March 11, 201610 yr Hello all, trying to give unRAID a whirl here. Trying on an HP Z800 FF825AV (x2 Xeon 5540), 24G ram and having issues. Thankfully the 5520s are not too too old and support VT-x, I believe VT-d (it says VT-d2). The USB setup and bootup goes fine, and I log into the http://tower without issue, but the two hard drives are grayed out and I cannot select them. I caught during bootup that the AHCI bios is not installed, and this HP also has a built in RAID controller (LSI). I figure the hardware RAID is giving unRAID the issue. Some of the LSI info that pops up or via digging up-- MPTBBIOS-6.22.00.00 MPT SAS BIOS C1068E, embedded, RAID 0 (IS), RAID 1(IM), RAID 10(IME) capability. SAS address 50014380:0571245A Pretty sure this is what is causing very slow VM performance, but google is not being giving in regards to finding info on how to enable AHCI and/or put this embedded controller into some kind of IT mode. I've navigated all over the BIOS, and all over the LSI settings (ctrl-c at the right time during boot up). -- edit -- google brought me back to this forum- https://lime-technology.com/forum/index.php?topic=12767.0 Looks like I'm on the right track (already disabled boot support). Guess I will slide in the windows HDD, download some stuff and give IT mode a whirl- or via a linux live boot USB as I shouldn't do this from a drive plugged into the controller...
March 11, 201610 yr Community Expert What license are you using? If it is the Trial version, unplug all of the sata connectors and then connect only the two hard drives that you are going to be playing with. (The Trial version has a limit on the number of devices that can be connected to the hardware and it does work properly if that limit is exceed.)
March 11, 201610 yr Author Trial version, and only have 2 hard drives plugged in. Using the post I linked, the LSI SAS adapter bash that finds any controllers pulls up nothing, I'm thinking this is more for the PCI card controllers and not the motherboard embedded stuff. Going into Windows Device Manger, it shows Intel ICH8R/ICH9R/ICH10R/DO SATA RAID Controller (with exclamation mark needing updated drivers- having windows scan for it now) and also shows LSI Adapter, SAS 3000 series, 8-port with 1068E. Additional note: Proxmox works on this PC, though the VMs run very very slow despite enabling write-back cache, allocating lots of cores, RAM etc.
