Adding Unassigned Physical Disks To A Disk Pool
Use the Add Physical Disks (Capacity) option to increase the free capacity of an existing disk pool by adding unassigned
physical disks. After you add unassigned physical disks to a disk pool, the data in each virtual disk of the disk pool is
redistributed to include the additional physical disks.
NOTE: Keep these guidelines in mind when you add physical disks to a disk pool:
• The status of the disk pool must be Optimal before you can add unassigned physical disks.
• You can add a maximum of 12 physical disks to an existing disk pool. However, the disk pool cannot contain
more physical disks than the maximum limit for a storage array.
• You can add only unassigned physical disks with an Optimal status to a disk pool.
• The data in the virtual disks remains accessible during this operation.
To add unassigned physical disks a disk pool:
1. In AMW, select the Storage & Copy Services tab.
2. Select the disk pool.
