Stopping a Magnetic Disk With the ABORT DISK
Command
Stopping a Magnetic Disk With the ABORT DISK Command
The ABORT DISK Command (page 14-5) stops access to a magnetic 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 on
page 14-104. 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.
1. Check the state of the disk:
-> STATUS $AUDIT
2. Force the disk to stop:
-> ABORT $AUDIT
