Resetting a Virtual Disk
Resetting a Virtual Disk 
The RESET DISK Command (page 14-126) puts a virtual disk into the STOPPED 
state, substate DOWN, ready to be started. 
1. Check the current status of the disk:
-> STATUS $VDISK00 
2. If the disk is in the HARDDOWN state or SERVICING state, substate SPECIAL: 
-> RESET $VDISK00 
3. Start the disk:
-> START $VDISK00
4. Confirm that the disk is started:
-> STATUS $VDISK00 
Stopping a Virtual Disk 
The STOP DISK Command (page 14-148) stops access to a virtual disk. Although you 
can use ABORT DISK for virtual disks, the command that is actually executed is the 
STOP DISK command. When the STOP DISK command finishes, the disk is left in a 
STOPPED state, substate DOWN and remains configured in the system configuration 
database. 
Example
1. Check the state of the disk: 
-> STATUS $VDISK00 
2. Stop the disk:
-> STOP $VDISK00
3. Confirm that the disk is in the STOPPED state, substate DOWN:
-> STATUS $VDISK00 
Swapping Processors for a Virtual Disk 
The PRIMARY DISK Command (page 14-116) swaps the primary and backup 
processors for a virtual disk. The current primary processor becomes the backup 
processor, and the backup processor becomes the primary processor, but the 
PRIMARYCPU and BACKUPCPU values stay the same.  You typically swap 
processors when load balancing the system or preparing for disk replacement.
