[Lustre-discuss] Problem with Qlogic driver instalation,

[Jeffrey Alan Bennett]

Hi Eric,

I personally prefer using Linux Device Mapper Multipath for these Qlogic 2462 adapters. I think your disk array is supported out-of-the-box, you only need to uncomment /etc/multipath.conf. Take a look at it, it's more flexible than Qlogic failover.

About the missing lustre files, you might be missing Kernel Source RPM for your distribution, make sure you have kernel-devel and kernel-headers RPM packages installed.

I don't think Lustre has anything to do with your HBA drivers, so your issue with compiling the Qlogic driver is more likely to be resolved by searching qlogic.com knowledge base.

Take care

Subject: [Lustre-discuss] Problem with Qlogic driver instalation,

I have lustre installed on a CENTOS or rocks system
right now i am trying to install the vendor qlogic drivers so i can enable failover mode.
right now i have two block devices for each lun
ie /dev/sdr and /dev/sdai point to the same LUM on a 6141 array
there are two things that i have noticed the Lustre kernel sources seem to have broken links
the kernel-2.6 link points to a non existant directory
also the install of the qlogic driver fails.
i am hoping that someone else has run iinto this problem, i am using pretty comon HW
this is a QEM2462 FC card
and a sun 6240 blade.
here is the error i get.
