We have two ECRs we'd like to get some feedback on:

*	#17831 (Gateway names should be case-insensitive)
*	#11325 ("vsvr move -f filername" is case sensitive, "vsvr set
vsvrname" is not)

Currently, filer names and cluster names are case sensitive, just like
the underlying hostname on which they are based in BSD.  Vsvr names and
CIFS share names are case insensitive, and are converted to upper case
before they are stored in the cluster database.

Convenience would dictate that filer names and cluster names be case
insensitive.  However, that imposes restrictions that do not exist for
the underlying hostnames in BSD.  Do we have customers who rely on the
names being case sensitive?  What do customers expect?

Thoughts?

ChrisV & Charissa
