How to clone/duplicate System Disk (RZ29B) ?

We tried booting from VMS 7.3-1 CD ROM and doing VMS BACKUP/PHYSICAL to the same type of disk but the cloned disk did not boot (this ised to work for OSF Unix)?


TIA,

try to look for the command
backup/image first_disk: clone_disk:

do some research

Give more details: do you want to duplicate system disk to other internal disk of the same server or to another server? Or you want to have backup on tape?

Try btcreate/btextract of the filesystems you want to duplicate.

Mohammed,

a Tru64 Unix disk does not use an ODS file system, so "backup/image" will NOT work.

Slution that works for me is:

dd if=/dev/rdisk/dsk0c of=/dev/rdisk/dsk1c bs=1024k

Thank you all !

I have written a Perl script to clone a
normal (non-cluster) system. Send me mail
if you would like to get it.

- backup/image is an OpenVMS tool avaiable in standalone image which 'the old guard' often used to copy like disks.
Dd is indeed the normal Unix choice.

- fyi... and interesting document in this space:
