issuing the horc_devlist command in the NAS package in which the S-VOL is used. Compare this
with Figure 80.
Figure 82 Checking device file and LDEV numbers for unused device files that can be S-VOLs
Table 31 lists port names described in the HORCM_DEV section in the RAID Manager XP configuration
definition file and the locations of the NAS packages.
After checking the RAID Manager XP configuration definition file, stop RAID Manager XP in both the NAS
package in which the Continuous Access XP Journal P-VOL is connected and in the NAS package in which
the S-VOL is used (see Figure 83).
Figure 83 Stopping RAID Manager XP (for instance number 16)
Manually save the NAS OS LU to save the configured RAID Manager XP configuration definition files. For

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.
