Here's a better link below.
I have seen enough bad things happen to pool devices when hardware is
changed or firmware is updated to recommend that the pool is exported
first, even an HBA firmware update.
Either shutting the system down (where pool is hosted) or exporting
the pool should do it.
Always have good backups.
Thanks,
Cindy

Correct.
LSI 1068E has IR and IT firmwares + I have gone from IR - IT and IT -
IR without hassle.

Ok, and your LSI 1068E also had alternate IR and IT firmwares, and
you went from IR - IT ?
Is that correct ?
Thanks.

Hi Jason,
I have done this in the past. (3x LSI 1068E - IBM BR10i).
Your pool has no tie with the hardware used to host it (including
your HBA). You could change all your hardware, and still import your
pool correctly.
If you really want to be on the safe side; you can export your pool
before the firmware change and then import when
your satisfied the firmware change is complete.

Import: http://docs.oracle.com/cd/E19082-01/817-2271/gazuf/index.html

We have a running zpool with a 12 disk raidz3 vdev in it ... we gave
ZFS the full, raw disks ... all is well.
However, we built it on two LSI 9211-8i cards and we forgot to
change from IR firmware to IT firmware.
Is there any danger in shutting down the OS, flashing the cards to
IT firmware, and then booting back up ?
We did not create any raid configuration - as far as we know, the
LSI cards are just passing through the disks to ZFS ... but maybe not ?
I'd like to hear of someone else doing this successfully before we
try it ...
We created the zpool with raw disks:
zpool create -m /mount/point MYPOOL raidz3 da{0,1,2,3,4,5,6,7,8,9,10,11}
and diskinfo tells us that each disk is:
da1 512 3000592982016 5860533168
The physical label (the sticker) on the disk also says 5860533168
sectors ... so that seems to line up ...
Someone else in the world has made this change while inflight and
can confirm ?
Thanks.
