A core dump file can be very large. Due to memory requirements the file can only be sent directly to an FTP server; it is not stored on the local flash. To enable full kernel core dumps, use the following command. • Enable stack unit kernel full core dumps. CONFIGURATION mode logging coredump server To undo this command, use the no logging coredump server command. Mini Core Dumps Dell Networking OS supports mini core dumps on the application and kernel crashes. The mini core dump applies to Master, Standby, and Member units. Application and kernel mini core dumps are always enabled. The mini core dumps contain the stack space and some other minimal information that you can use to debug a crash. These files are small files and are written into flash until space is exhausted. When the flash is full, the write process is stopped. A mini core dump contains critical information in the event of a crash. Mini core dump files are located in flash:/ (root dir). The application mini core filename format is f10StkUnit..acore.mini.txt. The kernel mini core filename format is f10StkUnit.kcore.mini.txt. The following are sample filenames. When a member or standby unit crashes, the mini core file gets uploaded to master unit. When the master unit crashes, the mini core file is uploaded to new master. The panic string contains key information regarding the crash. Several panic string types exist, and they are displayed in regular English text to enable easier understanding of the crash cause.
