We are currently having an issue bringing up the second port on the Twin Blade system, both IB switches are populated in the chassis. We are using RHEL 5.5 x86_64 & OFED 1.5.1. I wanted to find out if the Mellanox firmware 2.9.1000 is supported on the AOC-IBH-XQD module?
Please contact Supermicro Tech Support (support@supermicro.com) for the v2.9.1000 firmware. The new firmware will fix this compatibility issue with OFED 1.5.1.
