MWAM System Error Messages
Error messages may be received and reported in the system log (SysLog). This section lists these
messages from the MWAM SysLog Files.
Processor Complex Resetting
When upgrading MWAM software, you may see an error message similar to the following:
%SVCLC-SP-5-STRRECVD: mod 5: MWAM: No response from IOS complex <complex>, resetting
complex.
If this occurs, you must upgrade the ROMMON image (see the “Upgrading the ROMMON Image”
section on page 5-11.
Note After receiving the error message, proceed immediately to the procedure named Upgrading the
ROMMON Image, page 5-11 before the error occurs again. If you are unable to perform this procedure
immediately, the processor complex continues to reset at three minute intervals until the ROMMON
image upgrade process is completed. The ROMMON image upgrade process should take approximately
30 seconds to complete.
Crashinfo/Crashdump
Error Message %MWAM_FILESYSTEM-3-FC_CANNOT_FORMAT: Insufficient memory to format
bootflash file system.
Explanation
The router does not have enough working storage available in heap memory to format a
file system for crashinfo data. The router will function normally without a bootflash file system,
however, the router cannot save information for problem analysis if it crashes.
Recommended Action Try to format the file system again at a later time or shortly after a re-boot.
Error Message %MWAM_FILESYSTEM-3-FC_FLASH_WRITE_ERROR: Cannot write to bootflash
file system:
Explanation
The router cannot write to the bootflash.
Recommended Action If the problem occurred while executing a CLI command, try the command
again. If problems persist, contact Cisco technical support.
