I face this error
ERROR:/pci@1,600000/usb@b Last Trap Fast Data Access MMU Miss
If you went down+ to it from a running OS, then there are tons of data registers that are full of extraneous data and the MMU miss error is classic. It simply says to you "I am confused so go do it right".
You could consider doing an init 0 (as root user) from a running OS, or (a better approach) you could consider modifying your OBP settings for auto-boot so that the system always stops at OBP instead of automatically proceeding to an OS.
If you went up+ to the prompt from a powered-down state and interrupted boot to get there and still see this error message, then you would have a hardware issue. Very rare.
When I boot from the [hard] disk and log in to the solaris even more I can't see the DVD driveIt's not uncommon to have an empty optical drive "missing" if it is empty. Volume management wouldn't have a volume to manage. If you have difficulty in such a circumstance when there is a disk in that optical drive, then the volume just hasn't been mounted yet.
Fast Data Access MMU Miss generally means something is not being found. And it usually revolves around upgrading the OS and not upgrading the firmware. So try either upgrading the firmware or downgrading the OS.
