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.
Stopping a Disk With the ABORT DISK Command
The “ABORT DISK Command” (page 193) stops access to a disk when the disk or path to the disk
either:
• Is malfunctioning but has not been brought down by the disk
• Must be removed from the system (but the system currently cannot be reconfigured)
Considerations for ABORT DISK
• Do not used the ABORT DISK, FORCED option on the system disk.
• Do not abort a volume that has open object files or swap files for currently executing processes.
First close these files by stopping the processes that are using them.
• If you omit the FORCED option and the volume has files open, SCF asks you to confirm the
abort request.
• If you omit the FORCED option when aborting the last available path, SCF asks you to confirm
the request before it aborts that path.
• You cannot abort a disk containing active TMF trails.
• When the last path to a disk is stopped, an implicit refresh operation is also performed. The
refresh operation is a general cleanup operation to prevent the device from having any
changed buffers or file control blocks still outstanding.
• Before restarting the process, you must use the “RESET DISK Command” (page 271). The ABORT
command leaves configured device paths in the STOPPED state, substate HARDDOWN. The
process remains in the system configuration database file. Any attempt to access a path that
is in the STOPPED state, substate HARDDOWN, fails with file-system error 66.
Aborting a Disk
When finished, the disk is in the STOPPED state, substate HARDDOWN.
Check the state of the disk:
-> STATUS $AUDIT
1. Force the disk to stop:
-> ABORT $AUDIT
2. Confirm that the disk is in the STOPPED state, substate HARDDOWN:
-> STATUS $AUDIT-*
STORAGE - Status DISK \COMM.$AUDIT-*
