The newer Qlogic (qla2xxx) driver for kernel versions 2.6.9 and later d=
o not support the fc_transport class. The support is #ifdefed for kerne=
ls > 2.6.6 & < 2.6.9. So I will have to wait till they support this for=
 newer kernels. Meanwhile I can work with a patched version of multipat=
h tools. Thanks for feedback.=20

James, thank you for the clarification (and I didn't mean to string
anyone :).

Ramesh, I don't feel like going through the hassle of supporting
multiple synthax until the multipath target has made its way into the
standard kernel, so I'll keep guessing the node_name in
behing /sys/class/fc_transport/target<host>:<channel>:<target> or skip
the node_name fetch.

ok with you ?

regards,
cvaroqui
