How to Downgrade HP MSA70 from 2.28 to 2.18 connected to a P812 Controller

I have a HP MSA70 storage array connected to a  P812 controller.

The MSA70 is running firmware 2.28 which is not supposed to be used when connected to the P812 controller, only when connected to a MSA2300 contorller.

The ONLY firmware updates I can find on HP.com are to update the firmware WHEN connected to a MSA2300 controller, etc.  Nothing for when it's connected to a P812.

How do I go about doing this??

You use CP010425.scexe with the firmware update DVD which just happens to be Linux.

What version are you looking  for?  2.18, 2.16 are at http://tinyurl.com/plage7v . The maintenance DVD probably has the right one too since it's for ProLiants rather than for re-badged Dot Hill SANs.

I can find the right version but I can't find any updates that will update it via the p812

CP010425.scexe does not work with the P812 as the HBA?

I could quite believe that from experience, you might have to borrow a P400 or similar card that's about the same age as the enclosure for it to work with the update CD.
