It looks like the nop code it broken. If you use node.conn[0].timeo.noop_out_interval = 0 node.conn[0].timeo.noop_out_timeout = 0 Set that for each portal or set it in your /etc/iscsi/iscsi.conf file and then redo discovery. > May 5 21:15:05 manjula klogd: connection1:0: detected conn error > (1011) > May 5 21:15:05 manjula iscsid: Kernel reported iSCSI connection 1:0 > error (1011) state (3) > May 5 21:15:09 manjula iscsid: connection1:0 is operational after > recovery (1 attempts) > > The target is the infamous Promise m500i and the initiator "transport > class version 2.0-869. iscsid version 2.0-868" > Nic : Broadcom NetXtreme BCM5721 Gigabit Ethernet PCI Express (tg3) > Kernel 2.6.25-rc9-17-default x86_64 > > There is really no load on this system yet.

Normally if you do discovery to one port it will tell you about all of them on the target. The multiple sd entries is also expected. The scsi layer does not know or care if it can see the same LU from different paths, so it creates a sd everytime it sees it.
