Running Compact Flash Tests
As of Cisco SAN-OS Release 3.1(3) and NX-OS Release 4.1(1a), you can run the CompactFlash CRC
checksum test to identify if the CompactFlash firmware is corrupted and needs to be updated. By default,
the CompactFlash CRC checksum test is enabled to automatically run in the background every seven
days (you can change the automatic test interval by using the system health module cf-crc-check
frequency command in configuration mode). You can run the test on demand by using the system health
cf-crc-check module CLI command in EXEC mode. To turn the automatic testing off, use the no system
health module cf-crc-check command in configuration mode.
The CompactFlash CRC checksum test can check if CompactFlash is corrupted on the following
modules:

Running the CompactFlash CRC Checksum Test On Demand

To run the CompactFlash CRC checksum test, use the system health cf-crc-check module command in
EXEC mode.
switch# system health cf-crc-check module number
Where number indicates the slot in which the identified module resides. For example:
switch(config)# system health cf-crc-check module 4

Enabling and Disabling the Automatic CompactFlash CRC Checksum Test

By default, the CompactFlash CRC checksum test is enabled to automatically run in the background.
You can disable the automatic testing and then enable the testing at a later time. You can run the test on
demand at any time by using the system health cf-crc-check module command in EXEC mode.
To enable automatic CompactFlash CRC checksum testing, use the system health module cf-crc-check
command in configuration mode.
switch# system health module number cf-crc-check
Where number indicates the slot in which the identified module resides. For example:
