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.

Subject: upgrade to 6.1R1
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??
