Note: An error message is displayed if you try to configure more priority groups
than the adapter supports. The “Max Configurable PGs” field in the ETS
Priority Groups area shows the number of priority groups supported by the
adapter.
Changing WWN Configuration for an FC Port
The Maintenance tab enables you to change the WWPN and the WWNN of a selected
adapter port. For example, you might want to use an installed adapter as a standby if
another installed adapter fails. By changing the standby adapter's WWPN or WWNN,
it can assume the identity and configuration (such as driver parameters and persistent
binding settings) of the failed adapter.
There are three options for referencing WWNs:

Factory default WWN – The WWN as shipped from the factory.

Non-volatile WWN – The values that are saved in the non-volatile adapter’s
flash memory that survive a reboot and/or power outage.

Volatile WWN – A temporary value that is saved in the volatile memory on the
flash. If volatile WWNs are set, they are used instead of the non-volatile WWNs.
Volatile WWN changes require a warm system reboot to take effect. Volatile
WWN changes are lost on systems that power cycle the adapters during the
reboot.
