Undefined Terminal Types
If you specify an undefined terminal type from the DEFINE TERMINAL option menu, the
menu prompts you to enter a valid terminal type. The menu redisplays until either a
valid type is entered or the user exits the DEFINE TERMINAL option.
Resetting the Terminal
If you enter a terminal type that is valid (according to the DEFINE TERMINAL option
menu) but is not the correct type for the ASCII terminal being used, you may be unable
to read the screen, use the function keys, or use the Enter key. Bypass these difficulties
by pressing Ctrl-C to reset the terminal. The screen display which results from this
resetting action depends on the mode in which the system is being run:
vOnline Normal or Maintenance Mode - The command prompt displays.
vStandalone Mode or Online Service Mode - The terminal type is reset to dumb, the
Diagnostic Operating Instruction panel displays, and you are required to go through
the DEFINE TERMINAL process again.
Running Online Diagnostics from CD-ROM
Consider the following when you run the online diagnostics from a server or a disk:
vThe diagnostic CD-ROM disc must remain in the CD-ROM drive for the entire time
that diagnostics are running.
vThe diagnostic CD-ROM disc cannot be ejected from the CD-ROM drive once the
diagnostic programs load. The diagnostic CD-ROM disc can only be ejected after the
system has been powered off and then powered on (standalone mode), or after the
diagnostics program has terminated (online concurrent mode). The diagnostic
CD-ROM disc must be ejected before attempts to load the diagnostic programs
again.
vThe CD-ROM drive from which diagnostics were loaded cannot be tested.
vThe SCSI adapter (or circuitry) controlling the CD-ROM drive from which diagnostics
were loaded cannot be tested.
Running Standalone Diagnostics from a Network Installation Management (NIM)
Server A

client

system connected to a network with a Network Installation Management (NIM)
server is capable of booting standalone diagnostics from the NIM server if the client
system is registered on the NIM server, and the NIM boot settings on both the NIM
server and the client system are correct.
Notes:
1. For NIM clients that have adapters which would normally require that supplemental
media be loaded when standalone diagnostics are run from CD-ROM, the support
code for these adapters must be loaded into the directory pointed to by the NIM
SPOT from which you wish to boot that client. Before running standalone
diagnostics on these clients from the NIM server, the NIM server system
administrator must ensure that any needed support for these devices is loaded on
the server.
2. All operations to configure the NIM server require root user authority.
