Grouping HBAs
XP Performance Control allows you to create a Performance Control group to contain multiple HBAs.
All the HBAs in one Performance Control group must be of the same priority. Prioritized WWNs (that
is, high-priority HBAs) and non-prioritized WWNs (that is, low-priority HBAs) cannot be mixed in the
same group.
You can use a Performance Control group to switch priority of multiple HBAs from prioritized to
non-prioritized, or vice versa. You can also use a Performance Control group to set the same upper-limit
value to all the HBAs in the group.
This section describes the operations that can be performed with Performance Control groups.
• Containing Multiple HBAs in a Performance Control Group
• Deleting an HBA from a Performance Control Group
• Switching Priority of a Performance Control Group
• Setting an Upper-Limit Value to HBAs in a Performance Control Group
