you may also use "rcp" to simply remotely copy data or file from one system to another by configuing .rhosts.

I strongly suggest you:
a) read the manuals at http://docs.hp.com
b) consider attending HP-UX education courses
c) read the very good document on etiquette to be used in hte forums: http://66.34.90.71/ITRCForumsEtiquette

Hi David,

You did not specify what kind of DISKS are you referring to. If they're just simple SCSI attached disks -- then you have a wealth of tools available to you: dd, remsh, cpio, tar, ftp, etc..
.
However if you are using SAN disks -- then you can ask your SAN Administrator to make the disks "accesible" to both servers. Of course only one server can have it on an LVM/VXVM control at any one time. After being written to on one server - you can "deport" the Volume/Disk Group that the disk(s) belong and "import" it on the other server... a very nice approach to doing large backups which I also called the "Floating Disks" strategy -- you save a ton on so called SSO/DDS (shared tape drive) licenses on most backup software.
