Troubleshooting the SWAN Concentrator and WAN Subsystem

Finding SWAN Concentrator and WAN

Subsystem Event Messages in the Event Log

Tip: Before you search the event log ($ZLOG) for SWAN concentrator and WAN

subsystem event messages, you should be familiar with the names of the processes and

objects that support the SWAN concentrator and WAN subsystem devices (DEVICE

object). For information about how to identify these processes and objects, see Identifying

the WAN Subsystem Processes and Objects.

When you view events using the OSM or TSM Event Viewer, the subsystem name (or, in

rare cases, the subsystem number) is shown in the SSID column. The SSID column

identifies the owner-name, subsystem-name, and version. For example:

TANDEM.SLSA.G07

The event viewers allow you to specify the date and time ranges of the events you want

displayed, the logs (such as $0 and $ZLOG) from which you want events displayed, and

the subsystems from which you want events displayed.

Cause, effect, and recovery information for event messages is provided in the Operator

Messages Manual.

Look for messages generated by the subsystems listed in the following table:
