Continuous Access XP Journal user guide 157
• Unmount and mount the source file system during the splitting of a Continuous Access XP Journal
pair volume.
• Connect the target file system to the NAS package.
• Unmount and delete the target file system before the Continuous Access XP Journal pair is
resynchronized.
• Notes on changing system configuration during Continuous Access XP Journal operations
When changing the following system configurations during Continuous Access XP Journal operations,
you must change the RAID Manager XP configuration definition files in CL1 and CL2 to which the
Continuous Access XP Journal P-VOL is connected, and in CL1 and CL2 where the S-VOL is used:
• Changing fixed IP addresses
• Expanding or deleting source file systems
• Setting up, expanding, or releasing differential-data storage devices for NAS Sync Image
When the host name is specified in the RAID Manager XP configuration definition file and you change
the following system configurations, you must change the configuration definition file:
• Editing the
/etc/hosts
file (when resolving the host name using the
/etc/hosts
file)
• Changing registration information on NIS servers, or changing settings for NIS servers (when
resolving the host name using NIS)
• Changing registration information on DNS servers, or changing settings for DNS servers (when
resolving the host name using DNS)
• Notes on using external volumes
For periodic maintenance of external LUs, you must delete all Continuous Access XP Journal pairs once.
Preparing for Continuous Access XP Journal operations
Preparing for Continuous Access XP Journal volume pair operations
See ” Configuring primary and secondary arrays for Continuous Access XP Journal operations ” on
page 56 and prepare for creating Continuous Access XP Journal volume pairs. However, when
performing Continuous Access XP Journal pair operations (which are mentioned in step 8 and later in that
section), see ” Registration of public key used for SSH ” on page 157 and later sections and use RAID
Manager XP to perform the operations.
Registration of public key used for SSH
Before issuing the commands described in this document, the public key used for SSH must be registered in
the NAS package in which the Continuous Access XP Journal P-VOL is connected and also in the NAS
package that uses the S-VOL. For the registration of the public key, see the NAS Blade Manager User’s
Guide.
Configuring the RAID Manager XP environment
Log in to the target NAS package using SSH
Using the nasroot account via SSH, log in the NAS package in which the Continuous Access XP P-VOL is
connected and the NAS package that uses the S-VOL. (For information about login, see the appropriate
documentation for each tool in a platform.)
Configure RAID Manager XP configuration definition files
To control a Continuous Access XP Journal pair using RAID Manager XP, you must first define the
Continuous Access XP Journal pair using the RAID Manager XP configuration definition file.
Installing NAS Backup Restore creates templates of the RAID Manager XP configuration definition file in
which only the
HORCM_MON
section and the
HORCM_CMD
section are described.
• The template of the RAID Manager XP configuration definition file for instance number 16 is:
/home/nasroot/horcm16.conf
• The template of the RAID Manager XP configuration definition file for instance number 17 is:
/home/nasroot/horcm17.conf
