ILo2 flash issue.

[JAC_4]

I have a customer that has purchased a DL580 G5 server. The customer requires a flashing down of the ILo2, from 1.42 to 1.22. The problem is that I cannot get the server to accept 1.22, the lowest I can go is 1.30. Can anyone help with this issue, is it possible to flash down a G5 model to 1.22?

Thank you.

Downgrading firmware is not recommended, and mostly in a brand-new server. There are known bugs corrected on ILO 1.42 and 1.43.
If you're going to install Windows for example, the boot process could stop on BOOT.INI countdown and you have to press Enter for booting process to continue.

I found this customer advisory. According to this, you can try decrementally downgrading the ILO firmware. 1.30 > 1.26 > 1.22.

It is highly recommended to keep the latest revision unless absolutely necessary to downgrade.

Hope this helps.

Thank you for the replies. I have tried using the process of 1.30->1.29->... This did not work either. Apparently the processor in this ILo2 version does not allow a lower ROM than 1.30.
I know I have lowered the ROM for ILo2 in a DL380 G5 for this same customer (1.22). I understand the updates are there for very good reasons, but customer requests are fulfilled whenever possible. In this case it does not appear possible, unless an engineer out there can give some insight into this question.

Again, thank you for the replies.

The DL580G5 is fairly new server so, iLO2 firmware versions 1.29 and earlier do not support this model. That's why you cannot downgrade the iLO2 firmware to a version earlier than 1.30.

By the way, why do you want to use firmware version 1.22?

No versions of iLO 2 below 1.30 are supported on that host (DL580G5). Do not downgrade below the minimum supported version.
