Troubleshooting Approaches
The following sections offer a few suggestions for troubleshooting by
reviewing the state of the running system and by examining cluster
status data, log files, and configuration files. Topics include:
• Reviewing Package IP Addresses
• Reviewing the System Log File
• Reviewing Configuration Files
• Reviewing the Package Control Script
•Using cmquerycl and cmcheckconf
•Using cmscancl and cmviewcl
• Reviewing the LAN Configuration
NOTE The use of Serviceguard Manager is recommended for observing the
current status of a cluster and viewing the properties of cluster objects.
See “Using Serviceguard Manager” in Chapter 7 for information about
running Serviceguard Manager.
Reviewing Package IP Addresses
The netstat -in command can be used to examine the LAN
configuration. The command, if executed on ftsys9 after the halting of
node ftsys10, shows that the package IP addresses are assigned to lan0
on ftsys9 along with the heartbeat IP address.
