Re: SAN w/ multiple paths on IBM bladecenter

[shane stixrud org]

A couple of things 
a) will the installation method you outlined work via pxe and kickstart 
or is user intervention required?

b) I had already tried the noprobe option and specified the ql2xfailover=1 
in the options box, however I still saw two drives.. any ideas?

Thanks.
