Kernel Core Dumps
Caution Changes to the kernel cores should be made by an administrator or individual who is completely familiar
with switch operations.
When a specific module's operating system (OS) crashes, it is sometimes useful to obtain a full copy of
the memory image (called a kernel core dump) to identify the cause of the crash. When the module
experiences a kernel core dump it triggers the proxy server configured on the supervisor. The supervisor
sends the module's OS kernel core dump to the Cisco MDS 9000 System Debug Server. Similarly, if the
supervisor OS fails, the supervisor sends its OS kernel core dump to the Cisco MDS 9000 System Debug
Server.
The Cisco MDS 9000 System Debug Server is a Cisco application that runs on Linux. It creates a
Note
repository for kernel core dumps. You can download the Cisco MDS 9000 System Debug Server from
the Cisco.com website at http://www.cisco.com/kobayashi/sw-center/sw-stornet.shtml.
Kernel core dumps are only useful to your technical support representative. The kernel core dump file,
which is a large binary file, must be transferred to an external server that resides on the same physical
LAN as the switch. The core dump is subsequently interpreted by technical personnel who have access
to source code and detailed memory maps.
