1. lofs is probably a bad idea - mount them directly into a zone
lofs is the only supported option for vxfs.

While lofs is the only officially supported option, mounting directly
in the zone can be accomplished with a work-around. see:
http://seer.entsupport.symantec.com/docs/276134.htm
The customer will only accept officially supported options on this (i.e.
lofs).
Why exactly would lofs be a bad idea? What is the downside to lofs rather
than directly using VxFS? With lofs they get the benefit of the ability
to share
one filesystem among multiple zones (not at the same mount point in the
global zone).
But is there anything that would increase/decrease performance by using
lofs?
Is there a major performance difference to running a database with its
storage
on lofs vs. VxFS vs. RAW?
