Restoring

When you restore system NV data, the software presents you with a

NV Data

proposal for how to restore the data. This proposal is based on the

 

restoration rules described here:

 

Rule 1 Exact Match — An exact match is one where the system IDs, module types,

 

and module revisions (if applicable) all match between the saved

 

configuration and the system on which you are restoring the image.

Rule 2 System ID Mismatch — System IDs do not match between the saved NV file and the target system. Mismatches in system IDs are allowed. Before restoring the NV data to a system with a different system ID, you should be aware of the following NV data that might cause problems when restored:

Management IP addresses (defined in IP interface configurations) are saved as NV data and restored. Before connecting the restored system to the network, you might need to change the IP address of defined interfaces to avoid duplicate IP address problems. Modifying IP interface definitions is described on page 3-6.

Statically configured Ethernet addresses are saved as NV data. You must be sure not to have duplicate addresses when you restore the NV data. Listing statically configured addresses is described on page 11-11.

If none of these rules succeeds, you cannot apply the saved configuration to the system.
