– All other objects with default names are renamed during the restore process. The new names appear
in the format name_r.
where name is the name of the object in your cluster.
The backup feature of the svcconfig CLI command is designed to back up information about your cluster
configuration, such as volumes, local Metro Mirror information, local Global Mirror information,
managed disk (MDisk) groups, and nodes. All other data that you have written to the volumes is not
backed up. Any application that uses the volumes on the cluster as storage, must back up its application
data using the appropriate backup methods.
You must regularly back up your cluster configuration data and your application data to avoid data loss.
If a cluster is lost after a severe failure occurs, both cluster configuration and application data is lost. You
must reinstate the cluster to the exact state it was in before the failure, and then recover the application
data.
Perform the following steps to back up your cluster configuration data:
1. Back up all of the application data that you have stored on your volumes using your preferred
backup method.
2. Open a command prompt.
3. Issue the following command to log on to the cluster:
ssh -l admin your_cluster_name -p 22
where your_cluster_name is the name of the cluster for which you want to back up cluster
configuration data.
4. Issue the following CLI command to remove all of the existing cluster configuration backup and
restore files that are located on your configuration node in the /tmp directory.
svcconfig clear -all
5. Issue the following CLI command to back up your cluster configuration:
svcconfig backup
The following output is an example of the messages that are displayed during the backup process:
CMMVC6112W io_grp io_grp1 has a default name
CMMVC6112W io_grp io_grp2 has a default name
CMMVC6112W mdisk mdisk14 ...
CMMVC6112W node node1 ...
CMMVC6112W node node2 ...

The svcconfig backup CLI command creates three files that provide information about the backup
process and cluster configuration. These files are created in the /tmp directory of the configuration
node.
The following table describes the three files that are created by the backup process:
File name
svc.config.backup.xml
svc.config.backup.sh
svc.config.backup.log
6. Issue the following command to exit the cluster:
exit
7. Issue the following command to copy the backup files to a location that is not in your cluster:
