Accessing the Core Dump File
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.
