sorry but I am not sure what you mean.
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=20 GB][features="0"][hwhandler="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
different paths.
when sda failed multipathd identified the problem and diverted traffic
to sdb
but after correcting the sda problem, multipathd did not become aware of
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
them when they become valid.
but for some reason it does not.
