HACMP Installation and Cluster Definition 

For cascading resource groups the failed node is going to reaquire its 
resources, once it is up and running again. So, you have to restart HACMP on 
it through 

smitty clstart

 and check again for the logfile, as well as the 

clusters status.

Further and more intensive debugging issues are covered in Chapter 7, 
“Cluster Troubleshooting” on page 143.

Now that the actual installation is finished, the cluster is well documented in 
the planning sheets, all information from there has been implemented in the 
HACMP ODM, and the cluster is verified and synchronized; provided the 
initial testing didn’t bring up any curiosities, you should save this working 
configuration in a cluster snapshot.

The cluster snapshot utility allows you to save, in a file, a record of all the 
data that defines a particular cluster configuration. This facility gives you the 
ability to recreate a particular cluster configuration, a process called applying 
a snapshot, provided the cluster is configured with the requisite hardware and 
software to support the configuration.

You can perform many of the cluster snapshot utility operations, such as 
saving a configuration and applying a saved configuration, using the HACMP 
for AIX VSM application (

xhacmpm

). For more information, see the 

administrative facilities chapter in the 

HACMP for AIX, Version 4.3: Concepts 

and Facilities, SC23-4276, and the online help information available with the 
application.

In addition, a snapshot can provide useful information for troubleshooting 
cluster problems. Because the snapshots are simple ASCII files that can be 
sent via e-mail, they can make remote problem determination easier. 

You can also add your own custom snapshot methods to store additional 
user-specified cluster and system information in your snapshots. The output 
from these user-defined custom methods is reported along with the 
conventional snapshot information.

You cannot use the cluster snapshot facility in a cluster with nodes 
concurrently running different versions of HACMP for AIX.
