Re: [zfs-discuss] Has anyone switched from IR - IT firmware on the fly ? (existing zpool on LSI 9211-8i)
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

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.

We created the zpool with raw disks:

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.
