Continuous Access XP Journal user guide 159
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 RAID Manager XP configuration definition file, HP recommends creating a file system
to be temporarily paired before executing the mkconf.sh command. After creating the RAID Manager XP
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 ”Create file systems in Continuous Access XP Journal P-VOLs” on page 168. You must delete
the temporarily created file system in the secondary site before creating a file system pair.
The following explains how to create a RAID Manager XP configuration definition file in the NAS package
in CL1 in the primary site in the sample configuration above. You must create RAID Manager XP
configuration definition files for the other three NAS packages using the previously explained procedure.
Creating a template for a RAID Manager XP configuration definition file
Figure 74 shows an example of how to create a template for a RAID Manager XP configuration definition
file.

Editing the template for the RAID Manager XP configuration definition file
Table 29 lists the values specified for items included in the RAID Manager XP configuration definition file
in the NAS Blade system.
