Administrative Domains overview

Switch members
Switch members are defined by the switch WWN or domain ID, and have the following properties:
• A switch member grants administrative control to the switch.
• A switch member grants port control for all ports in that switch.
• A switch member allows switch administrative operations such as disabling and enabling a
switch, rebooting, and firmware downloads.
• A switch member does not provide zoning rights for the switch ports or devices.
To allow devices to be zoned within Admin Domains, you must specify the port members using
domain,index or device WWN members.
E_Ports (including VE_Ports, EX_Ports, and VEX_Ports) are implicitly shared across all Admin
Domains. An administrator can perform port control operations only if the domain,index of the
E_Port is part of the Admin Domain.
NOTE
Only the WWN of the switch is saved in the Admin Domain. If you change the domain ID of the switch,
the Admin Domain ownership of the switch is not changed.
Admin Domains and switch WWNs
Admin Domains are treated as fabrics. Because switches cannot belong to more than one fabric,
switch WWNs are converted so that they appear as unique entities in different Admin Domains
(fabrics). This WWN conversion is done only in the AD1 through AD254 context. AD0 and AD255
use unconverted switch WWNs.
The switch WWN has the following format:
10:00:nn:nn:nn:nn:nn:nn
In an Admin Domain context, the switch WWN is converted from NAA=1 to NAA=5 format, with the
Admin Domain number added, using the following syntax:
5n:nn:nn:nn:nn:nn:n9:xx
In the syntax, xx is the Admin Domain number.
For example, the following switch WWN is in NAA=1 format:
10:00:00:60:69:e4:24:e0
The following switch WWN is the converted WWN for the previous example in AD1:
50:06:06:9e:42:4e:09:01
Figure 59 on page 347 shows an unfiltered view of a fabric with two switches, three devices, and
two Admin Domains. The devices are labeled with device WWNs and the switches are labeled with
domain IDs and switch WWNs.
