tape to tape copy

[Gregory Bollella]

I am trying to make copies of VMS tapes on a UNIX system.  We have
VAX 11/780s with BSD 4.3 and SUN 2,3,&4s with Sun UNIX 4.2 Release 3.4,
Sun UNIX 4.2 Release 3.5, and SunOS Release Sys4-3.2 respectively.
Each machine has at most one tape drive.  I have tried dd and tcopy 
with most permutations of their options to no avail.  If anybody knows 
of a solution I would appreciate e-mail.  If a solution does appear I will 
post.  Thank you,
