Thank you, Eduardo, for replying me.
However, still I'm caught by the problem as follows.

root device (default sd0a): sd0*
			    ~~~~ I typed sd0* instead of sd0d
dump device (default sd0b): none
			    ~~~~ 
file system (default generic): 
root on sd0b
~~~~~~~~~~~~ It's on /dev/sd0b

I wonder if it's OK that I copied miniroot-14P.fs into swap by
"dd if=miniroot-14P.fs of=/dev/rdsk/c0t0d0s1 bs=8192" because
miniroot-14P.fs was not included in the netbsd/sparc64 current
archived file. I found it somewhere(maybe for netbsd/sparc) and
used it.
