HP Insight Cluster Management Utility v7.1 User Guide

• Some details about output processing results, which are provided on the right.
Characters that differ from the reference node are highlighted in red. In this example, the time drift
in the “seconds” field differs.
Depending on the output length, the output of cmudiff can be piped to the less editor to enable
scrolling through the output with arrows. Output editing is terminated by entering q.
Example 2 dmidecode command
This example uses cmudiff to detect BIOS firmware differences with the dmidecode command.
cmu_pdsh> dmidecode
NOTE: The window shows only 2% of the output. Use the arrows to scroll up and down.
A difference is found in the BIOS release date. The comment “2 populations, not displayed” on
the right suggests that two groups of nodes are present with two different BIOS release dates. One
of the two populations might be a single node without a firmware upgrade.
Display the full list of cmudiff options:
cmu_pdsh> cmudiff –h
Narrow the search of the failing nodes with the -d option to display node populations:
cmu_pdsh> cmudiff –d
