[SOLVED] Drives Missing after reboot

[DracoPurple]

So I've migrated my UNRaid server (6.8.3) to new hardware and added new drives with a HBA.
Everything was working fine and I even rebuilt my Parity earlier yesterday without issue.
I went to setup VMs and realized that the HVM was disabled.
I rebooted and enabled SVM in the BIOS and booted back up.
Now all 4 drives on my HBA are missing.
Thinking that the setting change was the culprit, I disabled the setting and rebooted to no avail.
The HBA and drives show after the BIOS splash screen with all the drives and no errors.
I'm at a lost as everything was going smoothly before with no obvious issues.
Please help

Some Marvell controllers, especially the 9230 which you're using has known issues with iommu enable, this works for some.

It's still enable on the diags posted.

1) edited /boot/syslinux/syslinux.cfg

2) added 'iommu=pt' to the line containing 'append initrd=/bzroot'

You absolutely magnificent person.
Thank you so much!
This worked like a charm.
I had to use the 'Intel' version despite on AMD but no complaints here.
The HBA is a stop gap anyway until I get a large LSI HBA.

I must have taken the diags after re-enabling HVM (SVM) but IOMMU was on from the start.
In anycase, thanks again.

This just saved me from the madhouse.

I owe you a bottle of Scotch.

In retrospect, I may have had that backwards.
