na_memerr - print memory errors
memerr
memerr -v
memerr -h
memerr prints the history of memory (appliance's RAM)
errors since boot. This can be useful in diagnosing memory
problems or determining which DIMM, if any, might need
replacement. Some correctable ECC errors are to be
expected under normal operation, but many more occurring
on a particular DIMM may indicate a problem.
The printout includes correctable, 1 bit ECC memory errors
(CECC errors). It shows the number of these errors per
DIMM. If applicable, it prints a message indicating multiple
errors have occurred at the same physical address in
memory. When this happens, we recommend that the user
replace the affected DIMM because it is more likely to
generate uncorrectable errors.
If the v option is given, a record of the most recent
errors is printed, including the physical slot of the
DIMM, the physical address, and the time. If this error
history is full, a message indicating this will be
printed. This does not mean the error counts per DIMM are
affected.
If correctable ECC errors are not being reported by ONTAP,
it will print a message indicating this. ONTAP only turns
off reporting of CECC errors when they occur at very high
frequency.
-
-v
- Prints individual correctable ECC error records.
-
-h
- Prints the usage.
