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 14-148) 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.
