Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 665)

• Recover BAD from GOOD. This option is offered only if one CID card contains good data and the
other card contains corrupt data. If you select this option, cidrecov copies the good data onto the
affected card.
• Recover CID 2 from CID 1 and Recover CID 1 from CID 2. These options are offered only if the
data on both CID cards is good but there is a mismatch. You can select which card to use to
overwrite data on the other card.
The following is an example of running the cidrecov tool, receiving errors that can be fixed, and
selecting the Recover BAD from GOOD option (note that the example below contains only some of the
actual output):
sw0# cidrecov

Understanding CID card failure
If the critical SEEPROM of a CID card contains any errors, or if the noncritical SEEPROM cannot be
read, then recovery is not possible and the following message is displayed:
Recovery is not possible. Please contact Brocade Technical Support for replacement of
the inaccessible CID(s).
