how to copy raw data from one disk to another

[Nappy_1]

I want to copy a raw data from one disk to another disk on a hpux 11iv2 server. i guess that the command "dd" is the right choice.

i'll use this command "dd if=/dev/rdsk/c0t0d0 of=/dev/rdsk/c0t0d1".

is that correct with the good options? is there another command better than dd?

Hi,

Yes, dd is good choice, to improve performance defines a convenient block size:
#dd if=/dev/rdsk/c0t0d0 of=/dev/rdsk/c0t0d1 bs=1024

By HP Mirror/UX could be another safe/fast way to do this.
