iscsiadm uses the kernel interface for rescanning which does not remove devices. It only adds them as you saw. I am changing the component to reflect that we need to modify the kernel. We can shoot for RHEL 5.4. I am not sure if I will be able to complete it at this time though. Closer to RHEL 5.4 time I will know for sure. If you guys have the resources you can add it upstream and I can port it for you. That would speed things up. Updating PM score. Conditional NAK: UPSTREAM I do not think I have time for this because of offload and fcoe, but we might be able to get it done. If we get it upstream then the port should not be too hard. The more difficult issue may be to backport refcounting and state machine fixes that would probably be needed since we will probably be remove devices that are accessed by someone and so the scsi device refcuont would be greater than 0. Mike, I've started working on this patch. One question : Will we have rescan-scsi-bus.sh script included in RHEL5.4 sg3 utils package? (In reply to comment #4) > One question : Will we have rescan-scsi-bus.sh script included in RHEL5.4 sg3 > utils package? I am adding Rob Evers who is working on that. I guess if we are adding it, then we could just use that for rescanning. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Looking back at the comments, who has the ball here? I think we could probably just kill this for RHEL 5. For RHEL 5, maybe we should just have users us the rescan bus script. What do others think? NetApp - what do you think re: Comment #9? Andrius, I second your opinion. In fact We are asking customers to use rescan bus script to do addition/deletion of lun on RHEL5.4 host. Closing based on comments. |
