Can you show the output of 'devalias' at the ok> prompt?
If your disks are more than 4 levels deep inside the device tree
then the diskprobe loop in the boot loader won't see them.
If so, the following (untested) diff might fix the problem (adjusting
to an arbitrarily chosen higher recursion level of 10).
The easiest way to try this diff is to build a new release on another
sparc64 system (see man release(8)) and install that.
Alternatively, the following might work as a shortcut:
(If you're unsure about how to follow those steps, building a full
release will be easier!)
Compile all of /usr/src/sys/arch/sparc64/stand/ and run make install in
/usr/src/sys/arch/sparc64/stand/ofwboot, then copy /usr/mdec/ofwboot
onto a httpd server's webspace where a bsd.rd can fetch it from.
Boot the sun fire into bsd.rd and fetch the patched ofwoot to /tmp/.
Now mount your installed system's root partition at /mnt and its
/usr partition at /mnt/usr, and run:
/mnt/usr/sbin/installboot sd4 /mnt/usr/mdec/bootblk /tmp/ofwboot
to install the patched boot loader.
