PRIMECLUSTER Installation and Administration Guide 4.1 (for Linux)

C.1 Collecting Troubleshooting Information

If an error occurs in the PRIMECLUSTER system, collect the information required for the error investigation from all nodes that construct the cluster and the cluster management servers. Then, contact your customer support representative.

1. PRIMECLUSTER investigation information
   • Use pclsnap to collect information.
   • Retrieve the system dump.
   • Collect the Java Console on the clients.

     See "Appendix B.2.2 Java console" in the "PRIMECLUSTER Web-Based Admin View Operation Guide."

   • Collect a hard copy of the client screens.

     See "Appendix B.2.3 Screen hard copy" in the "PRIMECLUSTER Web-Based Admin View Operation Guide."

2. Investigation information for the failed application
3. Crash Dump

   If the failed node is restartable, manually collect a crash dump before restarting it. Crash dump will be useful for troubleshooting if the failure is OS related.

   Example) If the failover occurred due to an unexpected resource failure

   After the failover of the cluster application is complete, collect a crash dump on the node where the resource failure occurred.

   For details on the crash dump, see "Crash Dump."

4. Error reproduction procedure description if the error can be reproduced

• When reporting a problem, collect the information required for an error investigation. If you do not provide information for problem checking and error reproduction execution, it may take a long time to reproduce and diagnose the problem or it may become impossible to do so.
• Collect investigation material promptly from all nodes of the PRIMECLUSTER system. Necessary information may become lost if a long time elapses after the error occurs. This applies especially to information collected by pclsnap.
