Hi! I wanna use TrueNAS-SCALE-25.04.1 as VM on vmware ESX 8.0 with MegaRAID SAS 9460-16i (as a backup storage) as pci device. I made it as passthrough device with no issue

Could you please help me to understand what could be on issue here? firmware? some additional controller or kernel parameter?

Guessing it a RAID controller and not true HBA?

jbod mode is not true hba and could also lead to trouble. If possible crossflash it to it mode.
