4 Provisioning a cluster with HP Insight CMU

4.1 Logical group management

A logical group in HP Insight CMU represents a disk image that has been captured (backed up).

Each logical group is associated with a single backup image. The logical group must contain the nodes with good hardware configurations that can be cloned with this image.

The Logical Group Management window is used to add, modify, delete, or rename logical groups.

After the HP Insight CMU rpm is initially installed, only the default logical group exists. You cannot perform backup operations in the default logical group. A new logical group must be created.

In the Logical Group Management window:

1.Click Cluster Administration→Logical Group Management→Create a Logical Group Figure 14 Create a logical group

2.The following window appears. Figure 15 Add logical group

3.Enter the group name. In the associated devices field, enter the disk type of the node to be backed up:

• For the first SCSI drive, use sda.
