Hello group I am running a number of HP blade servers in a C7200 enclosure. Several of them have access to individual LUN's on an MSA 2012i using open-iscsi. Recently, however, I have experienced unexplained hangs of the servers in question and the only appearent thing they have in common (beside being blade servers) is that they have access to the IP- SAN.
When the servers fail, they do so in a fashion where they will still respond to, for example, ping requests. But they refuse to respond to higher level access, such as spawning a shell for login. This means that when the error occurs, I cannot even log into the machines to troubleshoot the problem (regardless of remote or local login), even though the console greeting is printed readily. My question is primarily whether this sounds like something the iscsi- driver could cause and, equally importantly, how one would go about troubleshooting the issue. One thing that makes it particularly elusive is that I cannot seem to provoke the error state and it does not occur very often (at least not while the platform is not yet in full production). Possibly relevant information follows: OS: centos-release-5-3.el5.centos.1 iscsi version: iscsid version 2.0-868 MSA: Current Storage Controller Code Version J210P12 I can, and have started, upgrades to more recent versions of all three. However, those were the versions running when the problem was caused last -- and since I cannot provoke it, I have no real way of knowing if version upgrades will solve the issue (unless someone in this group can confirm that it will, of course). Thank you for any advice you could offer. -- Niels --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
