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 primary LANIP address.
ftsys9>netstat -in
