Apr 21 12.2 GI PSU fails with "OPATCHAUTO-72141: Grid is installed only on a single node"

I have recently faced this issue.

While patching my newly built 12.2 RAC in rolling mode using opatchauto, it fails with following error.

After quite a bit of research, found it to be a bug.

Bug 26367944 - LNX-12201.170718GIRU:OPATCH SHOULD VALIDATE NONROLLING ON ONE HUB NODE CLUSTER 

Oracle Note Id :

Opatchauto fails with OPATCHAUTO-72141: Grid patching cannot be performed in rolling mode on single node cluster (Doc ID 2336186.1)

Solution

I ran it like the following.

[root@OEL7N1 grid]# opatchauto apply /dboracle/PSU/32540149 -oh /u01/app/oracle/12.2.0/grid -nonrolling

It ran fine.
