Re: [Users] iscsi discovery issue
Hi Dafna, I just started working on this again, and it now did pick up the change - so my assumption for now is that it must have been locally cached on the Hyper-Visor... I'll do some more testing to re-create this and if it happens again, i'll email you the logs.

Re: [Users] iscsi discovery issue
Hi Alex, theoretically, even if the target is already logged in, engine is sending a query called getDeviceList which should update the information that was changed for the target. can you please attach the logs (both engine and vdsm)? also, if you can give me more information on what storage are you using and what exact commands (or steps) you did it would be most appreciated.
