dump question...

Hi there -

I am running Tur64 Unix V4.0F on an Alpha DS10 with a DAT TLZ10 tape
drive on it.

I have been appending my daily dumps onto a single tape, but reached
the end of tape much sooner than expected. I believe that I must
have the tape size or density computed wrong. (the description for
the dump command is pretty cryptic in the DLZ10 manual.)

Anyway I am using a 24GB DDS-3 tape. For the density, I am using 61000.
i calculated the tape size to be 229758 (or 3 * 153172 - as described
in the manual).

so my dump commands look something like
  dump 1udsf 61000 229758 /dev/nrmt0h /dev/$fsys

and for some other calculations (determining the % of tape used up) i
figured the tape size to be (24G) = 25200000000

are my numbers all wrong?

thanks for your help

daniel
