Re: [Veritas-bu] NetBackup 6.5 index size

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.
