Fabric OS 5.2.x administrator guide 393

Performing PID format changes

There are several routine maintenance procedures which might result in a device receiving a new PID. 

Examples include, but are not limited to:

•

Changing compatibility mode settings

•

Changing switch domain IDs

•

Merging fabrics

•

Relocating devices to new ports or new switches (that is, for Add, Move, Change type operations)

•

Updating the core PID format

•

Using hot spare switch ports to deal with failures

In every case where devices employ static PID binding, any such procedure becomes difficult or impossible 

to execute without downtime. 
In some cases, device drivers allow you to specify static PID binding. In these cases, such devices must be 

identified and their PID binding should be changed to WWN binding.
The following sections contain a basic procedure that summarizes the steps necessary to perform PID 

format changes without disrupting the fabric, and special procedures for HP/UX and AIX.

Basic procedure

This process should be executed as part of the overall online or offline update process. However, it can be 

implemented in a stand-alone manner on a non-production fabric, or a switch that has not yet joined a 

fabric.

1.

Ensure that all switches in the fabric are running Fabric OS versions that support the addressing mode. 

It is recommended that you use v2.6.2 for 1 GB switches, v3.1.2 for 2/8EL and 2/16 SAN switches, 

v4.2.0 for HP StorageWorks Core Switch 2/64 and SAN Director 2/128 Directors, as well as SAN 

Switch 2/8V, SAN Switch 2/16V, and SAN Switch 2/32 switches, v5.0.1 for 4/256 SAN Director, 

and 5.1.x for 4/64 SAN Switch, 400 MP Router and B-series MP Router blade require 5.1.0b firmware.

NOTE:

All switches running any version of Fabric OS 4.0.0 and later are shipped with the Core Switch 

PID Format enabled, so it is not necessary to perform the PID format change on these switches.

2.

Telnet into one of the switches in the fabric.

3.

Disable the switch by entering the 

switchDisable

 command. 

4.

Enter the 

configure

 command (the configure prompts display sequentially).

5.

Enter 

y

 after the “Fabric parameters” prompt.

6.

Enter 

1

 at the “Core Switch PID Format” prompt.

7.

Complete the remaining prompts or press 

Ctrl-d

 to accept the remaining settings without completing 

all the prompts.

8.

Repeat steps 2 through 7 for the remaining switches in the fabric.

9.

Re-enable the switch by entering the 

switchEnable

 

command.
