Admin Domain management for physical fabric administrators 17 Setting the default zoning mode for Admin Domains To begin implementing an Admin Domain structure within your SAN, you must first set the default zoning mode to No Access. You must be in AD0 to change the default zoning mode. 1. Log in to the switch with the appropriate RBAC role. 2. Ensure you are in the AD0 context by entering the ad --show command to determine the current Admin Domain. If necessary, switch to the AD0 context by entering the ad --select 0 command. 3. Set the default zoning mode to No Access, as described in "Setting the default zoning mode" on page 326. Creating an Admin Domain To create an Admin Domain, you must specify an Admin Domain name, number, or both: • If you create an Admin Domain using only a number, the Admin Domain name is automatically assigned to be "ADn", where n is the number you specified. For example, if you specify AD number = 4, then AD name is set to "AD4". • If you create an Admin Domain using only a name, the Admin Domain number is automatically assigned and is the lowest available AD number, except if you specify a name in the format "ADn", in which case the Admin Domain number is assigned to be n. For example, if you specify AD name = "blueAD" and the lowest available AD number is 5, then AD name is "blueAD" and AD number is 5. If you specify AD name = "AD15" and the lowest available AD number is 6, then AD name is "AD15" and AD number is 15. Because the specified name is in the format "ADn", the AD number is assigned to be n and not the lowest available AD number. When you create an Admin Domain, you must specify at least one member (switch, switch port, or device). You cannot create an empty Admin Domain. For more information about these member types, refer to "Admin Domain member types" on page 439. A newly created Admin Domain has no zoning defined and the default access mode is No Access. This means the devices in the Admin Domain cannot communicate with each other. You must set up zones in the newly created Admin Domain to allow devices to access each other, even if the devices were already zoned together prior to your moving them to the Admin Domain. Refer to "Admin Domains, zones, and zone databases" on page 458 for additional information about how zones work with Admin Domains. You create Admin Domains in the transaction buffer. You can either save the newly created Admin Domain to a defined configuration or make it the effective configuration directly. The following procedure describes the steps for creating Admin Domains. 1. Log in to the switch as the physical fabric administrator. 2. Disable Virtual Fabrics, if necessary, as described in "Disabling Virtual Fabrics mode" on page 290. Admin Domains and Virtual Fabrics cannot co-exist. 3. Set the default zone mode to No Access, if you have not already done so. Refer to "Setting the default zoning mode" on page 326 for instructions. 4. Switch to the AD255 context, if you are not already in that context: Fabric OS Administrator's Guide 443 53-1002745-02
