Recovery Operations for Disk Drives
Recovery Operations for Disk Drives
These SCF commands control DISK objects:
For more information, see the SCF Reference Manual for the Storage Subsystem.
Command Description
ABORT Terminates the operation of a disk drive immediately, leaving it in the
STOPPED state, HARDDOWN substate.
ALTER Changes attribute values for a storage device.
BYPASS Bypasses one or more disks in a Fibre Channel disk-drive enclosure.
CONTROL Issues disk-specific commands.
PRIMARY For a disk drive, causes the backup processor to become the primary
processor and the primary processor to become the backup processor.
RENAME Changes the name of a disk drive.
RESET Puts a disk drive in a state from which it can be restarted.
START Initiates the operation of a disk drive.
STOP Terminates the operation of a disk drive in a normal manner.
SWITCH Switches paths to a disk drive.
Table 10-3. Common Recovery Operations for Disk Drives (page 1 of 2)
Problem Recovery
Free-space
fragmentation
Use the Disk Compression Program (DCOM) to consolidate disk space.
See Disk Compression Program (DCOM)
on page B-2.
Disk full 1. Use DSAP to identify large, old, and little used files.
2. If you are authorized:
•
Use the BACKUP utility to back up these disk files to tape and then
purge them from the disk. Do not purge important system files.
•
Move files to another disk. Do not move important system files.
•
Ask users to purge files.
For more information about these utilities, see BACKUP
on page B-2 and
Disk Space Analysis Program (DSAP) on page B-2.
Down disk or
disk path
Recovery Operations for a Down Disk or Down Disk Path
on page 10-14
Defective
sectors
If you are authorized, use the SCF CONTROL DISK, SPARE command to
spare defective sectors. For information on reinitializing the disk drive, see
the SCF Reference Manual for the Storage Subsystem.
Disks come formatted from HP. No disk format utility is available. Return
any disk that requires formatting to HP.
