Opatchauto Session failed: Parameter validation failed

While applying PSU on Grid Home in 12c, due to the patch conflict, you might have to rollback few patches before you could apply the PSU.

After rolling back the patches from grid home, when you try to run the opatch analyze command again, you might encounter following error:

[root ~]# $Grid_Home/OPatch/opatchauto apply /stage/PSUpatch/22191349 -analyze -ocmrf /stage/ocm.rsp

opatchauto failed with error code 1.

Then if you try to start the has services, you get following error:

 [root ~]# $Grid_Home/bin/crsctl start has

CRS-6706: Oracle Clusterware Release patch level ('3749979535') does not match Software patch level ('2278979115'). Oracle Clusterware cannot be started.

CRS-4000: Command Start failed, or completed with errors.

SOLUTION:

So in order to resolve this, you need to issue following command as root user:

$ORA_GI_HOME/crs/install/roothas.pl –postpatch

It will start the has services too.

Then again run the analyze command as given above and it will work.
