I am not a Veritas expert, but I figure that the reason folks ask for
Veritas in a zone is because they want all the behaviors they are used
to on a stand-alone system.
One reason for raw devices it to avoid the filesystem overhead. And
with Veritas, they'd want to use QuickIO if using VxFS to simulate raw
speeds while using filesystem symantics and administrative benefits.
So the questions I have are:
Since there is a single VM, filesystem and cache, and kernel, would it
be sufficient to create the necessary filesystem(s) in the global zone
and deliver them to the non-global zone? Is Oracle or any other
application going to see lower performance if they application is
running in a non-global zone? Is an application such as Oracle hidden
from some of the device specific accesses or properties that the
reduced privilieges on a NGZ present?
So, is it necessary for Veritas to provide feature support in a NGZ?
I guess the same questions apply to DirectIO on UFS?
Thanks

If my memory serves me correct, I have done this in the past with a UFS
filesystem. I think all I had to do was to define the device name with zonecfg.
Off the to of my head something like -
[In zonecfg]
add device
set match=/dev/vx/mydg/rdsk/disk100
end device
Note: my veritas is rusty these days :)
