Sorry for the basic question, but I'm a Solaris guy trying to warm up
to AIX. Any help would be greatly appreciated.

We have an old 7017-R86 (S80) that's running 4.3.3. I need to put it
on EMC storage and EMC recommends that I install 'Maintenance Level
4330-11' first.
Where do I get it and what's the "best practice" way to install it
safely?

Thanks in advance.
