LSI MegaRAID 9341-4i controller supported in Proxmox VE 8 ?

[JensV1999]

Hi

I'm currently researching in updating from PVE 7.4-17 to 8.

I currently have the LSI MegaRAID 9341-4i Raid card installed and is detected and working in proxmox 7 as you can see from the pictures below :





When I upgrade to Proxmox 8 should I be worried that my card will not be detected anymore? And get situations like this :
- https://forum.proxmox.com/threads/p...n-ssd-connected-to-avago-9341-4i-card.113182/
- https://forum.proxmox.com/threads/proxmox-can´t-see-the-virtual-disk-provided-by-lsi-raid-controller.81722/

because when updating, I can imagine the OS image will change from Linux-5.15.131-2-pve to something higher or at least a new kernel version with Debian Bookworm and the device stops communicating with the kernel.

I also read multiple things on the internet, like it has a build-in driver and doesn't really matter which version of Debian/ubuntu you are running. (but why did I need to install the driver then ) . Other say there card stops working ... So I'm kind of lost in the information and hope to get a clear answer on how this actually works =D

PS : I don't have access to a spare card I can test it with but are there maybe ways to test it without doing damage ?

Thanks in advance

I have the same issue. I use hardware raid and I am on PVE 7.4. The megaraid drivers on https://hwraid.le-vert.net/wiki/DebianPackages havent been updated so unsure what to do. Anyone resolved this ?

any update on this..?
mine is a megaraid 9441-8i (Dell)
thought I was buying a 9440-8i broadcom megaraid

megaraid-sas is broken in 8.2.2 (https://forum.proxmox.com/threads/p...-8-1-4-to-8-2-2-enterprise-repository.145915/)

Would putting it into IT mode get the card working?

 

[frank68]

Card is in IT-Mode (Controller-BIOS-Setting HBA). In 8.1 (Kernel 6.5) everything is fine.

I have the card running in 8.2.2 but I do have performance issues on JBOD since 8

i'd love to get my 9440 into IT mode...can you send a link?
edit - PS the BIOS is not showing the card; there is no PCI entry visible...

Hi gents! I just tripped over this thread having exactly the same concerns/challenges. Can anyone confirm that the LSI MegaRAID controllers do work and perform under Proxmox VE8.2 in JBOD/HBA mode? If so, did you have to install one of the ancient drivers available on the Broadcom page or did it just work out of the box?

Unfortunately I am also not in a situation, where I could test anything easily, looking into migrating over to Proxmox and want to rebuild my entire setup.

I have Broadcom (LSI) Raid Controller and HBA in use in some servers.
The latest and not so old 96xx, 95xx and 94xx are all running normally.
I've read a few times about problems with the 93xx and 92xx chipsets, but they still run fine with the 6.5 kernel.
You can still run PVE8 supported with the 6.5 kernel, even if the default kernel is now 6.8.
You can still use old cards for testing, but I recommend at least a 94xx chipset for productive use.

Thanks for sharing your experience. I've got a 9260 running currently so might have to look into upgrading it then.
