Server initialization, recovery, and resets

Link Recovery

Using the bash shell in a telnet session
The bash shell opened during a telnet session is used to access the global platform level in the S8100
system. Once this interface is established:
Use alarmstat command.
1
alarmstat will display all active global, Communication Manager and INTUITY AUDIX
alarms.
If there are any global alarms, use gamalarmstat to see details of global alarms.
2
Use restartcause to obtain information about system restarts. See
3
Commands Reference (555-245-101).
For more information, refer to the manual Installation and Upgrades for the Avaya S8100 Media Server
with the Avaya G600 and CMC1 Media Gateways, 555-233-146.
Obtaining information from Communication Manager alarms
You can use the following Communication Manager commands to obtain more alarm information.
1 Use display alarms command:
Issuing the display alarms command at the administration terminal shows where maintenance
thinks the problem lies. The alarms are a good indication of why the system went down. They
should be used along with the following two methods.
2 Observe red LEDs on the circuit pack to determine where software or processor firmware had a
problem.
3 Use the reset command:
Removing a system from the SPE-Down mode
NOTE:
This is important! If you cannot complete the first step or have problems with the
maintenance interface, then the first step should be to replace the Processor circuit pack.
1 Determine which circuit pack is defective by displaying alarms and observing the red LEDs (as
discussed previously).
