Changing the priority of an SPM group

All host bus adapters in one SPM group must have the same priority. Prioritized WWNs and non-prioritized WWNs cannot be mixed in one SPM group.

You can use an SPM group to change the priority of multiple HBAs between prioritized and non-prioritized.

You can perform the upper-limit value control for an SPM group by setting the upper-limit value on the SPM group. For more information, see Working with SPM groups.
