Displaying Current Status Information
The STATUS SUBSYS Command (page 14-127) displays current information about the
storage subsystem manager:
-> STATUS SUBSYS $ZZSTO
Using the PRIMARY SUBSYS Command
The PRIMARY SUBSYS command replaces a series of PRIMARY commands for
individual IOPs in the topology branch. The PRIMARY SUBSYS command does not
start any processes.
At the completion of the command, the PRIMARY SUBSYS command returns a list of
the IOPs that did not move the primary IOP. You must handle any exceptions
individually.
On G06.10 and earlier RVUs, a primary processor change by one disk IOP might
cause other disk IOPs to lose controller ownership and thus cause those other disk
IOPs to perform primary changes. See Guidelines for G06.10 and Earlier RVUs on
page 8-6.
BulkIO shows whether direct bulk I/O is on or off.
LabelTape shows whether labeled-tape operation is on or off.
UPS shows whether the uninterruptible power supply option is on or off.
Note. M8xxx disks are described in Types of Magnetic Disks on page 6-2
