Hook it to the scsi bus and use it as additional space. be sure to give the disk
a free address, not the ones used by the build-in disk (0?) or the interface (7).

THen do an ioscan to see where the disk is.

As far as I know scsi, they are intended to be hot-pluggable, hence you even
might give that a try. Only when you twiggle with the scsi termination, there
might be scsi-errors which might cause run-time problems (this is common scsi).

Once hardware is installed, use `sam` to setup the disk. The nicest thing is to
add the disk to a volume-group (vg) or create a new one. and create
logical-volumes (lv) on the disk.

If you hook more than one disk, you can set them all up in a software raid with
this: all disks in the same volume group and create logical volumes over the
disks in the raid you like. I'll adivce raid0 (striping) for size or raid 1-0
(striped mirror) for availability, better not use raid 5 or other.

Once you can create filesystems, either copy one of the filled filesystems to a
new space or create aditional data space.

You might even try to extend current lv-s and their filesystems if the disks are
all in the same vg but that only if you will take the risk.

unfortunatly not: M$Windows definitly does not know about the HP-UX
'partitioning' (i.e. logical volumes). Linux does not jet know about it (might
be work in progress). And HP-UX does not know the partition-scheme of the other
2 parties. Only if the other system runs HP-UX, preparing the disk (and dumping
data there) is an option.

In the end, there is also linux for PA-Risc. Debian has a distro. Some details
are on http://www.openpa.net/systems/index.html
