ODA - Update to 12.2.1.4 - issue with ora.net1.network

Yesterday, I had to update an ODA from Release 12.1.2.12 to 12.2.1.4 . All prerequisite checks including prepatchreport were successful ... but the update itself not!

During the update, at stage 'GI Home Cloning', the update process failed and left the system in an 'unknown' state. A detailled analysis has shown the root cause: crs service qosmserver is missing. So, I tried to setup this missing link to a successful update:

srvctl add qosmserver
srvctl status qosmserver
srvctl start qosmserver

But, qosmserver could not be started - resource 'ora.net1.network' is missing. Well, that's absolutely true - we do not have such a resource defined for our ODAs. Finally changed the first of our vlan definitions to ora.net1.network and could start qosmserver.

Unfortunately and because of the interrupted update, GI is now using its 12.2 home, but odacli describe-component shows, that the current home is the old 12.1 - that finally results in a situation where I cannot run update-server again (GI Home Cloning fails, because the new GI Home already exists)

Outcome: As additional prerequisite, check, wether or not the resource ora.net1.network exists on Your ODA and be sure qosmserver is up and running BEFORE starting an 'odacli update-server'.
