Thanks for taking an interest. Unfortunately I did have failmode=continue, but
I have just destroyed/recreated and double confirmed and got exactly the same
results.
zpool status shows both drives mirror, ONLINE, no errors
dmesg shows:
SATA device detached at port 0
cfgadm shows:
Just a thought, but how long have you left it? I had problems with a failing
drive a while back which did eventually get taken offline, but took about 20
minutes to do so.

I've left it hanging about 2 hours. I've also just learned that whatever the
issue is it is also blocking an init 5 shutdown. I was thinking about setting
a watchdog with a forced reboot but that will get me nowhere if I need I reset
button restart.
Thanks for the advice re the LSI 1068, not
Yeah, sounds just like the issues I've seen before. I don't think you're
likely to see a fix anytime soon, but the good news is that so far I've not
seen anybody reporting problems with LSI 1068 based cards (and I've been
watching for a while).
With the 1068 being used in the x4540 Thumper 2,
doesn´t solaris have the great builtin dtrace for issues like these ?
if we knew in which syscall or kernel-thread the system is stuck, we may get a
clue...
unfortunately, i don´t have any real knowledge of solaris kernel internals or
dtrace...

What version of Solaris / OpenSolaris are you running there? I remember zfs
commands locking up being a big problem a while ago, but I thought they'd
managed to solve the issues like this.

Apologies - I'm daft for not saying originally: OpenSolaris 2009.06 on x86
Cheers

It's a generic Sil3132 based PCIe x1 card using the si3124 driver.
Prior to this I had been using Intel ICH10R with AHCI but I have found the
Sil3132 actually hot plugs a little smoother than the Intel chipset. I have not
gone back to recheck this specific problem on the ICH10R (though I can),
Ok - in an attempt to weasel my way past the issue I mirrored my problematic
si3124 drive to a second drive on the ICH10R, started writing to the file
system and then killed the power to the si3124 removable drive.
To my (unfortunate) surprise, the IO stream that was writing to the mirrored
Whether ZFS properly detects device removal depends to a large extent on the
device drivers for the controller. I personally have stuck to using
controllers with chipsets I know Sun use on their own servers, but even then
I've been bitten by similar problems to yours on the AOC-SAT2-MV8 cards.
