What version of open-iscsi and what is the ping timeout? Could you try the kernel modules and tools from http://www.open-iscsi.org/bits/open-iscsi-2.0-871.tar.gz. I did a tiny change to the ping code, and it looks like for some other group it has fixed their problem (at least I have not heard back from them in a couple of weeks). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
