Deleting a Magnetic Disk
Deleting a Magnetic Disk
The DELETE DISK Command (page 14-76) removes a magnetic disk from the system
configuration database.
Considerations for DELETE DISK and Magnetic Disks
•
A disk volume must be STOPPED or not running before you can delete it.
•
You can delete a mirror half of a disk volume while the disk volume is in a
STARTED state.
•
You cannot delete only the primary half of a mirrored volume.
•
Deleting the mirror volume also deletes the mirror backup, if it exists.
•
Always note the location of the disk that you delete. Once you delete a disk from
the system configuration database, it becomes unavailable to SCF. However:
•
Installing an unconfigured disk in a slot generates an error message either at
that time or when the system is restarted.
•
You can use OSM or TSM to view disks that are physically currently installed in
system slots. For more information, see the OSM or TSM online help for more
information.
For additional details, see Displaying Information About Installed, Nonconfigured
Internal Disks on page 5-2.
•
Issue a START command to restart the IOP after deleting the mirror volume.
Example
1. Stop any new disk activity:
-> STOPOPENS $DATA14
2. Stop the disk:
-> STOP $DATA14
If any files on the disk are currently open, they are identified in the return message.
3. Delete $DATA14 from the system configuration database:
-> DELETE $DATA14
4. Confirm that the disk has been deleted:
-> INFO $DATA14
