RedHat 7.6\8.0 and LSI SAS 2008 controllers

Post by Ingvarhost » 2018/11/23 05:05:06

Starting with versions 7.6 \ 8.0beta, RedHat has disabled support for SAS controllers on the LSI SAS 2008 chip. However, in Fedora 29 with the kernel 4.18, the controllers work. So, RedHat simply assembled the mpt3sas kernel module without the support of these chips. How do I activate support for these chips back?

Have you actually tried 7.6 on this system? If a driver is deprecated, it does not mean that it will be immediately removed.

You can get the 7.6 packages with yum update --enablerepo=cr

RHEL 8 beta is a different beast, let's concentrate on CentOS here.

Thanks. I updated on the test server using yum update --enablerepo=cr and rebooted the server. Now I have a kernel 3.10.0-957.el7.x86_64. The output of lspci shows that the mpt2sas driver is used. The controller works and the disks on it are visible and accessible. Ok, it means that I can update on all servers to 7.6 after the release.

And yet, is there any procedure for reconfiguring a kernel module?
