Mini Core Dumps Dell Networking OS supports mini core dumps for kernel crashes. The mini core dump applies to Master units. Kernel mini core dumps are always enabled. The mini core dumps contain the stack space and some other very minimal information that can be used 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://CORE_DUMP_DIR directory. The kernel mini core filename in the RPM has the following formats: • Kernel mini core dump generated from CP of the RPMs: f10Ch_rpm_cp_.kcore.mini.txt • Kernel mini cored ump from RP CPU: f10Ch_rpm_rp_.kcore.mini.txt • Kernel mini core dump from LP CPU: f10Ch_lp_.kcore.mini.txt • The Kernel mini core dump generated from the LM: f10Ch_lp_.kcore.mini.txt 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. Example of a Mini Core Text File VALID MAGIC PANIC STRING panic string is :
