When I was doing some testing of service failover I ran into something that I think is interesting behaviour. If I issue an “abort” command I expect an abort, not a bit of tidying up before aborting, which is what I found the following command doing:
srvctl shutdown instance -d <database name> -i <instance name> -o abort

This probably isn’t going to change anyone’s life, but no harm in knowing it 🙂
