Article ID: KB31197 KB Last Updated: 14 Dec 2016Version: 1.0

This article describes a procedure to collect satellite device core-files required by JTAC to debug or troubleshoot issues reported in Junos Fusion solution.


Verify satellite core files using following command:

root@AD> show system core-dumps satellite 202
215 Data follows, terminated by "."
Slot-ID: 202
ls: cannot access /var/tmp/*exception*: No such file or directory
total 9788

-rw-r--r-- 1 root root 3048619 Sep 7 14:33 sd202.spfe.2479.1473258820.core.tgz
-rw-r--r-- 1 root root 3141512 May 2 14:13 sd202.spfe.25424.1462198422.core.tgz
-rw-r--r-- 1 root root 3054226 Apr 30 21:47 sd202.spfe.2906.1462052874.core.tgz


The following command will copy core files from SD to AD.

AD> request chassis satellite file-copy <source SD> <destination-AD>

<source-SD> URL of source file e.g. For SD, use sd100:/
<destination-AD> URL of destination file e.g. For AD, use /var/tmp/Core_destination

labroot@AD> request chassis satellite file-copy sd202:/var/tmp/corefiles/* /var/tmp/Core_destination
