Redhat 8.8 on UCS C220 M5 Rack Server

[Defdefred]

After the issue waiting for Cisco provided drivers for RedHat 8.4 last year, I have the same issue with RedHat 8.8!

I need driver for ucs-cxxx-drivers.4.x/Linux/Storage/Intel/Intel/LSI/C600

Drivers are limited to RedHat 8.6 in the 4.2 series of drivers, last 4.2(3g).

Drivers are removed in the 4.3 series after 4.3(2a).

What are we supposed to do?

For all desperate Linux user on Cisco UCS servers...

You can suppress the need of the megaSR driver by using the AHCI mode in the BIOS.

The LSI softraid disk layout is compatible with a standard gpt disk layout.

But both disk are block to block identical, so you need to erase the second disk.

My solution:

1. ReaR backup + remote copy backup
2. Set BIOS to AHCI mode
3. Boot Rear ISO
4. clean disk2: fdisk , dd, what you want...
5. reboot on the internal disk
6. dracut failed =>

   # modprobe ahci

   # lvm vgchange -ay

   # exit

7. rpm -e kmod-megasr-18.03.2022.0626_el8.6-1.x86_64
8. subscription-manager release --set=8.8
9. yum upgrade
10. # cat /etc/modprobe.d/anaconda-blacklist.conf
    # Module blacklists written by anaconda
    blacklist ahci
    # rm /etc/modprobe.d/anaconda-blacklist.conf
    rm: remove regular file '/etc/modprobe.d/anaconda-blacklist.conf'? y
    # dracut -f --regenerate-all
11. reboot

When all is well configured, you can configure the good and reliable linux softraid raid: https://access.redhat.com/solutions/4194011
