IBM 6C4 Undefined Terminal Types, Resetting the Terminal, Running Online Diagnostics from CD-ROM

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.
