Summary0001010: EL 8 kernels do not support all qla2xxx PCI IDs.
DescriptionUpstream EL8's kernel has support for a number of the PCI IDs covered by the qla2xxx driver removed. Requesting a kmod if possible for qla2xxx to add those IDs back.
Additional InformationPCI IDs impatced are listed under the qla2xxx driver on https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/considerations_in_adopting_rhel_8/hardware-enablement_considerations-in-adopting-rhel-8

Will work on it.

In the meantime, could you try installing the centosplus kernel (kernel-plus)? It is supposed to have the qla2xxx module.

My bad. Those removed IDs are not in the plus kernel. kernel-ml is the one you may want to try.

I'll see if I can get you a kmod package built tomorrow. Do you also need a DUD or just the kmod package?

I only need a kmod, since I don't currently boot from fibre-channel. Others who might want /root on SAN might appreciate a DUD.

In addition to restoring the removed pci_id's, do we want to enable the TCM_QLA2XXX Kconfig option? This option is enabled on RHEL7 kernels but is not set on RHEL8. I wonder if it's not set on RHEL8 as part of RH disabling support for older adapters, at which point do we want to enable it when building this module? Or do we want to leave it as not set?

Here's the relevant Kconfig:

config TCM_QLA2XXX
    tristate "TCM_QLA2XXX fabric module for QLogic 24xx+ series target mode HBAs"
    depends on SCSI_QLA_FC && TARGET_CORE
    depends on LIBFC
    select BTREE
    default n
    ---help---
    Say Y here to enable the TCM_QLA2XXX fabric module for QLogic 24xx+ series target mode HBA

There is an upstream bugzilla for that, actually, at https://bugzilla.redhat.com/show_bug.cgi?id=1666377

No technical reason is given. Target mode is an interesting and very cool feature, but I've never used it and it seems to have had issues in the past, so unless someone really wants it I would say that it might be best to leave it off.

Ack - built without TCM_QLA2XXX

I have built a kmod for el8.2 and uploaded to the testing repository:

kmod-qla2xxx-10.01.00.21.08.2-1.el8_2.elrepo.src.rpm
kmod-qla2xxx-10.01.00.21.08.2-1.el8_2.elrepo.x86_64.rpm

Please test and feedback here if things work as expected (or not)

yum --enablerepo=elrepo-testing install kmod-qla2xxx

For info:

$ rpm -q kmod-qla2xxx

Nice; thanks!

Downloaded and installed on the test host; I'll cable up to the SAN and assign LUNs and get back to you. So far though:

Great.

For reference, I have based the driver off the RHEL 8.2 kernel source code, rather than doing a backport from a kernel.org vanilla kernel. My reasoning being that RH (very) actively maintain this driver (ex the excluded dev_ids) so probably better to base off that in this case.

We will almost certainly need to rebuild the driver for each rhel point release, and often these rebuilds break backward compatibility. As above, we denote the build kernel in the release tag (e.g, el8_2) for reference.

Ok, cabled up the box to the SAN, set up a LUN for it, and ran bonnie++ on the LUN. Looks like it's working!

Brilliant. Moving packages from testing to the main repo now.

Please feel free to open a new bug if you have any issues.

We will likely need to rebuild the driver at point release time whilst RHEL8 is still in development phase.

Marking resolved :-)
