If you have multiple targets or if the target has multiple portals or if the target does a target for each lun (so you get multiple targets for each lun), then the initiator will setup each target, portal and lun in parallel. This results in the /dev/sdX naming not being persistent between reboots.

Do you see multiple targets or portals? If so then we are going to set them up in parallel and the /dev/sd names could be differnt for each reboot. After the iscsi service has started, you can run iscsiadm -m session -P 3 to see all the running sessions and what /dev/sdXs we got and what portal they are being accessed from (you should use the /dev/disk/ naming for something like fstab though). And you probably see multple /dev/sdXs because each path gets one. So if you have one lun and the target has two ports you would get two /dev/sdX entries. One for each path. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
