WWN HAS
CHANGED
This controller was replaced in
the past and assumed the WWN
(node and port) of the original
controller. However, both con-
trollers have rebooted, and this
controller is now using a WWN
based on its own serial number.
This transition takes place on a
dual controller reboot because it
is not advisable to assume
another controllers WWNs in-
definitely (in case that controller
is repaired and plugged back in-
to the same fabric), and be-
cause host operations have
already been disrupted by the
dual boot.
Recommended
Action
Verify the WWN information for
this controller on all hosts that
access it.
NON-NATIVE
WWN
This replacement controller has
assumed the WWN (node and
port) of the original controller.
This is done to make the re-
placement of a controller in an
active-active configuration trans-
parent to the host. However, if
both controllers lose power or
are otherwise rebooted, the ori-
ginal controllers WWN will be
lost, and the current controller
reboot will cause the controllers
WWN to change from the hosts
perspective.
Verify the WWN information for
this controller on all hosts that
access it.
