Important Information on Setting the Core PID Format

The switch you have purchased may require a change to the configuration setting
known as the Core PID format.
A Core PID format is one of two addressing mechanisms used in Fibre Channel.
The Core PID format is analogous to specifying the physical switch and port a
device is attached to in data networks. It is not analogous to an IP address. PID
formats are assigned by a Fibre Channel switch when a device logs into the fabric.
An example Core PID might look like this:
011F00
In new installations, where both edge and the Core Switch 2/64 reside, you must
verify that the edge switch (for example, SAN Switch 2/16) Core PID format
matches the Core switch's PID format (always 1), before connecting to the SAN.
If a switch is introduced to an existing SAN with a Core PID format setting that
differs from the Core PID format setting in the SAN, the switch will segment.
Note:
possible.

How to Check the Current Core PID Format

To determine a switch's current Core PID format, connect directly to a switch in
your SAN and complete the following steps via a telnet session, or the Serial cable
supplied with the switch.
