Centos5.6 FC multipathing errors to SUN6140

Posted on 2011-10-21

I've got a number of Centos/XEN servers connecting over fibre to my SUN Storagetek SAN with native multipath. The configuration seems to work fine and failover testing successful.

However, I'm getting errors on boot (see attached doc with screenshots)

The question is - should I be worried about this or is it normal?

Here's the multipath output also.

[root@hv03 ~]# multipath -ll
mpath2 (36001405bd0f13fcd5baed422edbfa4dd) dm-5 QNAP,iSCSI Storage [size=2.0T][features=0][hwhandler=0][rw]
\_ round-robin 0 [prio=1][active]
 \_ 15:0:0:0 sde 8:64  [active][ready]
mpath1 (3600a0b800029fa5200000e334e9f3e20) dm-2 SUN,CSM200_R

    Can you convert your screenshot to JPEG or PDF or something readable without involving M$?

    mpath2 seems to only have one path. Is that correct? You might try putting the multipath output in a code block to help with formatting.

    Accepted Solution

    It turns out that this is expected behaviour for an active passive configuration.
