PRIMARY SUBSYS Command
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:
OUT file-spec
directs all SCF output to the specified file.
SUBSYS $ZZSTO
is the storage subsystem manager.
cpunumber
is the processor number of the processor that you want to move storage
subsystem IOPS into or away from.
AWAY
specifies that all storage subsystem IOPs currently running their primary processes
in cpunumber be moved away from that processor.
DEFAULT
specifies that all running storage subsystem IOPs that are configured with
cpunumber as their PRIMARYCPU be moved into that processor, and that all
running storage subsystem IOPs that are configured with cpunumber as their
BACKUPCPU be moved away from that processor.
PRIMARY SUBSYS Examples
•
To move all storage subsystem IOPs in the group 02 topology branch away from
processor 3:
-> PRIMARY SUBSYS $ZZSTO, 3, AWAY
•
To move all storage subsystem IOPs configured with PRIMARYCPU 2 to that
processor:
-> PRIMARY SUBSYS $ZZSTO, 2, DEFAULT
PRIMARY TAPE Command
The PRIMARY TAPE command switches the primary and backup processors for the
specified tape drive. The current primary process becomes the backup process, and
