Fabric OS 5.3.0 administrator guide 151
• Move devices from one Admin Domain to another without traffic disruption, cable reconnects, or
discontinuity in zone enforcement.
• Provide strong fault and event isolation between Admin Domains.
• Have visibility of all physical fabric resources. All switches, E_Ports, and FRUs (including blade
information) are visible.
• Implement Admin Domains in a fabric with some switches running AD-unaware firmware versions (that
is, firmware versions lower than Fabric OS 5.2.x).
• Continue to run existing third-party management applications. Prior and existing versions of third party
management applications continue to work with admin and user IDs.
NOTE: The Admin Domain administrator can define up to 255 ADs (AD0 – AD254) in the AD database;
however, Fabric OS supports only 16 active Admin Domains running concurrently. More than 16 active
Admin Domains might cause performance degradation and unpredictable system behavior.
Requirements for admin domains
This section lists the requirements for implementing Admin Domains in a fabric. For information about
supported AD platforms, see the latest version of the
HP StorgeWorks Fabric OS 5.2.x release notes
.
• Admin Domains are supported only on fabrics with one or more switches running Fabric OS 5.2.x and
higher.
• You must have a valid Advanced Zoning license to use Admin Domains.
• The default zone mode setting must be set to No Access before you create Admin Domains (see
” Implementing admin domains ” on page 159).
• To use Admin Domains and the FC-FC Routing Service in the same fabric, the switches connecting to
the FC Router must be running Fabric OS 5.2 or higher.
• If you are using LSAN zones:
• Do not use LSAN zone names ending with “_AD
n
” (where
n
is the Admin Domain number).
• Do not use LSAN zone names longer than 57 characters.
• You must be in the native operating mode to use Admin Domains. Admin Domains are not supported in
interoperability mode.
• Gigabit Ethernet (GbE) ports cannot be members of an Admin Domain.
User-defined Administrative domains
AD1 through AD254 are user-defined Admin Domains. These user-defined Admin Domains can be created
only by a physical fabric administrator (see ” Admin domain access levels ” on page 153 for more
information).
In
Figure 3 , AD1 and AD2 are user-defined Admin Domains.
System-defined administrative domains
When you install Fabric OS 5.2.x or later firmware, the switch enters AD-capable mode with domains AD0
and AD255 automatically created. AD0 and AD255 are special Admin Domains. AD0 and AD255
