Copying Mainframe Volumes

Hercules390 - General mailing list
Is there a methodology to copy full volumes (whether z/VSE, z/VM or z/OS) directly from the mainframe into the emulated DASD format used by Hercules? or does a  full volume backup need to be converted to an AWS tape; FTP transferred; then mounted as an input tape and restored on the Hercules system?

Loading the new DASD volume

Next you need to create a full volume dump file on your mainframe and
convert it to AWSTAPE format using the tapeconv.jcl job in the
Hercules source directory. The AWSTAPE file can then be downloaded in
binary format to your PC where it can be defined as a virtual tape
drive in the Hercules configuration file.

A standalone program can now be IPLed into Hercules to restore the
volume image from the virtual tape onto the formatted virtual DASD
volume.

You could try OMA instead of AWS. You create a xxxx.tdf file that is mounted to an OMA tape device. I've never used this so I don't know if it will work. Flex-es has documented the version of TDF files they support. http://support.funsoft.com/flexman/fsims100-faketape10-fsi-007-000-010-003.html

Depends on your circumstances. If you are running on a fairly modern
OS-style operating system such as OS/390 and up, and have enough disk
space on the running system to hold a compressed copy of your volume,
then you can easily use cckddump, found ready-to-go at
http://cbttape.org/ftp/cbt/CBT541.zip

It requires APF authorization, but if you want full volumes that is
going to be a requirement for pretty much any tool. It can compress
the result using gzip or bzip2, so depending on your data, the
resulting file may not be all that huge. Obviously text compresses a
lot better than binary, but bzip2 is still impressive. And unused
tracks are not dumped, by default. It's a very impressive program.

You can FTP the result of cckddump to a file on your host (Windows,
Linux, ...) and just name it appropriately as a CCKD DASD file. Best
to run a checksum at both ends, or at least make sure the byte counts
are identical. No tape in the picture.

If you are talking VM or other non-OS OSs (heh), then you will
probably need a (virtual) tape based solution as others have
suggested.

RE: Copying Mainframe Volumes

Hercules390 - General mailing list
In reply to this post by Hercules390 - General mailing list


  *   Is there a methodology to copy full volumes (whether z/VSE, z/VM or z/OS) directly from the
  *   mainframe into the emulated DASD format used by Hercules? or does a  full volume backup need to
  *
  *   be converted to an AWS tape; FTP transferred; then mounted as an input tape and restored on the
  *   Hercules system?

There is a program named cckddump (I think it may be on the CBT Mods tape if not on the Hercules site).  It dumps a volume to the format Hercules expects.  It has to run APF Authorized.   This is the proc I use to do the dump and ftp it to a UNIX box.  I did not get to follow the whole thread, so this may be redundant.

Note, SP3PARM is is a simple minded program which dumps the parm string to DDNAME OUT.   Left as an exercise for the reader 😊

This doesn't answer your question, but
you can probably skip creating an AWS
tape and instead copy the DFDSS
dump into a RECFM=VB using IDCAMS
REPRO then ftp with rdw option, and
then use a different utility (RDW2UND?
or COPYFILE) then another IDCAMS
REPRO to recover the original DSS
dump file.

Simplest is RECU2AWS but uses time and I/O:
1. ADRDSSU DUMP to disk data set.
2. RECU2AWS to another disk data set.
3. Down load binary.  FTP is many time faster than IND$FILE.
4. Define new disk with DASDINIT.
5. ICKSADSF INIT new disk because DASDINIT doesn't INIT.
6. ADRDSSU BUILDSA restore tape image to new disk.

Another option is AWSADR:
AWSADR is a flaky ADRDSSU exit that intercept the output of
an ADRDSSU DUMP and writes to a disk data set as an
AWS tape image.
More complicated to get to work than RECU2AWS above but does't
copy the data twice.
Other steps are the same.

Another option is CCKDDUMP:
It reads a zOS disk volume and creates a CCKD disk image.
It currently has a 4GB limit so disks larger than 3390-3
that cannot compress down to 4GB or less have an issue.
Excluding some data sets may get you under the limit?

zVM is not covered with the above.

I have done it in a much simple manner. I just copy the Windows file
representing the voume and paste it using Windows Explorer (While the
mainframe is shutdown, off course).

Actually, I have a question. Why are
you looking for such a thing? Is it
because you are unable to automate
some of the above? If so, which bit?
If it's the MVS on Hercules bit, I use
a Windows batch file called "runmvs"
which IPLs MVS, runs a batch job
and then terminates, allowing a lot
of automation.

 To get around the rdw issue, I tersed the dfdss file before ftp'g it across. Takes a lot of cycles though on the source.
