40 | Enabling and Configuring Data Replication
At a glance, here is an overview of the steps to enable, configure, and use replicate jobs:
1. Configure data partitions on the remote (target) servers.
2. Enable Data Replication licensing using the VTS web interface as described in Enabling
Licensed Features on page 15.
3. Configure source and target settings using the web interface.
4. Replicate data to remote servers by creating and running replicate jobs.
To recover data from a target server, you can restore virtual tapes using the Manage External
Data page of the web interface. You can then select the target server and list of virtual tapes
to restore. Refer to the help for more information.
Configure data partitions on target servers
To dedicate data partitions on a target server for use in replication, you can
• rename existing vault partitions, or
• add additional storage partitions to your server
To rename existing vault space
1. Remove or erase virtual tapes and pools in the file system chosen to be used as a data
partition. (Data currently residing in the vault partition will no longer be accessible to
host systems.)
2. Rename an existing partition. Note that you must move (rename) the vault mount point to
the new data mount point. Data file systems must be labeled DATAxx, where xx is a two-
digit number following the name. The file systems do not need to be numbered
sequentially.
a. Unmount the file system:
umount /VAULT04
b. Copy the /etc/fstab file to a backup file:
cp /etc/fstab /etc/fstab.backup
c. Relabel the device, using the file system name:
e2label /dev/sdc2 /DATA04
d. Edit /etc/fstab and replace the old “VAULTnn” name with the new “DATAnn” name.
e. Rename the mount point:
mv /VAULT04 /DATA04
f. Mount the file system and set permissions:
mount /DATA04
chown bill.root /DATA04
chown bill.replicators /DATA04
chmod 750 /DATA04
3. Repeat these steps for each partition you wish to rename.
To add data partitions on existing external storage devices
Complete the steps from Adding vaults on external storage devices on page 11 with the
following caveats:
