If a module fails and saves a core dump file to NVS memory (which can take several
minutes), and you have not configured the Core Dump Monitor for automatic transfer,
you must transfer the file to a network host before it can be examined. You can transfer
the core dump file when the module is back online or has assumed a redundant status.
For information about the status of modules, see ERX Hardware Guide, Chapter 9,
Troubleshooting. To transfer the core dump file to a network host, use the copy command.
In a system with two SRP modules, the following behavior applies if you have configured
the SRP modules to save core dump files to an FTP server:
If the primary SRP module fails, it saves the core dump file to the FTP server before
the standby SRP module assumes control.
If the standby SRP module fails, it must save the core dump file to NVS because it has
no access to any configured network host.
The show version command output indicates the failed SRP module state as not
responding during the save process. Consequently, when the failed SRP module recovers
and assumes the role of redundant module, the show version command output indicates
the SRP module state as standby and displays output for the standby SRP. The standby
SRP can notify the primary SRP during a core dump. Output from the show version
command displays core dumping for the Standby SRP.
If the standby SRP boot image encounters a problem loading the diagnostics or
operational image, the state of the standby SRP appears as disabled (image error). When
standby SRP diagnostics encounter a test failure, the primary SRP is notified and the
state is set to hardware error.
You can now transfer the core dump file to a network host for examination. For example,
to transfer the file SRP_1_SC_05_24_2000_02_20.dmp from NVS of the failed SRP module
to the host server1, enter the following command:
host1#copy SRP_1_SC_05_24_2000_02_20.dmp
host:/public/server1/SRP-5G_1_SC_05_24_2000_02_20.dmp
