Changing the Volume Name and Alternate Volume
Name
•
You cannot rename a disk that resides in a storage pool. If you do, the pool
process and virtual disks are not informed of the name change. Therefore, before
letting you rename a magnetic disk in a storage pool, the storage subsystem
manager issues a warning regarding the possible effects on the storage pool
process and virtual disks.
•
During system load or a START DISK command, the storage subsystem uses the
default volume name to bring up the disk. However, if the default volume name is
already in use, the alternate volume name is used. If the alternate volume name is
also in use, the volume name as recorded in the system configuration database is
used.
If both the default and alternate names are already being used, you can resolve
duplicate name conflicts by using one of these SCF commands to assign a new
name that is not in use:
°
RENAME DISK
°
ALTER DISK, VOLNAME
°
ALTER DISK, ALTNAME
These commands let you rename and bring up a disk volume that has the same
name as another volume currently active on the system. For more details, see
Naming a Magnetic Disk on page 6-26.
Renaming a Disk
1. Stop the disk you want to rename:
-> STOP DISK $DATA00
2. Verify the disk is stopped:
-> STATUS $DATA00
If the disk is not stopped, you can use the STOP command with the FORCED
attribute:
-> STOP $DATA00, FORCED
3. Rename the disk:
-> RENAME DISK $DATA00, $SPARE00
The disk volume is automatically started with the new names, $SPARE00-P and
$SPARE00-M, even if AUTOSTART is not configured.
4. Verify the volume name of the disk has changed:
-> STATUS $SPARE00
5. View the new volume name and alternate volume name:
-> INFO $SPARE00, LABEL
