Chapter 7. Cluster Troubleshooting
Typically, a functioning HACMP cluster requires minimal intervention. If a problem occurs, however, diagnostic and recovery skills are essential. Thus, troubleshooting requires that you identify the problem quickly and apply your understanding of the HACMP for AIX software to restore the cluster to full operation.
In general, troubleshooting an HACMP cluster involves:
•Becoming aware that a problem exists
•Determining the source of the problem
•Correcting the problem
Becoming aware of a problem is often through system messages on the console,
