Type Description
Error
Both array controllers must
contain the same hardware
for them to successfully
enter redundant mode. The
current array controllers
do not contain the same
hardware, possibly because
one has an attached Fibre
Channel daughter card and
the other does not.
Error
Both array controllers must
be running the same version
of firmware for them to
successfully enter redundant
mode. A process called
firmware cloning, which
attempts to make them both
the same firmware level,
has failed.
Informational If volume expansion is in
progress then redundancy
is not supported. Volume
expansion is initiated and
tracked using the Array
Configuration Utility (ACU).
After the volume expansion
is complete, redundancy is
automatically reestablished.
Error
Both array controllers must
have the same size of cache
memory to successfully
enter redundant mode.
Action
If the MSA is currently
involved in host I/O, remove
the standby array controller,
add or replace the Fibre
Channel daughter card as
needed, wait 10 seconds,
and then reinsert it, ensuring
that it is fully seated in the
chassis.
If this does not resolve the
issue, wait until downtime
is available. Power off the
MSA, remove both array
controllers, add or remove
Fibre Channel daughter
cards as needed on both,
and reinsert them, ensuring
they are fully seated in the
chassis.
Should the issue persist,
contact HP support.
Manually update the
firmware on the older array
controller. For instructions,
see the MSA firmware
updating guide.
