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

SUB { ALL | MAGNETIC | VIRTUAL } specifies that the command affects only disks of the
specified type. The default is ALL.
See “Attribute Descriptions for Disk Commands” (page 198) for descriptions of all attributes for disk
commands.
PRIMARY DISK Examples
See the procedure for “Swapping Processors for a Disk” (page 109).
• To run the primary disk process in processor 3:
-> PRIMARY $DATA00, 3
• To swap the primary and backup processors controlling a disk:
-> PRIMARY $SYSTEM
• To switch the primary and backup processors controlling two disks:
-> PRIMARY ($DATA01, $DATA02)
PRIMARY MON Command
The PRIMARY MON command swaps the primary and backup processors for the MON process.
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 / ] MON $ZSMS [ , cpunumber ]
Wild-card characters are supported.
MON $ZSMS
is the SMF master 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 MON Examples
See the procedure for “Swapping Processors for the SMF Master Process” (page 47).
• To run the primary process of $ZSMS in processor 3:
-> PRIMARY $ZSMS, 3
• To swap the primary and backup processors controlling $ZSMS:
-> PRIMARY $ZSMS
PRIMARY POOL Command
The PRIMARY POOL command swaps the primary and backup processors for the specified storage
pool process. 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 / ] POOL $pool [ , cpunumber ]
Wild-card characters are supported.
