Re: HP P400 RAID controller reporting p-disks incorrectly

* Harout S. Hedeshian:
Has anyone using the P400 controller experienced the ACU CLI utility
reporting the physical disks incorrectly? Whenever I do a show config
detail from the hpacucli (and hpaducli), it reports the three drives
as all being 0:0 with box 0 bay 0 and is reporting the model
information for the disk repeated. This is problematic as I can't
perform operations on the disks individually. The disks are SATA3G
(1.5G limited by controller). I am running the card on an Intel
S5000XSL motherboard in a supermicro chassis. I don't expect the card
to report bay/box given the non-hp backplane, but why all drives on
channel 0:0 with the first drive repeated?

Because the HP utilities are not able to resolve the drive location due to the lack of a HP backplane. If you look at a HP backplane you'll notice that there is more on it than just SATA/SAS connectors and power connectors, it contains some logic which tells the controller the slot numbers and the type of enclosure. Standard backplanes don't have this logic, so the HP utilities report all disks as 0:0.

I have a ProLiant ML350G5 with the original 6-slot (4+2 slots) backplane and a non-HP (Icy Box) 4-slot backplane (the Icy Box BP and the 4 slots of teh HP backplane are connected to a Smart Array P400, the 2 slots of the HP backplane are connected to a Smart Array E200), and ADU/ACU both show the same 0:0 for the disks in the Icy Box backplane.

What's also inconsistent is the drive show NCQ capable and enabled by
the controller config shows false...

Sure, since the Smart Array P400 only supports SATA 1.5Gbps (SATA1) which while not being a performance bottleneck doesn't support NCQ (which requires SATA2).
