iSCSI Discovery cannot detetect LUN
Hello all, please do you have some experience with troubleshooting adding of iSCSI domain to ovirt 4.1.1? I am chalenging this issue now: 1) I have successfuly installed oVirt 4.1.1 environment with self-hosted engine, 3 nodes and 3 storages (iSCSI Master domain, iSCSI for hosted engine and NFS ISO domain). Everything is working now. 2) But, when I want to add new iSCSI domain, I can discover it, I can login, but I cant see any LUN on that storage. (I had same problem in oVirt 4.1.0, so I made upgrade to 4.1.1) 3) Then I tryed to add this storage to another oVirt environment (oVirt 3.6) and there are no problem. I can see LUN on that storage and I can connect it to oVirt. I tryed to examine vdsm.log, but it is very detailed and unredable for me :-/ Thak you in advance, have a nice day, -- Lukas Kaplan

Are you sure mappings are correct? Can you ensure the LUN is empty? Y.
3) Then I tryed to add this storage to another oVirt environment (oVirt 3.6) and there are no problem. I can see LUN on that storage and I can connect it to oVirt.
