Cannot Install Proxmox on T610 Poweredge with H700 PERC card

[Brodesps]

Hi all,
Having trouble with installing Proxmox on a RAID-0 VD via my perc card (h700), every time I try and get started with the Install media, it keeps I/O erroring at the 3% Creating LVs screen. I need to install via the PERC as I can't use onboard SATA and the raid controller at the same time.
I have tried two different USBs, all ports on my T610, with no luck. I am on the latest firmware for my machine (6.6.0 BIOS) and downloaded a fresh Proxmox ISO 9.2-1 last night (29th May).
If anyone can help, very appreciated.

Welcome, @Brodesps
As a test, I would try to install some other Linux distribution - to check whether the issue is PVE related or rather a general one.

Are they Dell drives that are backing the PERC? IDRAC (even iDRAC6) should give you some idea if things are OK as Onslow suggested. Seems like there might be other problems with the HW.

There are multiple documented issues with modern Kernels (>6.2) with LSI based controllers on older (pre Haswell) platforms, stemming from bios mapping issues- older kernels were much more foregiving. You can try to shoehorn their firmware into memory by playing around with kernel cmd line (eg, pci=realloc, pci=realloc=off, pci=nommconf, etc) but when I ran into this issue I spent entirely too much time trying to "fix" it without success.

The answer from my perspective is if you MUST continue using such old hardware, stick to PVE7 (early versions of pve8 work too, but you would need to be judicious about pinning the old kernel.) yes its unsupported but it will work flawlessly.

yes its unsupported but it will work flawlessly.

"unsupported" is not just a random tag. It is an active risk. And this is true also for my homelab.

Did you notice there were NINE PVE-kernel releases (in "no-subscription") alone during this crazy May 2026? Guess how many you get for Version 7...

Obviously you're fine with that. Obviously I am not. You may know how to handle that special case. When you recommend that to a "New Member", without knowing anything about the knowledge-level of @Brodesps and the intended use case (commercial?) I need to mention the above and recommend: no, do not do that!

 

[alexskysilk]

lets put things in perspective.

OP wants to run pve on a 15 year old server. it is clearly NOT for production use. what, exactly, do you suppose any such "risk" actually entails?! regardless of the NUMBER of kernels released since, NONE of them open up features relevant to ops use case, and many security fixed were backported. Not all and no further, but considering the use case I doubt thats an actual concern.

You and I do have a fundamental different point of view and we give different recommendations. I believe that is ok. Let the user decide

Thats an observable fact but when you say

unsupported" is not just a random tag. It is an active risk.

I need to mention the above and recommend: no, do not do that!

It is explicitly a different message; I believe you come from a genuine place and want to help people- please expound on WHAT you feel is the risk is here. I think that would settle both your point and mine.
