Recovery Operations for Communications Subsystems

Some general troubleshooting guidelines are:

Examine the contents of the event message log for the subsystem. For example, the WAN subsystem or Kernel subsystem might have issued an event message that provides information about the process failure. Event messages returned by the WAN subsystem and SWAN concentrator are described in the WANMGR and TRAPMUX sections of the Operator Messages Manual, respectively.

HP provides a comprehensive library of troubleshooting guides for the communications subsystems. Attempt to analyze the problems and restart the process or object using the commands described in the appropriate manual listed in Related Reading on page 6-13.If you are unable to start a required process or object, contact your service provider.

For more information about monitoring and performing recovery operations for communications subsystems, see the manuals listed in Table 6-1. The appropriate manual to use depends on how your system is configured.

For example, if a process is configured using the SCF interface to the WAN subsystem and then reconfigured with the SCF interface to another subsystem, only the SCF interface to the other subsystem would provide current information about the configuration. The SCF interface to the WAN subsystem would provide only information about the configuration before it changed.
