Stopping a Magnetic Disk
Stopping a Magnetic Disk
These two commands stop access to a magnetic disk:
STOP DISK command—stops access in an orderly manner
ABORT DISK command—stops access immediately
Stopping a Disk With the STOP DISK Command
The STOP DISK Command (page 14-130) stops access to a magnetic disk in an
orderly manner. When finished, the disk is in the STOPPED state, substate DOWN.
The disk remains configured in the system configuration database.
Considerations for STOP DISK
To determine the current status of disk paths you want to stop, use the STATUS
DISK command.
If you attempt to stop a disk and the backup disk path is detected as being
unavailable, the disk is not stopped.
If you do not use the FORCED attribute, SCF asks you to confirm any request to
stop a disk when it is the last path to that volume.
When the last path to a magnetic disk is stopped, an implicit refresh operation is
performed.
TMF considerations:
°
You cannot stop all paths to a disk enabled by TMF.
°
You cannot stop a volume containing active audit trails.
You cannot stop the last path to the system disk.
Stopping a Disk
1. Check the state of the disk:
-> STATUS $AUDIT
2. Stop the disk:
-> STOP $AUDIT
3. Confirm that the disk is in the STOPPED state, substate DOWN:
-> STATUS $AUDIT
If the STOP command does not work and you need to stop the disk, use the ABORT
command.
