Note: If the array subsystem connected to the NAS Unit is restarted, the cluster between the
NAS Units stops. When the array subsystem is unavoidably restarted, execute it after
stopping the cluster between the NAS Units and stopping the NAS OS of both NAS Units. Start
the cluster between the NAS Units again after completing the restart for the array subsystem.
Note: There is a case where a NAS system cannot be accessed from a host computer even
though the READY LED of NAS unit illuminates. A NAS system accepts access from a host
computer only in case of "ACTIVE" NAS OS Condition.
