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