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 establishes the fabric. If you lock the domain ID on a switch and a domain ID
conflict occurs, one of the switches is isolated as a separate fabric and the Logged-In LEDs on both switches
will flash to show the affected ports. See the HP StorageWorks SN6000 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 is 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 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
<tab> 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 <tab> /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 (,).
