Fix PowerHA/HACMP cluster version & node name mismatch

Step-by-step procedure to fix PowerHA/HACMP version mismatch and node name mismatch by correcting ODM entries:

Fix PowerHA/HACMP Version & Node Name Mismatch via ODM Editing:

Backup current ODM directories:
# tar -cvf hacmp.odm.tar /usr/es/sbin/cluster/etc/objrepos
# tar -cvf system.odm.tar /etc/objrepos
Always keep a backup before making ODM changes.

Fix HACMP cluster version issue ODM object

Export the HACMPcluster object to a file:
# odmget HACMPcluster > cluster.file
Edit cluster.file and correct the cluster_version field to the desired version:
# vi cluster.file
Delete the current HACMPcluster ODM entries:
# odmdelete -o HACMPcluster
Re-add the corrected cluster configuration:
# odmadd cluster.file
Verify the changes:
# odmget HACMPcluster

Rebuild and start cluster config manager:

/var/hacmp/clverify/clmgr -s

clmgr start cluster

Monitor cluster manager logs:

tail -f /var/hacmp/log/clstrmgr.out

Look for errors or confirmation of cluster manager starting successfully.

Fix HACMP Node ODM object

Backup current ODM directories:
# tar -cvf hacmp.odm.tar /usr/es/sbin/cluster/etc/objrepos
# tar -cvf system.odm.tar /etc/objrepos
Always keep a backup before making ODM changes.

Export the HACMPnode object to a file:
# odmget HACMPnode > nodes.file
Edit nodes.file and correct the version fields or node names as required:
# vi nodes.file
Delete the current HACMP Node ODM entries:
# odmdelete -o HACMPnode
Re-add the corrected node configuration:
# odmadd nodes.file
Verify the changes:
# odmget HACMPnode

Rebuild and start cluster config manager:

# /var/hacmp/clverify/clmgr -s

# clmgr start cluster

Monitor cluster manager logs:

# tail -f /var/hacmp/log/clstrmgr.out

Look for errors or confirmation of cluster manager starting successfully.

Summary:

• Back up ODM repos first.
• Export, edit, delete, and re-import the cluster and node ODM objects to fix version and node name mismatches.
• Verify after each step.
• Start the cluster service
