Considerations for Adding a Magnetic Disk to a Storage
Pool
•
All the magnetic disks in a storage pool must be on the same system.
•
Up to 144 magnetic disk volumes can be placed in a pool.
•
A magnetic disk volume can be in only one storage pool at a given time.
•
When you add a magnetic disk to a storage pool:
°
The magnetic disk must be in the STARTED state.
°
The POOL object must be the STARTED state.
°
The magnetic disk cannot be a member of another storage pool.

Considerations for Removing a Magnetic Disk From a
Storage Pool
When you remove a magnetic disk from a storage pool:
•
The POOL name is removed from the disk label if the pool process for the disk is
not defined in the system.
•
SCF asks you to confirm the command in these cases:
°
The POOL process for the disk is not in the STARTED state.
°
Virtual disks associated with the pool are not in the STARTED state.
°
The physical volume has storage-managed files on it.
