How to rollback a patch using patchmgr in EXADATA


  
Can we rollback a patch applied using the utility patchmgr?

Yes we can, however only those patches can be rolled back which has successfully patched the EXADATA cells. 

Cells with incomplete/Failed patching cant be rolled back.

How to do:

1. Check the prerequisites using the below command:

./patchmgr -cells cell_group -rollback_check_prereq [-rolling]

2. Perform the rollback using the following command:

./patchmgr -cells cell_group -rollback [-rolling]
