A 3270 is required for the installation and configuration of z/VM. Once
the system is installed and configured (including VM TCP/IP), then the
system console on the HMC is sufficient to OPERATE the system. Telnet can
be used to access the system so that you can perform additional system
configuration. The requirement to have a 3270 for TCP/IP configuration is
listed in the General Information Manual ("TCP/IP for z/VM Hardware
Requirements", p. 15 in z/VM 4.2 version).
The addition of an ifconfig command in z/VM 4.3 can reduce the need for a
3270 even more, but permanent changes to your CP or TCP/IP configuration
will require a 3270 so that you can edit files (unless you are big on
line-mode editing or are a CMS Pipeline expert). If you are using
DirMaint, it is much easier with the menus, requiring a 3270 (also
mentioned in the General Information Manual).
On a personal note, I have never understood the aversion to having 3270
access for all LPARs on all CECs. Given the value you receive, the IBM
2074, or similar non-IBM products, are worth the relatively small expense.
In an emergency, local 3270 access will be your best friend. I would not
want to try to wade through a TCP/IP console log looking at traces using
the HMC...
