Capturing And Writing Core Dumps - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

JUNOSe 11.1.x System Basics Configuration Guide
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:
copy

Capturing and Writing Core Dumps

You can capture and write a core dump to a file for an active or a standby SRP module
or the line modules. You can store the file on the file system or on a network host.
The SRP core dump files are stored on the respective SRP flash memory. The line
module core dump files are stored on the active SRP flash memory at the instance
of the core dump event. The core dump files are not synchronized between the active
and the standby SRP module. You can use the resulting information to help diagnose
a problem or to verify whether the core settings are correct (primarily for the network
settings).
write core
NOTE: The force keyword enables you to specify a slot only if that slot is an SRP
module slot.

host1#copy SRP_1_SC_05_24_2000_02_20.dmp

Use to copy a core dump file.
You cannot use wildcards.
You can copy core dump files only to network locations.
You cannot create or copy over files generated by the system; however, you can
copy such files to an unreserved filename.
Example
host1#copy fault.dmp host:/public/server1/fault.dmp
There is no no version.
See copy.
Use to reboot the active SRP module, the standby SRP module, or the module
in a specified slot, and write the core dump to a file.
If you specify the force keyword, you are prompted for confirmation to reboot
when the router is in a state that can lead to loss of configuration data or NVS
corruption.
