Dump parameters for HP DAT/DDS tape drive?

Post by Ricardo Mar » Fri, 24 Jan 1992 21:39:46



Hello Folks:

1) We have a DECSystem 3100 running with Ultrix 4.2.
   A HP SCSI DAT Drive, (HP 35470A) attatched to the DEC and
   uses 4mm cartridges (DDS 90mt, or 2GB in size).

2) This tape will also serve other machines via `rdump', machines like
   various kinds of SUN  machines, VAX machines and other DECS..
                    ^^^
3) Thanks a millon..

--- Ricky Marek.

P.S. I don't get `comp.unix.ultrix',`comp.unix.admin',`comp.sys.dec'
so please reply via e-mail, I will sumarize.

Hello Folks..

First of all, many thanks to all the ones that replied my posting, and
for the ones that didn't have the courage to ask, here are the answers

  Source              Dens.(bpi)        Size (ft)

- From HP guys:            6,250        (Try the maximum size, it must work)
                                                                  ^^^^

- Digital on TLZ          61,000        12,500 (60mt tape)
                                        18,300 (90mt tape)

- SUN Sources             50,000        60,000 (90mt tape)

- Hebrew University   56,974,055         1,960 (90mt tape)

Some said about for a 5GB tapes, use 3,000,000 size for a 60mt tape
without setting the density (Nigel Metheringham)

I didn't have the chance to test these parameters, but You, may enjoy them.

1. dump parameters for HP 4mm DAT Tape Drive

I've just installed an HP 4mm DAT drive on an RS/6000.  This
drive purports to store 8GB on a single tape with dynamic
compression.

Can anyone recommend a set of dump parameters (block size,
tape size, and density) for this tape drive?  Thanks.
