To follow up my own post... The error 84 failures were caused by a
flaky SAN interswitch link. We repaired our ISLs and these problems
went away. Veritas tech support was very helpful in helping us
troubleshoot this issue.

It turns out that we didn't need MP1 broke include/exclude processing on
Solaris clients. We turned on some debug logging and Veritas has
confirmed that's broken. If you're in need of include/exclude
processing, do not upgrade your clients to MP1 - it was apparently ok in
We're also having issues with Windows backups that Veritas has
confirmed (we weren't the first customer to see this one). We've seen
the scheduler request a backup of the same drive twice in the same
stream. If you look at the job in the Activity Monitor, you may see W:
appear twice in the same job. It's also possible that a separate job
may be backing up W: as well.

These were our SAN issues. We fixed the SAN and the throughput is back
to what we were getting before.
