Thats good then, since we're going to 9.1P19.

I think we're all set there.

This is a good thing to know, mine are all at 3.1.2 version.  I'll see
if there's a newer version and plan on upgrading them all ahead of
time if I can.  Thought I might not, since 3.1.2 is the latest version
supported with OnTap 8.3P2, so the 9.1P19 will give me upto SP version
3.9 to install.

Thanks for this info, I'll certainly look into this ASAP.

Great idea, I can start this tonight I think.
