Hi,
Have noticed that one of our iscsi disks is showing as faulty:
imonitor01 (3600144f0e282490000004a81fc5d0005) dm-4 NEXENTA,COMSTAR
[size=1024G][features=0][hwhandler=0][rw]
\_ round-robin 0 [prio=0][enabled]
\_ 10:0:0:2 sdaa 65:160 [failed][faulty]
\_ round-robin 0 [prio=49][active]
\_ 11:0:0:2 sdal 66:80 [active][ready]
\_ round-robin 0 [prio=24][enabled]
\_ 8:0:0:2 sde 8:64 [active][ready]
\_ round-robin 0 [prio=11][enabled]
\_ 9:0:0:2 sdp 8:240 [active][ready]
though do not understand why as the same disk via alternative paths is okay.
If I check one of the other nodes, using a different disk, one the same
subsystem and network the paths are all okay:
ildap02 (3600144f0e2824900000049d1a3350001) dm-14 NEXENTA,COMSTAR
[size=1024G][features=0][hwhandler=0][rw]
\_ round-robin 0 [prio=24][enabled]
\_ 11:0:0:1 sdak 66:64 [active][ready]
\_ round-robin 0 [prio=49][enabled]
\_ 8:0:0:1 sdd 8:48 [active][ready]
\_ round-robin 0 [prio=11][enabled]
\_ 9:0:0:1 sdo 8:224 [active][ready]
\_ round-robin 0 [prio=99][active]
\_ 10:0:0:1 sdz 65:144 [active][ready]
Path 10 is showing absolutely fine. Everything is functioning okay but do keep
getting the following in messages:
Dec 8 07:32:14 kvm01 multipathd: sdaa: tur checker reports path is down
That is the only disk which is reporting an issue; and I have checked the
configuration multiple times now and cannot see anything wrong. I have
rescanned as-well and no errors have been produced.
Any ideas please ?
Does "iscsiadm -m session -P 3" show the session state as logged in?
If you do your own sg_turs /dev/sdaa what does it return? If it returns
error could you do
sg_turs -v /dev/sdaa
and send the output?
