Rolling Upgrade and Driver Installation Issues

During an upgrade, while running the Oracle Clusterware root.sh script, you may see the following messages:

• ACFS-9427 Failed to unload ADVM/ACFS drivers. A system restart is recommended.

• ACFS-9428 Failed to load ADVM/ACFS drivers. A system restart is recommended.

If you see these error messages during the upgrade of the initial (first) node, then do the following:

1. Complete the upgrade of all other nodes in the cluster.

2. Restart the initial node.

3. Run the root.sh script on initial node again.

4. Run the Oracle_home/cfgtoollogs/configToolAllCommands script as root to complete the upgrade.

For nodes other than the initial node (the node on which you started the installation):

1. Restart the node where the error occurs.

2. Run the orainstRoot.sh script as root on the node where the error occurs.

3. Change directory to the Grid home, and run the root.sh script on the node where the error occurs.
