If you specify the dasdfmt option "-d cdl", which is the default and stands
for "compatible disk layout", dasdfmt writes a volume label to disk.
This label in the third disk block contains the label identifier "VOL1" and
a 6 char volume serial. The default for this volser is "0X????", where ????
is your device number.
You can specify your own volser to dasdfmt or change it afterwards with
fdasd.
Only ECKD DASDs formatted with "cdl" and partitioned with fdasd are visible
to OS/390. Each partition appears as a single data set
(e.g. LINUX.V0X1234.PART0001.NATIVE).
If you already use DFSMSdss to backup your OS/390 disks, you can use it
also
to backup your Linux disks. There is no need to have two backup solutions.

Please respond

Port
DFSMSdss requires a volume serial to dump a dasd. The volume initialized
as
Linux volume does not have a volser. How does DFSMSdss recognize the
volume
for dumping?
Thanks.

If you have an OS/390 at your box you can do a full volume backup using
- DFSMShsm
- DFSMSdss
- OFFLINDR.
With VSE you can use
- FASTCOPY
and with VM you can use
- DDR
Without using above systems you have also the following possibilities:
- TSM
- tools like AMANDA, HOSTDUMP, ...
- tar, cpio, nfs, scp, ... to tape or another Linux using a little script
and the cron daemon
