Grouping host bus adapters
Use XP Performance Control to create a PFC group that contain multiple host bus adapters. All host bus
adapters (HBAs) in one PFC group must be of the same priority. Prioritized WWNs (for example,
high-priority HBAs) and non-prioritized WWNs (for example, low-priority HBAs) cannot be mixed in one
PFC group.
You can use a PFC group to switch the priority of multiple HBAs from prioritized to non-prioritized, or vice
versa. You can also use a PFC group to set the same upper limit value to all HBAs in the group.

Control pane appears.
