WWN card fault indicators
Before replacing a WWN card, verify that the replacement is necessary. Any of the following events can indicate that cards require
replacement:
• RASlog messages may occur during periodic WWN card audit routines alerting you of data or license mismatches between
WWN cards and other errors. Some of these messages may direct you to contact technical support or to run the
wwnrecover
command. You can use this command to further verify or to fix problems. If an EM-1220 or EM-1222 error message occurs
due to WWN card data corruption or data mis-matches across WWN cards, data recovery may be possible using this
command. For more information on using
wwnrecover , refer to Using the wwnrecover utility on page 171. If recovery is not
possible, command output will direct you to replace the affected card(s).
• Status LEDs on the WWN bezel do not reflect the actual status of the WWN cards or indicate a problem. For information on
interpreting LED patterns, refer to
Interpreting WWN card LEDs on page 109. Note that the LED patterns may temporarily
change during POST and other diagnostic tests.
• Problems viewing or modifying the data stored on the WWN card.
• Error messages regarding WWN units in chassisshow output.
Error messages that may indicate problems with a WWN card are summarized in the following table.
