Configuring Device Alias Modes - Cisco Nexus 5500 Series NX-OS Configuration Manual

Distributing Device Alias Services
• If you remove a device alias from the device alias database, all applications automatically stop enforcing
the corresponding device alias. If that corresponding device alias is part of an active zone set, all the
traffic to and from that pWWN is disrupted.
• Renaming the device alias not only changes the device alias name in the device alias database, but also
replaces the corresponding device alias configuration in all of the applications.
• When a new device alias is added to the device alias database, and the application configuration is present
on that device alias, it automatically takes effect. For example, if the corresponding device alias is part
of the active zoneset and the device is online, then zoning is enforced automatically. You do not have
to reactivate the zone set.
• If a device alias name is mapped to a new HBA's pWWN, the application's enforcement changes
accordingly. In this case, the zone server automatically enforces zoning based on the new HBA's pWWN.
