A little bit of background.
Sunfire V880 Solaris 9 8/03 Oracle with Veritas Volume Manager 3.5 attached
to EMC sym across 3 fiber channels.
When I run a vxstat -g data_dg below is what I am seeing. This is a newly
loaded server so I am thinking I might be missing some kernel params or
something. Being the only Sol9 machine I don't have much to go on. Other
2.6-8 Servers have read times near 10-31 ms. I read that anything over 35ms
is high.
