To disable automatic CompactFlash CRC checksum testing, use the no system health module
cf-crc-check command in EXEC mode.
switch(config)# no system health module number cf-crc-check

Setting the CompactFlash CRC Checksum Test Interval

To set the CompactFlash CRC checksum test interval, use the system health module cf-crc-check
frequency command in configuration mode.
To set the CompactFlash CRC checksum test interval, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# system health module number
cf-crc-check frequency number
switch(config)#
Enabling and Disabling Failure Action at the Failure of a CompactFlash
Checksum Test
You can use the system health module cf-crc-check failure-action command to prevent the Cisco
SAN-OS software from taking any action if a CompactFlash failure is determined while running the
CRC checksum test and the failed CompactFlash is isolated from further testing. By default, this feature
is enabled in all switches in the Cisco MDS 9000 Family. A failure action is controlled at the module
level.
Use the system health module cf-crc-check failure-action command in configuration mode to enable
the CompactFlash CRC checksum test failure action for a module.
To enable the CompactFlash CRC checksum test failure action, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# system health module number
cf-crc-check failure-action
switch(config)#
To disable the CompactFlash CRC checksum test failure action, use the no system health module
cf-crc-check failure-action command in configuration mode.

Displaying the Frequency and Status of the CompactFlash CRC Checksum Test

To display the frequency and status of the CompactFlash CRC checksum test for a specific module, use
the show system health module command in EXEC mode.
switch# show system health module 5
Current health information for module 5.
