Count yourself lucky you haven't used LVM on AIX. I keep
dreaming of ways to get the SAs to install Storage Foundation onto our AIX
boxes. =)

I second Ed’s
recommendation of Veritas Volume Manager (VxVM). Not just for
NetBackup but for most filesystems (including those for >terabyte
databases). The options one has for controlling things such as
buffering, block sizes etc… are important for databases. Moreover since it
allows you to grow/shrink filesystems on the fly it is a great tool for
Production environments where downtime Is hard to get. Finally since
it allows one to do software RAID in environments where hardware RAID isn’t
available it has that added benefit.
Most Sun Solaris shops
of any size use VxVM. Many HP HP-UX shops use VxVM even though HP
has its own Logical Volume Manager (LVM) but many still use LVM. On Linux
most Enterprise folks use LVM which is very much like the one on HP-UX.
AIX has one called LVM that I haven’t used.
Using Windows for very
large enterprise class environments simply isn’t an option for most folks due to
scalability issues.

I use Robocopy alot,
but I feel that the product may have been ill-advised by someone who thought we
needed the product, when clearly we have proven this is not the
case.
Robocopy and Diskpart
:-) works like a charm!

That's because you're a Windows guy and
the product certainly doesn't function on Windows like it does on Unix. If
you're a Unix guy, you'll see the limitations of Windows and its lack of a
volume manager very quickly.
My catalog is in a volume manager and yes,
we've grown it. We've bounced a lot of our storage around between
SAN frames as well as expanded volumes. On the other hand, my Windows
admins do nothing but bitch and moan when they have to do the same thing.
Linux, HP-UX, Solaris, VMS - all move data nicely around. Windows, well,
just say no.
Robocopy is not an alternative to a volume manager
:-)

Build your catalog filesytem
using a Logical Volume Manager, such as Veritas Volume Manager (Storage
Foundations) on a SAN attached LUN. As your catalog grows you can grow both
the LUN and the filesystem hot, without an outage.
Or, if you have
availability of a recent Enterprise class array such as the HDS USP-V, you can
build it on a DP (Dynamic provisioned) LUN (aka thin provisioning)
The
array presents your server with a large fixed size LUN, even several
terabytes, but only occupies as much disk space as needed, initially, then
auto allocates disk as needed.
Personally, I'd just go the volume
manager route.
