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, will reassign 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 will be isolated as a separate fabric and the Logged-In LEDs on both switches
will 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 will be 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 will reassign the domain ID and the
switch will join 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
