1 AD0 is a special Admin Domain that contains all switches, ports, and devices that have not been put into other Admin Domains. AD255, another special domain, is an unfiltered view of the entire physical fabric. Note Some features work only in AD255 when user-defined domains are present, such as ACL management. By default, all fabric elements belong to AD0. In Fabric OS v5.2.0 and higher, a physical fabric administrator with appropriate permissions can create up to 254 additional Admin Domains and assign fabric resources to them (see Chapter 8, "Managing Administrative Domains"). Only users who have been specifically assigned to those domains can view and modify the resources they contain. Admin Domains and Login You are always logged in to an Admin Domain, and you can view and modify only the devices in that Admin Domain. You can log in to only one Admin Domain at a time. When you log in, you select the Admin Domain that you want to manage. You can later change the Admin Domain to which you are logged in. If you have more than one Admin Domain, one of them will have been specified as your "home Admin Domain." Your home Admin Domain is the one you are automatically logged in to unless you explicitly select a different one. If a home Admin Domain is deleted or deactivated, then by default you will be logged in to the lowest numbered Admin Domain in your Admin Domain list. A home Admin Domain, like the Admin Domain list, is a configurable property of a non-default user account. For default accounts such as admin and user, the home Admin Domain defaults to AD0 and cannot be changed. For user-defined accounts, the home Admin Domain also defaults to 0 but an administrator can set the home Admin Domain to any Admin Domain to which the account has been given access. The Admin Domain List for default admin accounts is 0-255, which gives automatic access to any Admin Domain as soon as it is created, and makes them physical fabric administrators. The Admin Domain list for the default user account is AD0 only. The Admin Domain list property for default accounts also cannot be changed. A "physical fabric administrator" is an admin role user whose account has access to all Admin Domains (AD0-255) as soon as they are created. Only physical fabric administrators can create, modify, delete, and activate or deactivate Admin Domains. Admin Domains and Switch WWN 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). The switch WWN is in 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 where xx is the AdminDomain_number.
