I now want to upgrade the fw from IR to IT.
Is there any practical reason for doing that?
I want to avoid the risk of the IR fw writing any metadata to the disks which already
hold a software RAID.
Is it not the case that the IR fw may mess with the disks (I read a comment suggesting it might)?
Regardless, I want to update to fw 20 - the card is on 18 now.
I have a SAS9212-4i with a very ancient IR firmware -- and the thing is, it
just works perfectly as a dumb SATA controller, including full SMART access to
connected disks -- what else is there to ask from it?
This is a fair comment which I will consider. ATM I avoid booting this card with the
disks connected.
(no TRIM pass-through, but that's kind of "by design" with these cards, and I
doubt it's fixed in the new firmware)
Not an issue for me.
If I'm not mistaken it's IT that is the simpler firmware for when you don't
need the hardware RAID, but considering the above, and how cumbersome and risky
the flashing process is, what am I losing by staying with IR?
Yes, I expect the IT fw is simpler, and I hope more stable too as it mostly stays
out of the way.
Anyways here's one more HOWTO on flashing that may or may not be more helpful
than the ones you listed:
