51 REDUNDANCY
FAILED I/O
REQUEST ERROR Error While either attempting
to enter redundant mode
or already operating in
redundant mode, one of
the array controllers
encountered an error
while sending I/O
between the two array
controllers over the
communication channel
between them.
Redundancy is disabled
at this time.
If the MSA500 system is
currently involved in host
I/O:
1. Remove the standby
array controller.
2. Wait 10 seconds.
3. Reinstall the controller,
and be sure that it
seats fully in the
chassis.
If this action does not solve
the problem, wait until
downtime is available and
do the following:
1. Power down the
MSA500 system.
2. Remove both array
controllers.
3. Reinstall both array
controllers, and be sure
that they seat fully in
the chassis.
If this action does not solve
the problem, contact HP
support.
