[PATCH 1/2] Do not run discovery on portals that open-iscsi is logged-in to
Running a discovery on a portal that open-iscsi is logged in to may result
in changes to a logged-in node (like changing the node's transport type).
Changing these properties shouldn't be done while logged in.

Re: Open iscsi causes machine to hang on reboot
I see that you were able to resolve this problem. I had a similar problem so I'll state the resolution here for posterity. My problem was that the shutdown scripts didn't seem to be ordered properly. The network was getting shut down before iscsi had a chance to clear the cache, so the iscsi daemon was hanging. I reordered the scripts and it started working. I know this isn't recommended, but it worked for me.

Do not use the tools or iscsi modules from Ubuntu. I am happy to report that after a download, make and make install the machine is now able to reboot properly. :) Regards, -- Andreas Bergstrøm Østfold University College Dept. of Computer Scienceshttp://media.hiof.no/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

Re: setting up initiator-target pair
__mango wrote: I am trying to set up an iscsi communication. I use open- iscsi-2.0-865.15 for initiator and iscsitarget-0.4.0 as target. 1. Is this target compatible with the initiator. It should be. I think that many people use that target (although I don't). 2. There is no issue with kernel versions. i try to set up a session and i get absolutely no messages. It tells initiator is running fine. First, make sure that your initiator name was set correctly in /etc/iscsi/initiatorname.iscsi What's the output of the following commands: 1. open-iscsi service: 1. If you're running on RedHat: /etc/init.d/iscsi status 2. If you're running on SuSE: /etc/init.d/open-iscsi status 2. iscsiadm -m node 3. iscsiadm -m session If iscsiadm -m node doesn't show any nodes, you'll need to discover them first. Try the iscsi_discovery script. It also has a man page. If iscsiadm -m node shows nodes but iscsiadm -m session doesn't show any nodes, try to login to those nodes. I think that the README has some very useful examples. 3. The ReadMe s are not of much help. Can anyone redirect me to a place where there is a doc about practical setup of an iscsi. I don't know about other docs. BTW - did you read the man pages? Erez --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.
