4.1.3 Node does not respond to queries or rpower command

If a node does not respond to queries from the xCAT commands (for example, rpower),
complete the following steps to check the service network status and the hardware
connection between XCAT and the hardware:
1. Check the syslog at /var/log/messages on the management node.
By default, the syslog is written into the /var/log/messages file. If the syslog PostScript
runs correctly for the node, the syslog message of the node is redirected to the
management node.
2. Verify the hardware connections between xCAT, the FSPs (CECs), and the BPAs (frames).
The /var/opt/isnm/hdwr_svr/data/HmcNetConfig file must contain two hardware connection
types for each BPA and each FSP. xCAT uses a connection type (-tooltype) of lpar and CNM
uses a connection type of CNM.
The lshwconn command is used to list and show the status of the hardware connections that
are defined in /var/opt/isnm/hdwr_svr/data/HmcNetConfig. Example 4-4 on page 247 and
