Problem with mpt(4) and Infortrend RAID

[Rong-En Fan]

[please CC me, thanks]

hello,

I also have a mpt(4) (LSI21320) here and a 
SilverStar TN6016 RAID (which is also produced
by Infortrend). OS is FreeBSD/amd64 (on EM64)
5.3-RELEASE-p5. Hardware is IBM x236.

mpt0: <LSILogic 1030 Ultra4 Adapter> port 0x5000-0x50ff mem
0xcdee0000-0xcdeefff
f,0xcdef0000-0xcdefffff irq 52 at device 1.0 on pci4
mpt0: [GIANT-LOCKED]

If I map two 1.6T logical drive to the same channel
with different LUN, I got similar problem like yours
However, if I do ONE of following will solve:

  1. set the channel to 160MB/s (sync clock is 80Mhz)
  2. map 1 logical drive to 1 channel (I have two channels
     on raid)

I'm using 2 now, but I just did a little io traffic
(< 5MB/s and < 30secs) then got following messages:

mpt0: time out on request index = 0x5e sequence = 0x0000156d

By the way, if I use 320MB/s and plug the RAID into another
Adaptec 29320LP (ahd(4)), it fails when bus scanning. On the
other hand, 160MB/s is fine.

any suggestion about this?

Thanks,
