What version of HP-UX do you have?
You could look at using DRD if 11.23 or 11.31

Hi,

with dd you can clone disk. You need at least the same size with original disk. As the device file will be changed, you must change lvmtab information as explained below thread:

or you can mirror/ux to clone boot disk.

DRD is the better solution.

If using "dd" you need to go to maintenance mode and vgexport/vgimport vg00 to reflect the changed h/w path.
