in DSS V7, it isn't possible anymore to change iSCSI options of a single Volume when the A-A-cluster is running - even if the volume isn't part of the cluster, not to mention if it has't a replication task assigned to.
As far as I remember, this was possible in DSS6.
Any idea, why this was changed from DSS6 to DSS V7? To me, there's no technical reason...
