Admin Domain compatibility, availability, and merging
Admin Domains maintain continuity of service for Fabric OS features and operate in mixed-release
Fabric OS environments. High availability is supported with some backward compatibility.
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 an "AD conflict" error code.
SAN management with Admin Domains
This section is for both users and administrators and describes how Admin Domains affect commands
and other Fabric OS features. If you are a physical fabric administrator and you want to create, modify,
or otherwise manage Admin Domains, refer to Admin Domain management for physical fabric
administrators on page 471.
The Admin Domain looks like a virtual switch or fabric to a user. However, based on the user role and
type (User_ID), users are presented with only their relevant AD-based views (refer to Figure 63 on
page 456 and Figure 64 on page 457). Any devices and switch ports that are not defined as part of the
Admin Domain are not shown and are not available to that AD user.
