Yes, this is a boot block issue.
Code:
# man installboot
...
     installboot bootblk raw-disk-device

So it is actually
Code:
# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/cwtxdys0

/dev -> device
rdsk -> raw disk
You can look at the raw disk device and the bootblock file on the install medium
Code:
# ls -l /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/cwtxdys0

and even check their file type
Code:
# file /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/cwtxdys0

The installboot command copies the file to a certain area on the disk (that is not visible in the file system).

Between the backticks there is a sub command
Code:
# uname -i

The shell runs it and replaces the backticks portion with the result, like this:
Code:
# ls -l /usr/platform/SUNW,Sun-Blade-2500/lib/fs/ufs/bootblk /dev/rdsk/cwtxdys0
