Table 51 Port numbering schemes for the 4/256 SAN Director (continued) Port blades 4/256 SAN Director FA4-18 FR4-18i Fibre Channel ports are numbered from 0 through 15 from bottom to top. There are also 2 GbE ports (numbered A0 - A1, from top to bottom) that are for Storage Application manageability purposes; you cannot address these ports using the CLI. Ports are numbered from 0 through 15 from bottom to top. There are also 2 GbE ports (numbered ge0-ge1, from bottom to top). So going from bottom to top, the 2 physical GbE ports appear on the bottom of the blade followed by 16 physical FC ports. In the 4/256 SAN Director, all the ports are part of a single logical switch. With Fabric OS v4.4.0 and later, you can configure the SAN Director 2/128 as two logical switches (domains). The following sections tell how to identify ports on SAN Director 2/128 and 4/256 SAN Director, and how to identify ports for zoning commands. By slot and port number The port number is a number assigned to an external port to give it a unique identifier in a switch. To select a specific port in the SAN Director 2/128, and 4/256 SAN Director models, you must identify both the slot number and the port number using the format slot number/port number. No spaces are allowed between the slot number, the slash (/), and the port number. The following example shows how to enable port 4 on a blade in slot 2: switch:admin> portenable 2/4 By port area ID The relationship between the port number and area ID depends upon the PID format used in the fabric: • When Core PID format is in effect, the area ID for port 0 is 0, for port 1, it is 1 and so forth. When using Core PID mode on the SAN Director 2/128 configured with two domains, the area IDs for both logical switches (domains) range from 0 to 63. This means that both logical switch 0 and logical switch 1 have a port that is referenced with area ID 0. For 32-port blades in the 4/256 SAN Director (using FC4-32), the numbering is contiguous up to port 15; from port 16, the numbering is still contiguous, but you must add 128 to each port number. For example, port 16 in slot 1 has a port number and area ID of 128; port number 15 has a port number and area ID of 15. For 48-port blades in the 4/256 SAN Director (using FC4-48), the numbering is contiguous up to port 15; from port 16 the numbering is still contiguous, but you must add 128 to each port number. For example, port 48 in slot 1 has a port number and area ID of 176; port number 48 has a port number and area ID of 48. • When Extended-edge PID format is in effect, the area ID is the port number plus 16 for ports 0 to 111. For port numbers higher than 111, the area ID wraps around so that port 112 has an area ID of 0, and so on. Each 64-port logical switch (domain) has area IDs ranging from 16 to 79. Port numbers higher than 128 are mapped directly to the core PID. For details about port area IDs in Extended-edge PID mode, see Changing to extended edge PID format, page 430. • If you perform a port swap operation, the port number and area ID no longer match. To determine the area ID of a particular port, enter the switchShow command. This command displays all ports on the current (logical) switch and their corresponding area IDs. 204 Configuring Directors
