Recovery Operations for a Down Disk or Down Disk Path
To restart a disk or disk path:
1. If a path is down due to a ServerNet fabric failure, determine the affected paths.
From an SCF prompt:
-> STATUS DISK $*-*, SUB MAGNETIC
The output indicates:
•
$DATA06-M and $DATA06-MB are stopped in the DOWN substate.
•
$WD8-M and $WD8-MB are stopped in the HARDOWN substate.
•
$DATA00-P and $DATA00-B are stopped in the HARDDOWN substate.
2. Reset disk drives that are in the HARDDOWN substate. At an SCF prompt:
-> RESET DISK $volume
For example:
-> RESET DISK $WD8
Resetting a disk in the HARDDOWN substate places it in the DOWN substate.
3. Restart the disk. At an SCF prompt:
-> START DISK $volume
If the disk does not start, the disk might need replacement. If neither half of a mirrored
volume starts, the database might need recovery. Contact your service provider.
