Yes I do. If had the choice I would not do any disk/storage work without
it. It is worth the money. I know of people that have said that it can
make system recovery more difficult. I frankly do not know what planet
they have come from. Veritas has literally helped me pull a rabbit out
of my hat repeatedly when it comes to system/file system recovery.
Depending on how you set up your volumes you have tons of options when
it comes to file system resizing, failed disk replacement, etc. VVM
allows you so much more flexibilty in managing disk than just about
anything I know (excluding native apps like HP and AIX's LVM). It
provides alternate disk pathing with vxdmp....

The thing that you have to realize is that VVM is not free. Either is
VxFS (Veritas' journaled file system). You have to have separate
licenses for base functions, RAID configuration and VxFS. Get a hold
of a Veritas sales guy or call Veritas and they will fill you in.

It is great stuff once you get your arms around it. You will never want to
go back to "regular" disk management after this (LVM on HP and AIX excluded).

Good luck! It is easy to install and easy to configure with the GUI.
CLI work comes a little later.
