How to Set Up Console Mirroring
Console Mirroring Concepts
Console mirroring is a way to provide the customer a view of what the person working
remotely from the Service Console is doing on the system. When mirroring is active, the
Service Console and the BUMP Console are logically identical, and both are tty0 (tty1 is
disabled when the mirroring starts).
Mirroring only works on the two serial ports, S1 and S2, and their respective ASCII consoles
or terminal emulators. It does not work on the graphical devices. The BUMP Console can be
either local (no modem connected) or remote (through a modem connection). Remote
console connection must be established through dial-in (BUMP does not dial out). The
Service Console is usually remote, connected through a Hayes-compatible modem on the
S2 port; however a local, directly attached console at the S2 port can also be supported.

When mirroring is active, the customer on the BUMP Console and the support personnel on
the Service Console both see the same output on their screens, and either one may enter
characters. One person can even start typing and the other finish it. For example, the
support personnel may log in as root on the Service Console, and the customer may enter
the root password on the BUMP Console. Therefore, the remote support personnel do not
need to know the root password.
Console mirroring is possible during the following SystemGuard phases: Stand-By, Init and
Run-Time (AIX running).
The prerequisites for console mirroring are:
•
Remote Service Support 1
•
/usr/share/modems/mir_modem file present (for mirroring when AIX is up)
