- Recently I posted the following question on this newsgroup:
-
- : We are looking a converting a tape library of approximately 1000 9-track
- :from IBM's CMS operating system (also known as VM/SP, VM/HPO, VM/CMS, etc.)
- :to UNIX. The tapes on CMS are written in a variety of formats including
- :TAPE and VMFPLC2. The target UNIX systems are a RS/6000-970 and a SGI 4D/340S.
- :A 9-track tape drives is on the CMS system. Both the RS/6000 and the SGI
- :have 1/4 inch cartridge tape drive (QIC) and an 8mm cartridge tape drive.
- :All systems are joined together by TCP/IP.
- :
- : Any suggestion, solutions, or hints on migrating these tapes would be
- :greatly appreciated. A summary will be posted around January 25, 1993.

- I received several replies to this posting including a summary of a similar
- question asked last spring. Basically all the answers boiled down to senarios.
-
- Senario #1: Dump the data on the mainframe side and ftp the data across. Then
- reassemble it on the other side.
-
- + John H. Merritt (merritt@climate.gsfc.nasa.gov) has a shell
- script called "gettape" on the UNIX side that will help automate
- this process.
-
- Senario #2: Get a 9-track drive on the UNIX side then some of these tapes will
- be readable.
-
- + Tom Merrick(merrick@magnus.acs.ohio-state.edu) states that he
- he has programs that will read both tape dump and vmfplc2 tapes
- on an RS/6000.
-
- + Albert Lunde (lunde@merle.acns.nwu.edu) summary talks about the
- following tools:
- * "magtapetools" available via anonymous ftp from ftp.cs.vu.nl
- - a package of tools built to use "generalized mag tapes"
- that is, either a real tape drive or disk image files
- - includes C library for this purpose
- - cptp - copy between tape and disk images
- - survey - dump the start of each block in hex, ascii and
- ebcdic
- - rawtp - extract arbitrary data blocks from tape
- - ansir - read a single volume mult-file ANSI Standard
- Labelled Tape. It can handle F, U, D, S and V
- formats (V is for IBM tapes). Labels can be in
- ASCII or in EBCDIC.
- - ansiw - Ansiw writes a single volume multi-file ANSI
- Standard Labelled Tape in F- or U-format in ASCII.
-
- * cmstape - UNIX and CMS program to process CMS tape dump files
- - can read an image file created by readtape as well
- as direct tape
- - from c.s.u v07i008
- - according to mycroft@gnu.ai.mit.edu this is available
- from comp.sources.unix/volume7/cmstape
-
- * copytape - duplicate tape tape-to-tape or via disk image file
- by David. S. Hayes
- - from c.s.u v10i099
-
- * tprobe - copy any tapes
- - copy to remote drive
- - written with UNIX cartrige drives not 9-track tapes
- in mind
- - from alt.sources Feb 92
-
- * rmtlib2 - from c.s.u v18i109
- - remote mag tape library
- - This allows a program that uses Unix system calls
- to transparently use a file (usually a tape drive)
- on another system via /etc/rmt, simply by including
- <rmt.h>. It is particularly useful with tar and
- dd, and is supplied with GNU tar.
-
- * "ansitape"
- - read/write ANSI and IBM standard labeled tapes
- - originally designed for VAX-like ANSI labeled
- - also processes IBM labeled tapes in EBCDIC - does not use
- HRD3 or HDR4 labels on IBM tapes - I'm not sure what
- IBM record formats are supported.
- - reads but does not write multi-volume tape sets
- - may only write variable records ?
- - from c.s.u v08i099, v08i100

- Thank-you to everyone who responded,
- Philip Smith
