[Lustre-discuss] lustre and multi path

[Stuart Marshall]

Hi Brock,

We have sun oss's mds's and fc attached arrays all connected via an fc
switch.  We use sun's rdac driver "rdac-LINUX-09.01.B2.74-source.tar".  I
think we tried to get the native RHEL4 multipath working but did not succeed
with our configuration.
