You must perform these operations in each NAS package in CL1 and CL2 where the XP Continuous
Access Journal P-VOL is connected and in each NAS package in CL1 and CL2 that uses the S VOL.
Therefore, you must prepare a total of four XP RAID Manager configuration files, assuming one
instance per NAS package. For two instances, you need a total of eight configuration files.
In NAS Blade, you can define one or two XP RAID Manager instances per NAS package. To
operate only the XP Continuous Access Journal pairs in XP RAID Manager, you need one instance.
To operate pairs where XP Continuous Access Journal and XP Business Copy are cascaded, you
need two instances.
The following section explains how to create an XP RAID Manager configuration definition file
using the NAS Blade system with LUs as an example (see
).

Add the
HORCM_DEV
and
HORCM_INST
sections to the template of the XP RAID Manager
configuration definition file using the
mkconf.sh
command in XP RAID Manager.

$ cat /home/nasroot/horc_devfile | sudo mkconf.sh -gg Device Group Name -i 16 -a
CAUTION:
If you execute the
mkconf.sh
command without specifying the
-a
option, the
HORCM_MON
and
HORCM_CMD
sections in the XP RAID Manager configuration definition file that
are automatically created when NAS Backup Restore is installed are overwritten. In this case,
delete all lines above the
HORCM_MON
section, and change the entry service in the
HORCM_MON
section to an appropriate value based on
To execute the
mkconf.sh
command, the LU constituting the file system to be paired must be
attached to the NAS OS. The LU configuration (size and number) in the file system to be paired
must be exactly the same in the primary and secondary sites.
To create the correct XP RAID Manager configuration definition file, HP recommends creating a
file system to be temporarily paired before executing the
mkconf.sh
command. After creating
the XP RAID Manager configuration definition file using the
mkconf.sh
command, you can
continue using the file system in the primary site. Alternatively, you can delete it and create a file
system with the same configuration using the same LU in
