Error
In dual-controller

removed.
Action
If the MSA is currently
involved in host I/O, remove
the standby array controller,
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, and reinsert
them, ensuring they are fully
seated in the chassis.
Should the issue persist,
contact HP support.
Reinsert the missing array
controller ensuring that it is
fully seated in the chassis.
Remove the array controller
that has been halted, replace
the cache modules with the
appropriately sized ones,
wait 10 seconds, and then
reinsert the array controller,
ensuring that it is fully seated
in the chassis.
Remove the other array
controller for the planned
service. When complete,
reinsert the array controller,
ensuring that it is fully seated
in the chassis.
