TermDSM Requirements
The following hardware is required when using TermDSM:
The minimal mainframe configuration of a HP 3000 Series 900 computer.
The system and each DTC connected and configured as nodes on the LAN.
At least one pair of serial interface/connector cards installed in each DTC, with at
least one port of each connector card connected to an asynchronous device.
The following loopback connectors supplied with each DTC (for DTC 16 and DTC 48
only):
25-pin connectors for SNP cards (24400-60216)
25-pin connectors for modem cards (02345-60010)
3-pin connectors for RS-232-C direct-connect cards (30148-60002)
5-pin connectors for RS-422 direct-connect cards (30147-60002)
The software required to use TermDSM is included with the MPE/iX operating system.
The MPE/iX operating system must be functioning properly for TermDSM to work.
User Capabilities and Security Levels
The functions of TermDSM commands are restricted by three different security levels.
Each security level is associated with the capabilities necessary to use commands of that
level. The security levels correspond to the Online Diagnostic Subsystem.
Table 3-1 lists the security levels and the corresponding capabilities. When a user issues
a command, TermDSM checks the user’s capability list to verify that the user is
authorized to use commands of that security level. If the capabilities of the user are
insufficient, the command is not executed and an error message is displayed on the
terminal.
NOTE Users without any of the above capabilities cannot use TermDSM.
A Word of Caution
Some TermDSM commands abort sessions and can cause a loss of data. If used
incorrectly, the commands can unnecessarily disrupt or abort user sessions.
