If upgrade of Oracle Grid Infrastructure fails on remote nodes, then you can follow these steps to downgrade Oracle Grid Infrastructure to the earlier release.
Run this procedure from an already upgraded node where the Grid Infrastructure stack of the latest release is running, and downgrade each node where upgrade has failed or completed.
- Shut down the Oracle Grid Infrastructure stack on the remote node that is being downgraded:
- From the later release Grid home, run the command:
clscfg -nodedowngrade -h hostname
hostname is the host name of the remote node that is being downgraded.
- From the remote node that is being downgraded, run the command:
rootcrs.pl -downgrade -online
- Start Oracle Grid Infrastructure stack on the remote node from the earlier release Grid home:
- After all remote nodes are downgraded, downgrade the last remaining node using the procedure described in Downgrading Oracle Grid Infrastructure after Upgrade Fails.
Note:
You can downgrade the cluster nodes in any sequence.
