CAUTION: Each subsystem has its own unique worldwide name (node ID). If you
attempt to set the subsystem worldwide name to a name other than the one that came
with the subsystem, the data on the subsystem will not be accessible. Never set two
subsystems to the same worldwide name, or data corruption will occur.
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.
