Yes, if you use VM you are less likely of blowing your foot off should you
need to upgrade your system to, say, patch level 108528-23 and you are
fearful of the outcome, or not knowledgable enough to backup and recover
a veritas encapsulated system.

Many administrators have chosen a hybrid of
using SVM to mirror the root drive and Veritas to manage storage. I
suspect because they are placed in the same situation as I, required to
install production ready, redundant systems, but given inadequate training
on the tools to accomplish the task.

Hey, but take a look here.

Excellent documents. Now I am more afraid then before. Seems to be horror
stories using Veritas to encapsulate the root disk and then try and recover.

As other have stated SVM for boot drives and VxVM for storage :-)

Note veritas isnt only for volume mangement though if you plan on using
more advance features such as clustered file system quickio, Veritas
Cluster or Volume replication then ofcourse veritas is the way to go.

Every system in my organization that is SAN attached is handle by
VxVM/VxFS everything else is strickly SVM.

One thing to remember :

Veritas 4.0 does not need a rootdg.

Therefore you do not need to encapsulate your boot disks.

But !!! we have also limited access to SAN only for servers
using Veritas VM and FS

On the other hand we did not have any problems with recovering a failed
disk encapsulated with Veritas.

How's Solaris "forcedirectio" option compared to quickio ?

They are quite different things.

Unfortunately, I am unable to
explain the difference since
the information is confidential.

If you are a prospective customer
you can always sign an NDA with
Veritas and have a closed door
presentation of the product.

What else would you expect?

I don't know: a pointer to some documentation or statistics or even some
marketing bumpf, or is it a trade secret as to whether it is any good or
not? I doubt if many people are interested in the implementation details.
