DELL 6GBPS SAS HBA Device Driver for Rocky

Then you are all set. Have you rebooted the system?

Yes I have done lots of restarts after this installation … but I still get the same hardware errors. Should I roll back to centos 7 (I really don’t want to)?

Can you try unloading and then reloading the module and catch the output?

modinfo mpt3sas | grep -E ‘filename|version’
lsmod | grep mpt3sas
sudo modprobe -r mpt3sas
lsmod | grep mpt3sas
sudo modprobe mpt3sas
lsmod | grep mpt3sas

Then repeat this with megaraid_sas.

sudo dmesg

Toracat … following your command lines … This looks very promising. Thank you so much. There is no way I would have got this result without you. Many many thanks.
My adventure continues by learning how to control the tape drives in the terminal.
