I am using an iscsi initiator (linux-iscsi rev 4.2) and this is what the multipathd daemon sees pepper:~ # multipath -l dm names N dm table 3600c0ff00000000007c1d167985b4b06 N dm table 3600c0ff00000000007c1d167985b4b06 N dm status 3600c0ff00000000007c1d167985b4b06 N dm info 3600c0ff00000000007c1d167985b4b06 O 3600c0ff00000000007c1d167985b4b06 [size=3D20 GB][features=3D"0"][hwhandler=3D"0"] \_ round-robin 0 [enabled] \_ 14:0:0:0 sda 8:0 [failed] \_ round-robin 0 [active] \_ 14:1:0:0 sdb 8:16 [active] sda and sdb are actually the same device discovered by iscsi via 2=20 different paths. when sda failed multipathd identified the problem and diverted traffic=20 to sdb but after correcting the sda problem, multipathd did not become aware of=20 this and of course when i failed sdb it did not failback to sda. i know that multipathd is suppose to poll for failed paths and reinstate=20 them when they become valid. but for some reason it does not.
