Domain ID Conflicts

A Domain ID conflict can occur if a switch that is in the online state is added to a
fabric and the joining switch Domain ID conflicts with the Domain ID of a switch
in the fabric. Normally, Domain IDs are automatically assigned; however, once a
switch is online, the Domain ID cannot change, as it would change the port
addressing and potentially disrupt critical I/O.

Restore a Segmented Fabric

The following procedure describes how to check for inconsistent fabric
parameters that cause segmentation. For information on zoning configuration
incompatibility, see “
