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 HP recommends you use Serviceguard Manager as a convenient way to
observe the status of a cluster and the properties of cluster objects: from
the System Management Homepage (SMH), select the cluster you need
to troubleshoot.
Reviewing Package IP Addresses
The netstat -in command can be used to examine the LAN
configuration. The command, if executed on ftsys9 after ftsys10 has
been halted, shows that the package IP addresses are assigned to lan0 on
ftsys9 along with the primary LANIP address.
ftsys9>netstat -in
