Re: cluster group

All networks designated for cluster use on the node where the disk is online
would have to fail so a regroup could be initiated and another node in the
cluster could arbitrate for the resource and bring it online.

I'm a little confused as to why a group would contain a single disk resource
and nothing else. We used to do this with the quorum drive in NT 4. Now we
do it with the full expectation the lone disks will be either moved into
another group, or will be joined by other resources that can be used to
access the data that is stored on it (e.g. IP address, Network Name, File
Share Resource, Print Spooler, SQL, Exchange, etc...)
