Using vxstat:

Can someone explain to me what the difference between Operations Read/Writes
as opposed to Blocks Read/Writes? How is the Avg. Time calculated? We have
a read only database (for the most part - we update the database weekly).
Why am I seeing writes to my volumes even on days when I am not writing
to the volume? Are these just parity bits or something?

I am running Volume Manager 2.5 on Solaris 2.6.

Thank you.
