Try the hardware compatibility list for the card on Redhat's website. Second
choice, the manufacturer's website. The issue is the driver.
My question (rhetorical), why do you want to use an OS that is recently
released and still bleeding for a backup server? I understand upgrade
headaches, but backup servers need to be rock solid.

Hello,
Have any of you deployed RHEL 8/Centos 8 and would be willing to share what
HBA card they are using?
Anyway, attempting to purchase HBA card and looking for a way to figure out
what will work without having access to the tape library. Lets say that you
don't have access to the tape device, but you have a server that have RHEL 8
installed. You plug in a SAS HBA card in the slot and bring it up and them on
the console, you want to check if the card is supported by the operating system.
What would one check? This is what I have done and not viable test
without the storage system:
[root@eng-backup02 ~]# lsscsi -g
[0:2:0:0] disk DELL PERC H710P 3.13 /dev/sda /dev/sg0
[0:2:1:0] disk DELL PERC H710P 3.13 /dev/sdb /dev/sg1
[1:0:2:0] tape IBM ULTRIUM-HH6 E4J1 /dev/st0 /dev/sg2
[1:0:2:1] mediumx QUANTUM UHDL 0091 /dev/sch0 /dev/sg3
The /dev/sg2 and /dev/sg3 only show up with the tape library attached. If
I de-attach the tape, but leave the HBA card on the system, the device
disappears.
I have also attempted this:
lspci -nn
The problem with this is even a HBA card that I know will not work when I
attach the tape library is detected by the operating system and will be listed
on lspci result. So I can't ask someone remote to use that to separate
supported to unsupported.
So what else can one do the achieve this objective?
Regards,
William
