F.2.1 Setting the EMP LUN
If you have only one EMP, the configuration settings are automatically enabled when the Galaxy 65
Subsystem is installed.
If you have more than one EMP, you must set up the EMP LUNs as described in this section.
The Galaxy 65 Subsystem allows in-band access to the EMP in the disk enclosure under the Galaxy 65
Subsystem’s target ID using direct EMP commands. You can set an EMP LUN to any value between 0
and 63, except where it would conflict with a previously assigned LUN (EMP, array, or CAPI [Galaxy 65]).
You can also set it to NONE, which tells the Galaxy 65 Subsystem not to present a LUN for this EMP
under the Galaxy 65 Subsystem’s target ID.
You can set LUNs for EMPs that you plan to add by assigning a LUN to the EMP ID you want to use. The
Galaxy 65 Subsystem assigns EMP IDs sequentially each time it starts.
Note
EMP LUN settings have no effect on the CAPI interface, which always allows communication with all of
the EMPs connected to the Galaxy 65 Subsystem.
You may want to change the EMP LUN if it conflicts with the LUN of another device.
To change the EMP LUN:
1 From the System Menu, select Configuration Menu and press Enter.
The Configuration Menu displays.
2 Select EMP Configuration and press Enter.
The EMP Configuration screen displays.
