Review the troubleshooting options, known problems, and their solutions.
Running Script for Engineering Support Analysis
You can use a script to gather information about the configuration and status of your cluster and
its various modules. The script will also identify package information, debugging messages,
console messages, and information about disk groups and volumes. You can forward the output
of this script to HP customer support who can analyze the information and assist you in solving
any problems. Table A-1 lists the script you can use to gather the required information.
Table A-1 Scripts for Engineering Support Analysis
DescriptionScript
This script gathers information about the GAB and LLT modules. The file /tmp/
commslog.time_stamp.tar contains the script’s output.
On each node, enter:
# /opt/VRTSgab/getcomms -local
getcomms
Troubleshooting Tips
Review the information on the error logs that you must access.
• To check the Oracle installation error log, you must access:
$ORACLE_BASE/oraInventory/logs/installActionsdate_time.log
This file contains errors that occurred during installation. It clarifies the nature of the error
and at exactly which point it occurred during the installation. If there are any installation
problems, you must send this file to Tech Support for debugging the issue.
Troubleshooting Oracle
For help resolving issues with Oracle components, check the following information:
• Oracle log files
• Oracle notes
Oracle Log Files
Review the information on the files that you must access.
• To check the Oracle log file
— For Oracle 10g R1: $ORA_CRS_HOME/crs/log
— For Oracle 10g R2: $ORA_CRS_HOME/log/<hostname>/crsd/
