Is it supported to remove default Oracle resource in Grid Infrastructure?

Questions and Answers

Grid Infrastructure will create a list of default resources once it's setup, some resources will have OFFLINE for both target and state if the feature is not being used.

For example, if ASM is not selected as storage option during GI installation(opposite of recommendation), ASM related resources will be created but remain in OFFLINE state. Also, if 9i database does not exist, ora.gsd resource will have OFFLINE state:

/bin/crsctl stat res -t
--------------------------------------------------------------------------------
NAME           TARGET STATE        SERVER                   STATE_DETAILS

It's NOT SUPPORTED to remove those OFFLINE resource even though they are not being used - upgrade or patching may expect these resources to be there and fail if they don't.
