When you log-in the session is also cached. So you init script should take advantage of that and automaticly log-in to those targets. You did log-in to those targets after the discovery, right? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

I will try again to see if they are cached (centos 5.1) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

Can anyone tell me where this is, I cannot find it any more. If you have a target with LUN1 and one portal, and if you have hostA and hostB running open-iscsi. HostA will create one connection to the target and through that we will access LUN1 and any other logical units on the target. If the target only has one portal then we will only create one connection to the target for hostA (open-iscsi creates one connection per portal on the target basically). For hostB, the initiator running on that will create another connection to the target. My second question is about startup. At the moment I start iscsi, then I run the discovery command, then restart iscsi to see the disk. After discovery you can just run iscsiadm -m node -T target -p ip:port -l to login into a specific portal that was found. There are lots of variations on this.
