Hello, In my research about stmfadm/itadm I have encountered an issue that I would like to discuss. We have multiple VLANs in which iscsi storage is delivered. If a host contacts comstar via sendtargets, it will receive a listing of all targets and including those with portal group ip addresses that the client cannot reach. Example client like open-iscsi will then attempt to connect to all target received and hang on a target for which the client cannot reach - it will hang and timeout after a while (sometimes a long while and this becomes painful when rebooting a host).
What I would like is that if an initiator is a member of a host group and the host group is associated with a view which has an association with a target group, then the initator should only see those targets that are in the associated target group. Of course this logic has to be evaluated for each view that the initiator is a member of a host group and then the union of resulting targets needs to be exposed. I understand that isns can resolve this issue, however with older iscsi clients that is not option and honestly introduces another layer of complexity. I understand the theory behind comstar that there is no 1:1 relationship lun and target. There have been some discussion about this issue - I am trying to see what people have thought about.
