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.
HSG60 Setup
Before the HSG60 RAID Array can be utilized by the Host System, the array must be
properly configured. Use the HSG60 Command Line Interpreter (CLI) to complete the
following tasks.
NOTE: The exact command syntax can be found in the Compaq StorageWorks HSG60 Array
Controller ACS Version 8.6 CLI Reference Guide.
Ensure that the HSG60 controllers have been set correctly for arbitrated loop or fabric.
Compare the settings displayed by the CLI with those in Table 1–2 for arbitrated loop and
Table 1–3 for fabric. The current settings can be obtained with the command:
HSG60>SHOW THIS_CONTROLLER
