I have a rhel7 host with vdsm-4.14.13-1.el6ev installed. (not RHEV-H) Exposed a new LUN to the host by FC. When trying to create a new FC domain, issue_lip is executed for every attepmt, but for some reason, the new device appears only after a few attempts of scanning the SCSI bus Nir, I guess this is not the expected behaviour.

Can you reproduce this when vdsm is not running? 1. Expose new device 2. Run manually the issue_lip command If this is reproducible, we should open a kernel bug for this, and this bug should be blocked on the kernel bug. I've executed the scenario 10 more times, while vdsm is running and also manually when it's stopped, only I've waited a few seconds between the LUN mapping and scanning the SCSI devices. When vdsm is running, the new LUN gets visible every time to the host by multipath and can be used as a pv for FC storage domain. Moving the bug to VERIFIED. Used rhev3.4.2 vdsm-4.14.13-1.el7ev.x86_64 rhevm-3.4.2-0.1.el6ev.noarch |
