power-on self test
(POST) — Series of self-tests executed each time the unit is booted or reset.
preferred domain ID
Domain ID that a director or switch is assigned by the principal switch in a switched fabric. The
preferred domain ID becomes the active domain ID except when configured otherwise by the
user.
principal switch
The director or switch that allocates domain IDs to itself and to all other switches in a fabric.
There is always one principal switch in a fabric. If a switch is not connected to any other
switches, it acts as its own principal switch.
private device
A loop device that cannot transmit a fabric login command (FLOGI) command to a switch or
director, nor communicate with fabric-attached devices. Contrast with
public
device.
private loop
A private arbitrated loop is not connected to a switched fabric. All devices attached to the loop
can only communicate with each other. Contrast with
public
loop.
product name
User-configurable identifier assigned to a managed product. Typically, this name is stored on
the product itself. For the director, the product name can also be accessed by an SNMP manager
as the system name.
Product Status Log
A log recorded at the EFC Manager application that displays an entry when the status of a
director or switch changes. The log reflects the previous status and current status of a managed
product, and indicates the instance of a Element Manager application that should be opened to
investigate a problem.
