NOTE: If the switch domain ID changes, the domain,index members are invalid (they are not automatically changed). You must then reconfigure the Admin Domain with the current domain,index members. Switch members Switch members are defined by the switch WWN or domain ID, and have the following properties: • Grants administrative control to the switch • Grants port control for all ports in that switch • Allows switch administrative operations such as disabling and enabling a switch, rebooting, and firmware downloads • 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 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). This WWN conversion is performed 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 where xx is the Admin Domain number. For example, if the switch WWN is: 10:00:00:60:69:e4:24:e0 then the converted WWN for that switch in AD1 would be: 50:06:06:9e:42:4e:09:01 Figure 23 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 ID and switch WWNs. Fabric OS 6.2 administrator guide 197
