Symbolic name
The symbolic name is a user-defined name that identifies the switch module.
Switch module administrative state
The switch module administrative state determines the operational state of the switch and its ports. The switch
module administrative state exists in two forms: the configured administrative state and the current
administrative state. The configured administrative state is the state that is saved in the switch configuration
and is preserved across switch resets. The SAN Utility always makes changes to the configured administrative
state. The current administrative state is the state that is applied to the switch module for temporary purposes
and is not retained across switch resets. The current administrative state is set using the Set Switch command.
For more information about the Set Switch command, see “Set command” on page 24.
Domain ID and Domain ID Lock
The domain ID is a unique Fibre Channel identifier for the switch module. The Fibre Channel address consists
of the domain ID, port ID, and the Arbitrated Loop Physical Address (ALPA). The maximum number of
switch modules within a fabric is 239, with each switch having a unique domain ID.
Switch modules come from the factory with the domain IDs unlocked. This means that if there is a domain ID
conflict in the fabric, the switch module 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 module and a
domain ID conflict occurs, the switch module with the higher WWN will be isolated as a separate fabric, and
the Logged-in LEDs on both switch modules will flash to show the affected ports. See “Set Config command”
