Hi, I needed a little help or advice with my setup. I'm trying to configure multipathed iscsi on a CentOS 5.4 (RHEL 5.4 clone) box. Very short version: One server with two NICs for iSCSI sees storage on EMC. Storage shows up as four discs, but only one works. So far single connections work: If I setup the box to use one NIC, I get one connection and can use it just fine. When I setup multiple connections I have problems... I created two interfaces, and assigned each one to a NIC iscsiadm -m iface -I iface0 --op=new iscsiadm -m iface -I iface0 --op=update -n iface.net_ifacename -v eth2 iscsiadm -m iface -I iface1 --op=new iscsiadm -m iface -I iface1 --op=update -n iface.net_ifacename -v eth3 Each interface saw two paths to their storage, four total, so far so good. I logged all four of them them in with: iscsiadm -m node -T <long ugly string here> -l I could see I was connected to all four via iscsiadm-m session At this point, I thought I was set, I had four new devices /dev/sdb /dev/sdc /dev/sdd /dev/sde Ignoring multipath at this point for now, here's where the problem started. I have all four devices, but I can only communicate through one of them: /dev/sdc. As a quick test I tried to fdisk all four partitions, to see if I saw the same thing in each place, and only /dev/sdc works. Turning on multipath, I got a multipathed device consisting of sdb sdc sdd and sde, but sdb sdd and sde are failed with a message of checker msg is "emc_clariion_checker: Logical Unit is unbound or LUNZ" I'm in the dark here. Is this right? Obviously wrong? Thanks --Kyle -- You received this message because you are subscribed to the Google Groups "open-iscsi" group. To post to this group, send email to [email protected].
