Full core dumps
RP core dumps are enabled by default. CP core dumps are disabled by default. The core dump file is sent
by FTP to the internal flash in the CORE_DUMP_DIR directory once the crashed RPM is back up. Enable
full RPM application and kernel core dumps
with the following:
Undo this command using the no logging coredump [cp|rps|server].
By default the core dump is sent to the internal flash CP and the CORE_DUMP_DIR directory for RP.
However, you can also write the RP core dump file directly to an FTP server the
keyword
server. CP core dumps cannot be sent directly to an FTP server.
The full RPM kernel core dumps for CP and for RP1/RP2 are located in the CORE_DUMP_DIR directory
with the name
f10{cp|rp{1|2}}.kcore.gz.
The full RPM application core dumps for CP and for RP1/RP2 are located in the CORE_DUMP_DIR
directory with the name
f10{cp|rp{1|2}}<yymmddhhmmss>.acore.gz.
If a raw partition is present, the kernel and application core dump files can be deleted if the flash is full.
However, if the raw partition is not present, manually generated will be deleted on the Standby RPM, but
the space is not released. The CP kernel core dump file space cannot be recovered by deleting the files.
You must format the flash drive to recover the space.
The FTOS High Availability module is aware of the core dump upload, and it does not reboot the crashed
RPM until the core dump has completed or is aborted.
Mini core dumps
The RPM mini application and kernel core dumps are always enabled. A mini core dump contains critical
information in the case that a full core dump is not successful, as shown in Figure 63-18. After RPM reset,
the mini core FTP-to-RPM flash process takes about 5 seconds. New files are written in flash until space is
exhausted, in which case the write is aborted. Mini RPM core dump files are located in the
CORE_DUMP_DIR directory with the name
f10cp.kcore.mini.txt (for the kernel) and f10cp.acore.mini.txt
(for the application).
Task Command Syntax Command Mode
Enable RPM core dumps and specify the
shutdown mode.

CONFIGURATION
Note: The core dump file can be large and may take up to 5 to 30 minutes to upload. FTOS does not
overwrite application core dumps, so you should delete them as necessary to conserve space on the flash;
if the flash is out of memory, the core dump is aborted.
