Troubleshooting guide
5. Obtaining Failure Information
179
1. In the active system, execute the dump psp command for the PSP in the active system.
2. In the active system, execute the
dump nif command for the port that has failed.
Example:
The following procedure shows an example in which communication fails on port number 1
of NIF number 1.
1. Log in to the active system, and then execute the
dump command.
> dump psp
Dump command accept.
>
11/01 17:43:42 E3 CSU 25070700 2301:000000000000 PSP online dump command
executed.
2. After the above log information is displayed, execute the following dump command.
> dump nif 1
Dump command accept.
>
11/01 18:10:42 E3 NIF NIF:1 25000700 1240:000000000000 NIF online dump
command executed.
In the AX6300S series:
1. In the active system, execute the dump psp command for the PSP in the active system.
2. In the active system, execute the
dump nif command for the port that has failed.
Example:
The following procedure shows an example in which communication fails on port number 1
of NIF number 1.
1. Log in to the active system, and then execute the
dump command.
> dump psp
Dump command accept.
>
11/01 17:43:42 E3 MSU 25070700 2301:000000000000 PSP online dump command
executed.
2. After the above log information is displayed, execute the following dump command.
> dump nif 1
Dump command accept.
>
11/01 18:10:42 E3 NIF NIF:1 25000700 1240:000000000000 NIF online dump
command executed.
(2) Capturing a memory dump when a communication failure occurs after a switchover of
the BCU, CSU, or MSU systems
When a communication failure occurs after a system switchover, execute all of the following
commands to capture memory dumps. The captured memory dump files are stored in
/usr/var/
hardware
(for versions prior to Version 10.5, in /dump0) in the system in which the commands
were executed. You need to delete the memory dump files after capturing the memory dumps.
In the AX6700S series:
1. In the active BCU, execute the dump bsu command for all the BSUs that are installed.
2. In the active BCU, execute the
dump nif command for all the ports that have failed.
3. In the standby BCU, execute the
dump bsu command for one of the BSUs that are
installed. You do not have to do this for all the BSUs.
Example:
The following procedure shows an example in which communication fails on port number 1
