[SunHELP] Veritas vs. DiskSuite

[Jarrett Carver]

At one time Sun offered Solstice Volume manager, which was simply a 
repackaged Veritas. This was not a free product, and is not the same as ODS. 
I beleive it was just a way for Sun to charge the Gov't more money (since 
that has been the only place I saw it being used). If I remember correctly 
even when Sun was selling Solstice VM, it was always a version behind the 
current Veritas, so you ended up paying twice as much for less of a product.

This was apparently their same approach with Solstice Backup which was just 
a repackaged Legato.

I also recall when Sun's HA software first came out it required ODS, but the 
current versions play nicely with Veritas.

Maybe I just don't know anything, but didn't Sun license disksuite code
from Veritas??? Or didn't Veritas write disksuite for Sun, using
VolumeManager as a codebase? Something like that is tickling the back of
my head, which leads me to think from a performance perspective they're
pretty much the same.
In either case, in order to mirror the root partition, you'll have to do a
little number called encapsulation: this basically creates a small slice
on the root disk that "points" to the actual structures on the two mirror
devices. It's not difficult to do, but it may require a little advance
planning: you need to have, I think, two free slices on your root disk
for a total of about 10 sectors. Don't quote this on me - it's been a
while since I've done it - but I believe the two products are more-or-less
the same in most regards. There's a great book from Sun Press called
Blueprints: Guide to High Availability which talks about both products and
provides a nice step-by-step instructional for doing this.
