Swapping Processors for a Virtual Disk
The“PRIMARY DISK Command” (page 264) 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.
Examples
• To execute the primary process of $VDISK00 in processor 3 (assuming it is configured to run
in processor 3):
-> PRIMARY $VDISK00, 3
• To make the current backup process of $VDISK00 the primary process:
-> PRIMARY $VDISK00
