Planning a Subsystem 1–27

■ Controller B, port 1—worldwide name + 1, for example 5000-1FE1-FF0C-EE01

■ Controller B, port 2—worldwide name + 2, for example 5000-1FE1-FF0C-EE02

■ Controller A, port 1—worldwide name + 3, for example 5000-1FE1-FF0C-EE03

■ Controller A, port 2—worldwide name + 4, for example 5000-1FE1-FF0C-EE04

Use the CLI command, SHOW this_controller/other_controller to display the subsystem’s

worldwide name.

Restoring Worldwide Names (Node IDs)

If a situation occurs that requires you to restore the worldwide name, you can restore it

using the worldwide name and checksum printed on the sticker on the frame into which

the controller is inserted.

Figure 1–13 shows the placement of the worldwide name label for the Model 2100

enclosure.

Unit Worldwide Names (LUN IDs)

In addition, each unit has its own worldwide name, or LUN ID. This is a unique, 128-bit

value that the controller assigns at the time of unit initialization. It cannot be altered by the

user but does change when the unit is reinitialized. Use the SHOW command to list the

LUN ID.
