2. Boot the recovery system:
iris> b md0c:recover
This will boot a copy of the U
nix
kernel on the backup partition,
and run a program to copy the backup partition onto the normal
operating partition. After this program is finished, it returns control
of the IRIS to the PROM monitor, which displays its prompt:
iris>
3. Boot the terminal normally from the local disk (see Section 3.2).
4. Repeat the configuration sequence described in Section 5.3 .
If this procedure fails to return the IRIS to its former working state, the
problem may be more serious than a corrupted file system. Contact Silicon
Graphics field service personnel through the Geometry Hotline number listed
in Chapter 1.
If you are familiar with
U
nix
, you can use a 9600 baud ASCII terminal
connected to
Port 2
of the IRIS 3010 to log in as root . This may be useful for
diagnostic purposes in case the standard console textport is not functioning
properly. To connect an ASCII terminal to the IRIS, see Section 7.1.
5.3 Software Configuration
The IRIS 3010 software is based on the same System V U
nix
kernel used on the
IRIS 3020 and 3030. IRIS 3010 users do not necessarily interact with U
nix
,
however, because the terminal emulator program running on top of U
nix
provides an interface almost identical to the interface on IRIS terminals. The
terminal emulator interface is described in Section 5.2.
Because the IRIS 3010 is
U
nix
-based, the IRIS window manager runs on it.
The window manager is described in the IRIS User’s Guide, Version 2.1 .
An IRIS 3010 can be ordered with both XNS and TCP/IP Ethernet
communication capabilities. Configuration of the IRIS 3010 for network
communication is not necessary for normal operation, but some configuration
can simplify the process of communicating over the network and can increase
the terminal’s communication capabilities.
5.3.1 Configuration Tools
A number of files stored on the IRIS 3010’s hard disk allow for three kinds of
configuration:
• Startup environment configuration (see Section 5.3.2).
