Unable to find RAID 5 VD during CentOS installation

Post by Pijush » 2020/10/02 10:07:58

We have a Dell T30 server with Dell H310 RAID controller. We have configure RAID 5 with three HDD. The problem is that, we are unable to find RAID 5 virtual disk during installation of CentOS 8.2.2004.

RHEL 8 deprecated a large number of old RAID controllers and this would be one of them. If you are lucky then ELRepo may have a Driver Update Disk to add back support via a kmod package that can be added at install time.
CentOS 6 will die in November 2020 - migrate sooner rather than later!

CentOS 5 is dead, do not use it.

Hi,
which package may work for me? and how can I install kmod packages during installation?
Thank you.

I wrote some scripts which will figure this out for you here:

https://sourceforge.net/projects/pci-ids-info/files/

A post a couple of weeks ago in this forum announced it:

viewtopic.php?f=54&t=75703

Boot the system with a live CD for any distro which works, download and unpack the files from the above link, and then do:

Code: Select all

./map_hardware_to_drivers.pl PciIDsFile ""            >/tmp/mhtd_default.txt
./map_hardware_to_drivers.pl PciIDsFile CO8_installer >/tmp/mhtd_co8i.txt
./map_hardware_to_drivers.pl PciIDsFile CO8_kernel    >/tmp/mhtd_co8k.txt

diff /tmp/mhtd_default.txt /tmp/mhtd_co8k.txt
Which will show you which drivers in the running system are absent in CentOS 8. (Refer to the
the README, it is a little complicated because of built in vs. modules). Then do:

Code: Select all

./elrepo_driver_for_missing_centos8.pl elrepo_module_pci_info.txt CO8_kernel
which will tell you if there is an ElRepo driver for any of the missing drivers.
