/etc/dump parameters for EXABYTE 8200

Tue Jan 30 05:37:55 AEST 1990

As part of a PARITY systems unit, we have an EXABYTE 8200 tape drive
advertized to be able to store 2.3 Gbytes on an 8mm tape.  However, I have
no information on what parameters to use for dumping.

In particular, I would like to know what to use for:

  b :  # blocks/write (assuming 512 bytes/block)
  d :  density in bpi
  s :  tape length in feet

/etc/dump has no defaults for 8mm tapes, and if I use the regular
defaults, I will be greatly underusing the capacity of the drive.
