A terminal window displays the status of HP Insight CMU extracting the golden image from
the golden node and preparing the image for diskless bootup.
To create the same oneSIS diskless logical group using the HP Insight CMU command line:
# /opt/cmu/bin/cmu_add_logical_group –n <logical group name> -d diskless-oneSIS –k <kernel version> -I <golden
node>
The -k option parameter must be the kernel version of the kernel that exists on the golden node
and the one you want to boot diskless (for example, the output of uname –r on the golden node).
