NOTE: When connecting the Fibre Channel interface cables, insert the
cables until they are secure with the host connectors. If the cables are
inserted half into the host connectors, the controller continues to detect the
Fibre Channel failures and I/O processing may deteriorate.
NOTE: The controller usually recovers in about three minutes; however, if
I/O from the host is high, it may take up to 30 minutes to recover.
