Have you tried wrapping your disks inside LVM metadevices and then used those
for your ZFS pool?

I was just looking to see if it is a known problem before I submit it as a bug.
What would be the best category to submit the bug under? I am not sure if it is
driver/kernel issue. I would be more than glad to help. One of the machines is
a test environment and I can run any dumps/debug

I submitted a bug on this issue, it looks like you can reference other bugs
when you submit one, so everyone having this issue could possibly link mine and
submit their own hardware config. It sounds like it's widespread though, so I'm
not sure if that would help or hinder. I'd hate to bury the
What type of disks are you using?
I'm using SATA disks with SAS-SATA breakout cables. I've tried different cables
as I have a couple spares.
mpt0 has 4x1.5TB Samsung Green drives.
mpt1 has 4x400GB Seagate 7200 RPM drives.
I get errors from both adapters. Each adapter has an unused SAS

I have not tried that. I could try it with my spare disks I suppose. I avoided
LVM as it didn't seem to offer me anything ZFS/ZPOOL didn't.

Subject: [zfs-discuss] ZFS on JBOD storage, mpt driver issue - server
I've experienced behavior similar this several times, each time it
was a single bad drive, in this case, looking like target 0. For
whatever reason, buggy Solaris/mpt driver, some of the other drives
get wind of it, then hide from their respective buses in fear. :-)
Operating System: SunOS
I already changed some of the drives, no difference. The target drive seem to
have random character - most likely not from the drives.

Hi, you could try LSI itmpt driver as well, it seems

supports 8 devices at once or so.
You could also try more recent version of opensolaris

regarding mpt-driver (which still seems to have
Have you tried another SAS-cable?
I have. 2 identical SAS cards, different cables, different disks (brand, size,
etc). I get the errors on random disks in the pool. I don't think it's hardware
related as there have been a few reports of this issue already.
