Hi Roy,
The drive order issue is likely to be persistent mapping.
It can be disabled using lsiutil.
I found it was enabled by default on early cards, and disabled on later
ones, but changing the firmware doesn't change the origional setting.
What model are the disks ?
Did the origional system also use expanders ?
Mark.

believe that you would be the first one using them with ZFS (those

time?
Yes
Are the drives in both chassis failing?
Yes
Supermicro is affordable and pretty basic but I fear using them in any
other way than what they were designed for. Is there something on
those chassis that you were supposed to configure? Those devices are
designed and tested with very traditional raid an jbod setups in
mind... think if there is something you didnt do but you would need to
do in case of setting up a traditional jbod storage...
We use supermicros on some rather largish servers, and they're very stable.
Thee issue here is probably a driver or controller issue, see
http://www.mail-archive.com/zfs-discuss@opensolaris.org/msg32079.html
Back when I had my problem I was testing all the drives 1 by 1 and all
the cables, and all the different combinations of things... it was all
useless. when something so fishy appears beware of the controllers. To
make a memtest is a good idea, you could let it running over night, if
memory corrupts probably there is some hardware problem in the
motherboard.
Thats all that comes to my mind... is the hardrive order swapping
between reboots?
But my bet is supermicro, or the way you configured the jbod utility.
The controller is running a firmware without RAID support, so everything's
JBOD. The storage chassises don't have any configuration, they just have a SAS
expander, that's all.
Vennlige hilsener / Best regards
