ModeratorHello Rob,
There are two different points being brought up here that I will address individually. When running the command coro_config on a CDB that is on Oracle Linux 8, the option Enable Cluster Maintenance places the entire cluster in maintenance mode, meaning you only have to run this on one of the nodes and it will place the entire cluster into maintenance. If the CDBs are still on Oracle Linux 7, then you would have to run this on each node you want placed in maintenance.
As for doing this before running a VMware snapshot before an upgrade, we do not support running VMware snapshots on any SL1 appliance. The only supported backup process is the Config and Full Backups built into SL1. It is also unnecessary to place the cluster into maintenance before an upgrade.
