zfs discuss - Jul 2012 - Has anyone switched from IR -> IT firmware on the fly ? (existing zpool on LSI 9211-8i)

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.

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.

Ok, and your LSI 1068E also had alternate IR and IT firmwares, and you went from
IR -> IT ?

Is that correct ?

Thanks.

Correct.

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

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
