HP Insight Cluster Management Utility manual # /opt/cmu/image/logicalgroupname

IMPORTANT: If partitions to be backed up are less than 50% empty, you must configure HP Insight CMU to use the tmpfs file system for cloning partitions. To make this functionality work, two conditions must be satisfied:

•The size of the largest partition to back up and clone must be smaller or equal to the compute node memory size.

•Cloning must be enabled using tmpfs by setting CMU_CLONING_USE_TMPFS to yes in

/opt/cmu/etc/cmuserver.conf and then restart HP Insight CMU.

If these conditions are not satisfied, subsequent cloning operations will fail.

A window displays the backup status.

Figure 21 Backup status window

While the backup is processing, you cannot use the compute node but you can perform other tasks with the HP Insight CMU GUI interface. When the backup is successfully executed, a message box appears.

After a successful backup, the /opt/cmu/image/logicalgroupname directory on the management node contains the image backup files. For example:

#/opt/cmu/image/logicalgroupname
