MHGH28-XTC issue

Hi,

I am trying to set up IB

I have several MHGH28-XTC HCAs

1 appears to work but others do not.

The working HCA has rev A3 on the label the others show A4.

Running CentOS on the server with OFED.

I can see the adapters when I run lspci they all show:

[root@localhost ~]# lspci | grep Mel

01:00.0 InfiniBand: Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] (rev a0)

But when I run ib_devinfo I get:

[root@localhost ~]# ibv_devinfo

No IB devices found

The working device shows:

[root@localhost ~]# ibv_devinfo

hca_id: mlx4_0

I was hoping I could change the firmware to get these other cards working but they don't even appear?!?

Thanks for any help.
