How to stop and start the hacmp cluster in aix?


1. Ground work:

/usr/es/sbin/clu*/utiI/clRGinfo      --> To check the RG online status
lssrc -ls clstrmgrES                          --> To check the cluster manager is stable on both nodes
cat /var/hacmp/clverify/clverify.log  --> To check and confirm the log file has no errors.


Take a snapshot of the cluster

smitty hacmp
            extended configuration
                        snapshot configuration
                                    Create snapshot of the cluster configuration
                                                cluster snapshot name / Cluster snapshot description
