SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

POOL $pool
is the storage pool process.
cpunumber
is the processor number of the processor that is to become the primary processor. This decimal
integer must identify one of the two processors configured as primary and backup processors
for the device. If you do not specify a processor number, the storage subsystem manager
determines which processors are currently being used for the primary process and backup
process and swaps those processors. If you specify the processor number of the current primary
processor, no change occurs.
PRIMARY POOL Examples
See the procedure for “Swapping Processors for a Pool Process” (page 142).
• To run the primary pool process in processor 3:
-> PRIMARY $POOL00, 3
• To swap the primary and backup processors controlling a pool process:
-> PRIMARY $POOL01
PRIMARY SCSI Command
The PRIMARY SCSI command switches the primary and backup processors for the specified Open
SCSI device. The current primary process becomes the backup process, and the current backup
process becomes the primary process, but the PRIMARYCPU and BACKUPCPU values stay the
same. The syntax is:
PRIMARY [ / OUT file-spec / ] SCSI $SCSI-device
[ , cpunumber ]
Wild-card characters are supported.
SCSI $SCSI-device
is the name of the Open SCSI device.
cpunumber
is the processor number of the processor that is to become the primary processor. This decimal
integer must identify one of the two processors configured as primary and backup processors
for the device. If you do not specify a processor number, the storage subsystem manager
determines which processors are currently being used for the primary process and backup
process and swaps those processors. If you specify the processor number of the current primary
processor, no change occurs.
PRIMARY SCSI Examples
See “Swapping Processors for an Open SCSI Device” (page 177).
• To run the primary Open SCSI process in processor 3:
-> PRIMARY $DEV0, 3
• To swap the primary and backup processors:
-> PRIMARY $DEV0
PRIMARY SUBSYS Command
The PRIMARY SUBSYS command moves all storage subsystem IOPs into or away from a processor,
as part of device or adapter replacement. The syntax is:
