click View Associated Physical Components in the Properties pane.
• Select a component, and from the menu bar, select Storage > Disk Pool > View Associated Physical Components.
The associated physical components are displayed with a blue circle.
