Determining the status of a CID card
Each CID card has two serial EEPROMS (seeproms). One is the critical seeprom and the other is the
non-critical seeprom. Problems with the critical seeprom cannot be fixed with the CID Recovery
Tool. Only issues with the non-critical seeprom can be addressed.
Regular validation tests are run by the system comparing the CID cards to each other. If the
information is identical, then the chassis is operating correctly. Once a mismatch is detected, an
FFDC message is output to the RASlog. Refer to
for possible messages.
