Disk Drives: Monitoring and Recovery
HP Integrity NonStop NS-Series Operations Guide—529869-001

Monitoring Disk Drives With SCF
2. Get information about a disk with SCF STATUS DISK, DETAIL. For example:
-> STATUS DISK $DATA09, DETAIL
The output from this example shows that $DATA09 is in the STOPPED state,
HARDDOWN substate.
3. See Recovery Operations for a Down Disk or Down Disk Path on page 10-14.
Examples
To display the summary status of the disk $DATA01:
-> STATUS $DATA01
To display the summary status of the mirror disk of the volume $DATA02:
-> STATUS $DATA02-M
