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” (page 123).
