[carl brunning]

Not sure if this help you 
But i had this problem on nexenta and the fix was the following

	in the /kernel/drv/mpt_sas.conf i unrem the line with mpxio-disable="yes";

	then reboot the system

	this fixed it for me and then i could see all my ssd when before only one show in the gui list

this was for Samsung disk as well

hope it is the same problem for you 

thanks

CArl

The worst case would be if the firmware image is signed and encrypted, which I doubt. There is a workaround for that too if that would be the case anyway.  I'm not sure whether those firmware images have a real file system (such as yaffs for Android devices) or are just a solid binary file.

Here are a few pages that I found:
