<div dir="ltr"><br>Hi! I would some help to restablish iscsi connections from a physical server to SAN storage (instance volume). <br><br>Scenario: I've 5 compute nodes, 1 controller, 1 network node and 1 storge with iscsi. I had some VMs running on compute node 1. I had a switch problem so the connection between the physical server (hypervisor) and the SAN storage was lost (I can see that on logs, multipath tried to change the path e after that it removed the /dev/mapper/<id>). <br><br>After restablish the switch I can't start the VM. What I'm seeing is that the hypervisor doens't have the device mapper path used in VM description (libvirt). <br><br>/dev/disk/by-id/dm-uuid-mpath-360050763008108e54800000000000039<br><br>From Horizon dashboard I can't detach the volume neither restart the VM. I can change the volume state from command line, reattach on VM but it doesn't start. The device can't be found. <br><br>So, how can I recreate the iscsi sessions on the physical server? I think if the device be recreated the VM can be started. <br><br>Is there some recomendation on using multipath? Can the multipath be configured to not remove the all the paths (from /dev) when a flaw occur?<br><br>Thank you!<b><br><br clear="all"></b><div><div class="gmail_signature"><div dir="ltr">- JLC</div></div></div>
