PRIMARY MON Command
FORCED
(magnetic disks only) for G06.10 and earlier RVUs, specifies that all disk
processes using the same controller as the specified disk must switch to the
specified primary processor.
Beginning with G06.11, the FORCED attribute is ignored. Because SACs can be
owned by more than one processor, the PRIMARY command affects only the IOP
for the disk whose primary processor is being swapped. Other disk processes are
unaffected. For more details, refer to Section 7, Managing Magnetic Disks.
POOL $pool
specifies that the PRIMARY DISK command should be performed only on disks
associated with the specified storage pool.
SEL state
specifies that the command affects only devices in the specified state.
SUB { ALL | MAGNETIC | VIRTUAL }
specifies that the command affects only disks of the specified type. The default is
ALL.
PRIMARY DISK Examples
See the procedure for Swapping Processors for a Disk on page 7-24.
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:
Wild-card characters are supported.
