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 14-126. 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
