The disks are in the same state they would be in if you pulled the power plug. They may come up just fine, or they may be in a corrupt state. If you take snapshots frequently enough, you should have at least one good snapshot. Your other option is scripting. You can build custom scripts to leverage the VSS providers in Windows... but it won't be easy. Any reason in particular you're using iSCSI? I've found NFS to be much more simple to manage, and performance to be equivalent if not better (in large clusters). -- --Tim
