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 (ALPA). The maximum number of switches within a fabric is 239
with each switch having a unique domain ID. If you connect a new switch to an
existing fabric and a domain conflict occurs, the new switch will isolate as a
separate fabric. However, you can remedy this by explicitly changing the domain
ID on the new switch.
4.6.2.2
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 <tab> separates the selector field
(local0.info) and action field which contains the log file path name
(/var/adm/messages/messages.name).
local0.info <tab> /var/adm/messages.name
4.6.2.3
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 illegal characters are the pound sign (#), semi-colon (;), and
comma (,).
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.
