RE: [dm-devel] [ANNOUNCE] multipath-tools-0.4.1

["Caushik, Ramesh" <ramesh caushik intel com>]

The newer Qlogic (qla2xxx) driver for kernel versions 2.6.9 and later do not support the fc_transport class. The support is #ifdefed for kernels > 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 multipath tools. Thanks for feedback. 

Ramesh.

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

The attributes underneath remain the same. I believe this change occurred in the first rc1 patch to 2.6.9.
