After checking the RAID Manager XP configuration definition file, stop RAID Manager XP in both the NAS

Cascade configuration of Continuous Access XP Journal and Business Copy XP
In the NAS Blade system, you can use the Continuous Access XP Journal and Business Copy XP pair file
systems in a cascade configuration. In a cascade configuration, you can prepare for disaster scenarios
where, for example, you cannot recover the file system from the Continuous Access XP Journal S-VOL by
backing up the file system copied from the Continuous Access XP Journal P-VOL to S-VOL periodically using
Business Copy XP.
