Steven,
I have upgraded 4 of our F760's from 5.3.7 to 6.1R1. These 4 have 8 shelves of 18 gb drives in 2 volumes each (1 online, 1 snapmirror). The only issue is that older disks are VERY sensitive under 6.1. There is a specific reference to possible problems spinning up older drives in the docs for 6.1 - definitely read it. We had a number of disks refuse to spin up after the disk firmware upgrade step - almost lost a volume. Be prepared to power cycle the entire filer and disk shelves - this helped us get past a multi-disk failure that almost lost a volume. We ended up with a couple of drives in a broken state, but sparing took care of those.
Also, there are annoying messages about configuration issues that do not show under earlier versions. In our case, 6.1 complains about the placement of our gigE NICs in certain slots. We've known about this "issue" for some time, but did not choose to take downtime to optimize it. Haven't figured out how to shut them up yet.

I currently have three filers in a mixed environment, NT and SOLARIS, two at 1.4TB the other is 2.5TB. I plan on using them in a cascading mirror configuration. Does anyone have experience with upgrading to 6.1R1 and its operation? Since 6.1R1 is still in "First Customer Shipment Releases" I was wondering if anyone has experienced operational problems with 6.1R1??
