So I finally got my multipath running through both the NIC and HBA interfaces, but I'm not having any luck going through testing to verify it's actually failing over between the connections. # multipath -l mpath0 (30690a018f015191a6472441d1500f057) [size=4 GB][features="0"][hwhandler="0"] \_ round-robin 0 [active] \_ 3:0:0:0 sdc 8:32 [active][ready] \_ round-robin 0 [enabled] \_ 1:0:1:0 sdb 8:16 [active][ready] I can unplug the HBA (see below) and the connection to the SAN remains. # multipath -l mpath0 (30690a018f015191a6472441d1500f057) [size=4 GB][features="0"][hwhandler="0"] \_ round-robin 0 [active] \_ 3:0:0:0 sdc 8:32 [active][ready] \_ round-robin 0 [enabled] \_ 1:0:1:0 sdb 8:16 [failed][faulty] But when I unplug the NIC connection, the multipath command hands, trying to list files on the SAN partition hangs, and I'm getting these messages: Nov 19 17:15:13 ems1 kernel: iscsi-sfnet:host3: Connect failed with rc -113: No route to host Nov 19 17:15:13 ems1 kernel: iscsi-sfnet:host3: establish_session failed. Could not connect to target Nov 19 17:15:13 ems1 kernel: iscsi-sfnet:host3: Waiting 10 seconds before next login attempt How to troubleshoot this situation?
