Altering Magnetic Disk Attribute Values
Altering Magnetic Disk Attribute Values
Use the ALTER DISK Command (page 14-51) to change configured attributes for
magnetic disks.
Considerations for ALTER DISK and Magnetic Disks
To change these attributes, first put the disk in the STOPPED state by using the
STOP DISK Command (page 14-148):
If a nonmirrored disk is in STARTED state, you can add a mirror drive by altering
the appropriate MIRROR and MBACKUP path attributes.
When changing these attributes, the IOP is not forced to stop:
To change the VOLNAME or ALTNAME attributes, see Naming a Magnetic Disk on
page 6-26.
When specifying attributes to add a physical volume to a storage pool:
°
The pool process and CATALOGLOCATION volume must be in the STARTED
state.
°
The CATALOGLOCATION volume must be protected by TMF.
When using the AUTOSELECT and PHYSVOLSELECT attributes:
°
The pool process and CATALOGLOCATION volume must both be in the
STARTED state.
°
The CATALOGLOCATION volume must be enabled by TMF.
°
The physical volume must be in the STARTED state.
