Recovery Operations for Defective Sectors
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 you cannot start a disk drive, escalate the problem. Disk replacement might be 
required. Database recovery might be required if you cannot restart either volume of a 
mirrored volume. Contact your service provider.
Recovery Operations for Defective Sectors
If you are authorized, use the SCF CONTROL DISK, SPARE command to spare 
defective sectors. For information on reinitializing the disk drive, refer to the SCF 
Reference Manual for the Storage Subsystem..
