4. The switch may have had diffic ulty in writing to the hard patc h file. Check
the hardware error log for proces sor/memory board failures.
5. The hard patch file may be full. Issue a reset system 1. This should cause
valid files to be applied and invalid ones to be erased.
Error on Application of the Patch
A patch may not have been applied for the following reasons:
1. The memory card is write-protecte d. Remove this protection and issue a
reset system x command
2. The patch identifiers are inco nsistent. Run list configuration software
and compare the old _patch identifier with the values in the up date file.
3. The LMM encountered a problem with t he patch file. This is unlikely
because the same chec ks (and more) were performed when the file was
downloaded, p rior to marking the file valid. This impl ies that the memory
that stored the update file was c orrupted.
a. Apply the bac k out file immediately to bac k out the changes.
b. Run the flash checksum test to make sure the system is back to its
prepatch state.
c. Check the validity of t he file again
d. Try redownloading and applying the patch immediately.
4. The LMM reports a hard error. Symptoms of this are an entry in the
hardware error log for the proc essor/memory board (if you’re luc ky), or
extremely odd switch b ehavior followed by SPE down mode (if you’re not).
The problem is that the LMM cannot c omplete the programming of
memory with the result that memory is in a corrup ted state. The only
recovery is to get or order new softw are and processor/ memory c ircuit
packs.
Good application - bad patch
This error is not caused by a failure in the download or application, b ut by a fault
in the patch file itself. To recover from this type of prob lem, the back out file that
backs out the patc h should be down loaded and ap plied. This requires that the
system be sane enough to recei ve the file correctly and b e able to apply i t.
