I upgraded to a new server after 12 years on a AMD Phenom II box with 16gb ram. I purchased a HP Z840 with Intel Xeon 2x 8core cpus and 64gb of ram. Based on VERY recent announcements about RHEL source support, I moved reluctantly from Alma Linux 8 to Redhat 9.
The process I used was to use a
fresh install of Redhat configuring it on a single boot drive. The system is obviously more robust and fast on boot, way quieter than the old box and i am not getting any errors on boot.
My Raid 5 array was recognized immediately and I was able to mount it using the UUID to fstab with ultra simplicity. Works perfectly! It is 4 by 1tb Western Digital Black server drives.
However, my Raid 1 array
did not get recognized. It is 2 Western Digital 4tb Black drives.

Can anyone tell me what is going on and why they are not connecting?
