The purpose of this email is to ask if I can configure multiple IP addresses per physical interface on an F330.
Sure. It's very easy using the "alias" option to ifconfig(1). For example, the sequence:
ifconfig e0 192.1.1.1 ifconfig e0 alias 192.1.1.2
will put a couple of addresses on the e0 interface.
If it is possible I did not see reference to it in the manuals.
It's described on the na_ifconfig(1) man page in the command reference guide for Data ONTAP 4.3.X. If you have a NOW account, you can obtain this electronically from:
http://now.netapp.com/knowledge/docs/crq41.pdf
the filer is a F330 running 4.0.2c (?) and I have NFS over TCP turned off.
Hmmm. I don't know offhand when the multiple IP addresses on a single interface support was formally introduced. There's a chance it was post 4.0.2c, although I'm not certain. If your na_ifconfig(1) man page doesn't mention the "alias" option, you may need to get a hold of a newer software release. Again, you can download that from the NOW web site if you have an account there.
