When you say server side, do you mean server on the initiator box you deleted the target/portal record? If so, then the tools cannot probably not match objects properly. When you delete the target/portal record, you should have actually got a error saying you cannot delete it while logged in. If when you say server, you mean you deleted it on the target, then in non-discoveryd mode the logout should work fine. iscsiadm should not report any errors at least. If the target has already been detected as down, we just force a shutdown of the session. What this means is that since the session is dropped, we do not send a logout and instead just clean up the kernel/userspace structs and return. If we have not yet detected the target is down, then we would try to send a logout. That would timeout which would lead to us dropping the session, and then doing a forced shutdown like in the other case. -- You received this message because you are subscribed to the Google Groups open-iscsi group.

Errors when log out a deleted target
Hi experts, When I try to log out a target which is already deleted at the target server side, I can see a error : Logging out of session [sid: 1, target: iqn.2015-07.com.example:test:844a36e0-e921-4988-9538-a32112aa40d4, portal: 147.2.207.200,3260] iscsiadm: Could not logout of [sid: 1, target: iqn.2015-07.com.example:test:844a36e0-e921-4988-9538-a32112aa40d4, portal: 147.2.207.200,3260]. iscsiadm: initiator reported error (9 - internal error) iscsiadm: Could not logout of all requested sessions I think maybe the reason is that, the target is deleted, so the initiator can not get a logout response PDU, so errors.We would meet the same situation when target still alive but network down. I have a proposal, can we set a time out values, for example 10 seconds, once time out, log out anyway, then print some message like The target is not reachable, logged out. I think this operation is not harmful to the target side. Do you experts think that make sense?

Re: Errors when log out a deleted target
Hi experts, I have another concern, if we log out a deleted target, I think that is fine. But if we log out a network blocked target anyway when the log out PDU time out, will the target side keep the information of the initiator? Maybe that would introduce some confliction in next login.
