control,
and
the
power-on
self-test
that

Hardware
Management
Console
(HMC)
Overview
and
Setup
The
HMC
uses
its
connection
to
the
processor
subsystem
to
perform
various
functions.
The
main
functions
of
the
HMC
include:
v
Creating
and
maintaining
a
multiple-partition
environment
v
Detecting,
reporting,
and
storing
changes
in
hardware
conditions
v
Acting
as
a
service
focal
point
for
service
representatives
to
determine
an
appropriate
service
strategy
Note:
The
HMC
is
shipped
with
the
Eserver
pSeries
655
and
is
the
main
interface
for
configuring
and
managing
resources
on
this
system
through
the
HMC
virtual
terminal
window.
Virtual
terminal
window
refers
to
the
operating
system
session
on
a
particular
window.
You
can
have
up
to
16
virtual
terminal
windows.
All
the
tasks
you
need
to
maintain
the
interface,
the
underlying
operating
system,
and
the
HMC
application
code
are
available
by
using
the
HMC’s
management
applications.
