@bearcat That statement was for the internal p420 RAID controller on the DL380p Gen8. I do not know what IR mode is. However following a few guides online I was able to use the HP SPP disk to boot into the raid controller. Using "hpssacli controller slot=0 modify Hbamode=on forced" and then confirmed that the controller was in HBA mode, also show in POST.
When I use my PCI-e LSI 9211-8i HBA card, I have no issues with the install or running DSM. However after some reading I have found that if ANYTHING is in a PCI-e slot on the server it will spin up two fans baseline to 35-45%. makes a massive racket and wasteful power usage.
When I use the p420i controller in HBA mode, everything seems to be installing as expected however, the install will not see any HDDs on the array. If I'm understanding things correctly this is due to the hpsa.ko driver not being present in Xpenology. When trying to use IG-88's extra.lzma, I will get the boot screen saying to go find the server but NOTHING ever shows up on network. I have checked my router and it never even pulls an IP. So it breaks something.
THANK YOU for the time to try to help me figure this out!
