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

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.

 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.

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.
