3.6 Component monitoring examples

This section describes monitoring examples.
3.6.1 xCAT for power management, hardware discovery, and connectivity
If the expected state for a specific group is all nodes online and in a running state,
Example 3-68 shows the following issues:
The hostname is missing in /etc/hosts.
Three LPARs are inactive (the operating system is not running).
One LPAR is running but is not pinged.
Example 3-68 Three nodestat output problems
# nodestat lpar -p
