• The FRU history table, which contains logs of insertions and removals of FRUs into and from the
chassis. The content of this table is not audited or verified.
• The IP data table, which contains management module and chassis management IP addresses/
masks, the IP default gateway, and the chassis name.
• A power-off list, which controls the order in which blades are automatically powered off if an
impending power loss is detected.
• A set of Data Center Ethernet (DCE) data containing chassis MAC addresses, without which the
switch will not function.
Automatic auditing and verification of CID card data
The contents of both CID cards are verified on a periodic basis and whenever an event indicates that
an issue may exist.
Under normal circumstances, the CID card audit is run for about one hour after a system startup or
restart, then is repeated every 24 hours. If no errors occur, no action is taken.
If CID card errors occur, if mismatches between data sets on the two CID cards are detected, or if a
card is inserted, RASLogs are shown on the console:
• [EM-1020], … M1, ERROR, … A problem was found on one or both CID cards (x), please run the
cidrecov tool to get more information and recovery options.
• [EM-1021], … M1, INFO, … A CID card has been inserted, a CID verification audit will be run to
detect any mismatches or other problems.
• [EM-1022], … M1, WARNING, … A CID card access problem has been encountered, please run
the cidrecov tool to get more information and recovery options.
Enabling the CID recovery tool
You should run the CID recovery tool when instructed by a RASLog, and you can also run the tool if
you suspect an issue with one or both of the CID cards. To run the CID recovery tool, enter the
cidrecov command in privileged EXEC mode on the command line:
sw0# cidrecov
Managing data corruption or mismatches
If cidrecov detects any CID 1 or CID 2 non-critical SEEPROM corruption or mismatches, the tool
displays related data and the following data-recovery options as applicable for each data-set error:
• Exit. Select this option if you do not want to change any data values.
• Recover with default values. Select this option if you want to reset all data in the data set to the
factory defaults. For IP data, dummy IP addresses and masks are written. DCE and chassis-
configuration data are based on the chassis type.
A system restart repopulates IP addresses and chassis names that appear in the startup configuration
file. If you want to manually change the IP data, you can use the ip-address, chassis virtual-ip, and
chassis-name commands. For more information, refer to the Network OS Command Reference.
