HP StorageWorks SAN Director 2/128 and 4/256 SAN Director: Enter the following command: switch:admin> portdisable slotnumber/portnumber where slotnumber and portnumber are the slot and port numbers of the port you want to disable. How to enable a port 1. Connect to the switch and log in as admin. 2. HP StorageWorks 4/16 SAN Switch and 4/8 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, SAN Switch 4/32, 4/64 SAN Switch, and 400 MP Router: Enter the following command: switch:admin> portenable portnumber where portnumber is the port number of the port you want to enable. HP StorageWorks SAN Director 2/128 and 4/256 SAN Director: Enter the following command: switch:admin> portenable slotnumber/portnumber where slotnumber and portnumber are the slot and port numbers of the port you want to enable. (Slots are numbered 1 through 4 and 7 through 10, counting from left to right.) If the port is connected to another switch, the fabric might reconfigure. If the port is connected to one or more devices, these devices become available to the fabric. If you change port configurations during a switch failover, the ports might become disabled. To bring the ports online, reissue the portEnable command after the failover is complete. Making basic connections You can make basic connections to devices and to other switches. Before connecting a switch to a fabric that contains switches running different firmware versions, you must first set the same PID format on all switches. The presence of different PID formats in a fabric causes fabric segmentation. For information on PID formats and related procedures, refer to "Selecting a PID format" on page 383. For information on configuring the routing of connections, refer to"Routing traffic" on page 221. For information on configuring extended interswitch connections, refer to"Administering Extended Fabrics" on page 341. Connecting to devices To minimize port logins, power off all devices before connecting them to the switch. For devices that cannot be powered off, first use the portDisable command to disable the port on the switch, and then connect the device. When powering the devices back on, wait for each device to complete the fabric login before powering on the next one. Connecting to other switches Refer to the your switch installation guide for interswitch link (ISL) connection and cable management information. The standard (default) ISL mode is L0, which you can configure with the portCfgLongDistance command. ISL Mode L0 is a static mode, with the following maximum ISL distances: • 10 km at 1 Gbit/second • 5 km at 2 Gbit/second • 2.5 km at 4 Gbit/second Fabric OS 5.2.x administrator guide 45
