Console Mirroring
Console mirroring allows a user on one serial port to monitor the service processor activities on another
serial port. This can be done on the locally attached HMC virtual terminal window or windows remotely
attached through modems. Console mirroring is supported on any combination of locally or remotely
attached monitors.
The serial port from which console mirroring is enabled is called the primary port . The mirror port is
determined when keyboard input is detected from one of the other two serial ports. From this point
forward, the service processor sends information to the active port and the mirror port only. Console
mirroring ends when the service processor releases control of the serial ports to the system firmware.
Console mirroring is supported on serial port 1 (S1), serial port 2 (S2), and serial port 3 (S3). Remote
attachment through a modem is supported on serial port 1 (S1) and serial port 2 (S2).
System Configuration
The following describes the configuration for console mirroring:
v
Service processor
v Modem connected to one serial port and enabled for incoming calls
v
Local HMC virtual terminal window connected to the other serial port. This local terminal can be
connected directly to your server or connected through another modem.
Console mirroring can be started by either of the following methods:
v Remote session first, then local session added:
1. Remote session is already in progress.
2. Remote user uses service processor menus to enable console mirroring, allowing both consoles to
be active.
v
Local session first, then remote session added:
