I have a few HP Blades Gen7 equipped with QLogic Infiniband cards IBA7322 which I would like to use with CentOS 8. The problem I have is that I cannot find the right drivers for them. All the information I find is either old, or the links don't work (e.g. the marvell download links).

I can see the card with lspci but other than that I didn't have any luck turning it on (so to say).

Can anyone point me in some sort of direction with this problem?

  • Did you check to see if the drivers were dropped due to the hardware's age? RHEL often removes drivers for ancient hardware from its latest kernels. Commented Aug 18, 2020 at 18:48
  • I didn't see that card on the list... If it is still supported how would i know?

The first thing to do is to get the PCI vendor and device IDs for the hardware in question. Your card appears to be 1077:7322. A quick look at the Linux Driver Database tells me this card uses the ib_qib driver.

I took a look through the RHEL documentation of removed drivers in RHEL 8, but did not see this driver. However, I fired up a RHEL 8 VM and the driver is no longer present and is not enabled in the corresponding kernel configuration. It is present in RHEL 7 though.

What people usually do in such a circumstance, in order to use the old hardware, is to use the elrepo repository, which for RHEL 8 contains the missing ib_qib driver (and several other drivers that Red Hat dropped). For example:

dnf install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm
dnf install kmod-ib_qib
  • thank you for your help! I did install the driver but I still cannot see the infiniband card as active. How do I activate it after the driver installation?

  • Is the module loaded? Does lspci -vv show it being used? Commented Aug 19, 2020 at 14:06
  • I am editing my original post to show you what lspci -vv says.

  • Oh, you have an HP-branded card, not an OEM QLogic card. What's the actual vendor and device ID for your card? Commented Aug 19, 2020 at 15:36

after many many trials my friend threw a hail Mary and recompiled the 4.19 kernel on Rocky 8.5 and enabled the qib driver. It was there all along it was just not compiled in the default kernel.

Now we got the old QLogic card working again. It is connected to a (gasp!) Mellanox Infiniband Switch that is running the Subnet Manager.

The nodes are able to communicate at 40 Gbps between them and they are also able to communicate with the much newer 100Gbps Mellanox ConnectX5 cards too.

All is good in infiniband-land now!

Hope this helps someone and if there are any questions I'll do my best to answer them. Just keep in mind that I am in no way an expert in these things. Just a guy that had to figure something out and make an old equipment relevant again!
