HACMP - PowerHA Version mismatch after the migration

Note: Please check the following link before start the HACMP migration to know the PowerHA for AIX Version Compatibility Matrix,



http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/TD101347


Some times HACMP version will show the incorrect version after the upgrade from HACMP 5.3 to HACMP 6.1 then looking at the HACMPnode ODM entries on node1 and node2 we can see the mismatches with the version numbers.


To correct these we need to edit the ODM entries using the following instructions..


BEGIN ODM FIX


1. tar the ODM directory and save it off for safe keeping

# tar -cvf hacmp.odm.tar /usr/es/sbin/cluster/etc/objrepos

# tar -cvf system.odm.tar /etc/objrepos



2. fix HACMPcluster

#odmget HACMPcluster > cluster.file

 vi cluster.file and correct the cluster_version field

HACMP 5.5 is version 10

HACMP 6.1 is version 11 <<< Version 11

HACMP 7.1 is version 12


#odmdelete -o HACMPcluster (which removes the contents of the objectClass)

#odmadd cluster.file

#odmget HACMPcluster (to verify the correct cluster_version)



3. fix HACMPnode

#odmget HACMPnode > nodes.file

vi nodes.file and correct the version fields

#odmdelete -o HACMPnode (which removes the contents of the object class)

#odmadd nodes.file

#odmget HACMPnode (to verify the correct node version)


END ODM FIX

Then try starting HACMP services on problem node.
