Messages That May Indicate Wwn Card - IBM SAN512B-6 Installation, Service And User Manual

v 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 151. If recovery is not possible,
command output will direct you to replace the affected card(s).
v 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 78. Note that the LED patterns may
temporarily change during POST and other diagnostic tests.
v Problems viewing or modifying the data stored on the WWN card.
v Error messages regarding WWN units in chassisshow output.
Error messages that may indicate problems with a WWN card are summarized in
the following table.
