7. Select one of these kernels, and then click OK. The diskless image building process launches.
This operation might last several minutes while files copy from all file systems of the golden
node to build the diskless image.
From the CLI
1. Start the HP Insight CMU CLI:
# /opt/cmu/cmucli
2. To create the diskless group, you must know the IP address and the kernel name of the golden
node used by the diskless nodes. To get the kernel name, use the probe_kernel command:
cmu> probe_kernel 16.16.185.192
2.6.9-42.EL
2.6.9-42.ELsmp
kabi-4.0-0
kabi-4.0-0smp
cmu> add_logical_group <myTestImage> 16.16.185.192 "2.6.9-42.ELsmp"
4.8.9 Adding nodes into the logical group
From the GUI
1. Select nodes to add to the diskless image logical group.
2. Click Add.
This creates the read/write directory for each node and the corresponding diskless image.
The more nodes you add, the longer this operation takes.
