Jenifer, Thanks for uploading the file.
That's a cool, relatively large topology -- if I got it right, you've got 3x 2-port FC adapters (thus 6 FC SCSI hosts) connected via switch/fabric to a 2-port storage (thus 12 paths per LUN.) The good news is multipath has visibility of all 12 paths per LUN, so not a path detection/discovery issue. Interestingly, it also has displays the current multipath devmaps table and status (from device mapper), and that *does* show 12 paths, in Active status, in 2 priority groups as expected (ALUA storage.) Therefore, as the multipath devmaps appear to be configured correctly, this suggests the issue seems be on path listing (multipath -ll). (The evidence that missing paths also happen on the direct-attached system, w/ 4 paths per LUN, possibly supports that, in the sense that this is not related to the attachment type, ie, fabric/direct.) Could you please attach the output of these commands? # multipath -ll -v3 > multipath-ll-v3.log 2>&1 # dmsetup table > dmsetup-table.log 2>&1 # dmsetup status > dmsetup-status.log 2>&1 Thanks, Mauricio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860587 Title: multipath -ll doesn't discover down all paths on Emulex hosts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1860587/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
