Thanks!
Now it looks different. Think I got what you meant. Or didn't I?
Mostly I changed the config file to contain a multipath section. See
below.
416L3 (360060160200161a037f90d75dfca84f7)
[size=20 GB][features="0"][hwhandler="0"]
\_ round-robin 0 [enabled]
\_ 6:0:1:1 sde 8:64 [faulty][active]
\_ round-robin 0 [enabled][first]
\_ 7:0:0:1 sdg 8:96 [ready ][active]

As you see above, I didn't manage that yet. Snip of the config that
produces the above:
multipaths {
multipath {
wwid 360060160200161a037f90d75dfca84f7
alias 416L3
path_grouping_policy failover
path_selector "round-robin 0"
features "0"
hardware_handler "1 emc"
}
}
Is that syntax correct? I don't get the activation of the second path.
Is it the release? Should I upgrade from 0.4.2.3? I'd pefer to keep the
debian package for simplicity and I didn't find anything sounding
important in ChangeLog.
Regards,
Philipp
