Working with SPM groups
You can use Server Priority Manager to create SPM groups to manage multiple host bus adapters as a single group. Each SPM group can contain up to 32 HBAs, and you can create up to 512 SPM groups in the storage system. All HBAs in an SPM group have the same priority. Prioritized WWNs and non-prioritized WWNs cannot be mixed in the same group.
You can use an SPM group to switch priority of multiple HBAs from prioritized to non-prioritized, or vice versa. You can also use an SPM group to set the same upper limit value to all HBAs in the group.
