ahci with 6 3Gbps ports, Port Multiplier support

[leona]

Hello,
I have a backblaze with port multiplier and i have installed the latest version FreeBSD 8.2-RELEASE-p5/FreeNAS-8.0.3-RELEASE-x64 (9395).
any disks installed on port multiplier are detected.

on the message log:
ahci0: AHCI v1.30 with 6 3Gbps ports, Port Multiplier not supported.
please help.

Leon A.

Port Multiplier support is a bit in AHCI capabilities register. If it is not set, it can't be set by driver. But I've seen cases when BIOS update changed that (disabled it on my case).

hm i guess ahci0: is the first sata Port on the board himself where is you multiplier connected ?
try camcontrol devlist -v in shh and post the output pls

AFAIK backblaze used several SiliconImage SATA cards, not on-board AHCI controller with port multipliers.

HI,
in this version "FreeBSD freenas.local 8.2-RELEASE-p6 FreeBSD 8.2-RELEASE-p6" the kernel is not compiled with ataahci_load="YES" and so the driver ahci.ko does not exist.

Looks like you've mixed everything possible. ataahci.ko is an old AHCI driver. It is not used on newer systems. ahci.ko is a part of the generic kernel now and doesn't need loading. As soon as you see that message about multiplier, ahci.ko is obviously loaded.

If controller doesn't have port multiplier support, it will see only device on the first port multiplier port.
