EMU Firmware update on disk shelf?

[PDP-Fan]

I have an EVA4000 and I have been ordered to upgrade all the disk and shelf firmware to the newest versions. Disk have been easy to upgrade... no problem there.

But how do you upgrade the EMU firmware of the disk enclosure? Is there a procedure anyway? Or is this supposed to leave as it is?

Disk shelf: 14 bay FC Disk Shelf, SPN:245307-002 Model: AD542A

I will appreciate all kind of information like where to get the firmware and how to upgrade it... or a definitive information that this is not possible ;-)

The firmware in the disk drive enclosure's EMU is automatically flashed by the controller as soon as it detects a mismatch (e.g. after you upgrade the controller firmware or attach a new enclosure).
You can check the load-progress on the EMU's 7-segment display.

upgrade the controlers to firmware 6220, _(is the newest now) and the emu is upgrade.

Here is a thread that deals with this.

And here is a link to the docs for the SAN Design Guide and a ton of other relevant stuff.
