Admin domain compatibility and availability
Admin Domains maintain continuity of service for Fabric OS 5.2.x features and operate in mixed-release
fabric environments. High availability is supported along with some backward compatibility. The following
sections describe the continuity features of Admin Domain usage.
Admin domains and merging
When an E_Port comes online, the adjacent switches merge their AD databases. The receiving switch
accepts an AD database from the neighboring switch only if the local AD database is empty or if the new
AD database exactly matches both the defined and effective configurations of the local AD database. If the
AD database merge fails, the E_Port is segmented with “AD conflict” error code.
Compatibility
Admin Domains can be implemented in fabrics with mix of AD-aware switches and AD-unaware switches.
The following considerations apply:
In mixed-fabric configurations, the legacy switches allow unfiltered access to the fabric and its devices;
hence, these legacy switches should be managed by the physical fabric administrator.
You must zone all ports and devices from legacy switches in the AD0 root zone database.
If you have legacy switches in your AD-activated fabric, you must ensure that all new AD resources have
enough interconnectivity so that they do not get isolated into subfabrics with a legacy subfabric
interposed in the middle, as shown in
Figure 8
.
