Exabyte dump command

[Steven Gutfreund]

1) What are good parameters for dumping to an Exabyte?

My OEM tells me to:

dump ucdfs 54000 /dev/nrst1 6000 /dev/rsd1a

I don't know what a good density is, but the SONY tapes I have are 106
meters (347 feet) long.

2) If I put five dump files on one tape, how does one do a 
   restore of the third dump file?
