• Providing enclosure status data to the controllers.
• Reporting the WWN and the logical address of all disk drives.
NOTE: Although the EMU can determine the logical address of a drive, the EMU can neither
display nor change this information. HP P6000 Command View can display the addresses from
the EMU-supplied status information.
