SAN Switch 2/16 Version 3.1.x Installation Guide
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:
If you are in the process of creating a new SAN, set the PID format to 1, if
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.
1. Type
configShow
and press Enter.
2. About 15 lines down (press Enter to display more information on the page),
locate the following line:
fabric.ops.mode.pidFormat: [1 or 0]
Note:
In the above example, the Core PID format is 1 or 0, depending on the number
displayed in the brackets.
