Making the jump from VMS system managment to ULTRIX system managment
sure is fun.  Here is a little problem that some of you expirenced
super users might be able to help with.

I am doing a level 0 dump of my file systems to TK-70.  The file system
in question is under 200mb.  A TK-70 is supposed to hold 295mb.  Why 
does dump require 3 tapes?

  DUMP: Estimates based on 1200 feet of tape at a density of 10240
BPI...
  DUMP: This dump will occupy 17987 (10240 byte) blocks on 2.12 tape(s).

--------------------------------


Have I got something setup strange, does the system think its a TK-50?
Should I be using B,d or s options?  Is dump just a tape hog? Or should
I just stick to VMS?
