Want to transport volume from HP to Red Hat

[ronlevyca]

We have an XP20000 SAN and an rp7420 that runs a database residing on the SAN.
We would like to use Oracle transportable tablespaces to write out the database
onto a XP20000 volume on the HP system, and perform a vgexport/vgimport sort of
process wherein we could access that XP20000 volume onto our Red Hat Linux system.

Obviously, we are doing this because our database is about 2TB and we are trying
to convert from our rp7420 to an HP Proliant. We are pretty sure we can write
out the database in such a way that an Oracle database on the Linux host can read it, but the kind of schedule we will need to follow for this cutover doesn't allow for us to copy 2TB over the network to the new Linux machine.

Is this even possible, or is it completely impossible?

Not possible if the source volume is a HP LVM volume... HP LVM and Linux LVM are different animals - they look very similar on the surface (share many of the same commands etc.) but they are certainly not compatible.

The only situation in which this works is where you are using Symantec (Veritas) VxVM - VxVM has the concept of "portable data containers" which can be moved between certain platforms. Of course VxVM costs $$$ for both HP-UX and RHEL.

This sounds astoundingly promising, thanks! The documentation even mentions Oracle Transportable Tablespaces which is what we were testing!
