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.
