• Right-click a switch graphic in the faceplate display, and then select Switch Properties from the popup menu. Figure 27 Switch Properties dialog box Domain ID and Domain ID Lock The domain ID is a unique Fibre Channel identifier for the switch. The Fibre Channel address consists of the domain ID, port ID, and the Arbitrated Loop Physical Address (AL_PA). Switches come from the factory with the domain IDs unlocked. This means that if there is a domain ID conflict in the fabric, the switch with the highest principal priority, or the principal switch, reassigns any domain ID conflicts and establish the fabric. If you lock the domain ID on a switch and a domain ID conflict occurs, one of the switches become isolated as a separate fabric and the Logged-In LEDs on both switches flash to show the affected ports. See the HP StorageWorks 8/20q Fibre Channel Switch Command Line Interface Guide for information about the Domain ID Lock and Principal Priority parameters. If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain conflict occurs, the new switch becomes isolated as a separate fabric. However, you can remedy this by resetting the new switch or taking it offline then back online. The principal switch reassigns the domain ID and the switch joins the fabric. NOTE: Domain ID reassignment is not reflected in zoning that is defined by domain ID and port number pair. You must reconfigure zones that are affected by domain ID reassignment. Syslog The Syslog (Remote Logging) feature enables saving of the log information to a remote host that supports the syslog protocol. When enabled, the log entries are sent to the syslog host at the IP address that you specify in the Logging Host IP Address field. Log entries are saved in the internal switch log whether this feature is enabled or not. To save log information to a remote host, you must edit the syslog.conf file (located on the remote host) and then restart the syslog daemon. Consult your operating system documentation for information on how to configure Remote Logging. The syslog.conf file on the remote host must contain an entry that specifies the name of the log file in which to save error messages. Add the following line to the syslog.conf file. A separates the selector field (local0.info) and action field which contains the log file path name in the format /var/adm/messages/messages.name: local0.info /var/adm/messages.name Symbolic name The symbolic name is a user-defined name of up to 32 characters that identifies the switch. The symbolic name is used in the displays and data windows to help identify switches. The following characters may not be used in the symbolic name: pound sign (#), semi-colon (;), and comma (,).
