set it to NONE, which tells the X24 Subsystem not to present a LUN for this EMP under the X24
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
X24 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 X24 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 SAM, select Manage X24 Subsystem > General Config > Enclosure Management .
The Enclosure Management page displays. The Set X24 EMP LUNs panels display the current LUN for
each EMP. Each EMP has an EMP number that the X24 Subsystem assigns sequentially whenever it
starts.
2 Select the LUN you want for each EMP.
3 Click Update EMP Configuration .
6.2.2 Changing the Additional EMP Setting
You can change four additional EMP settings:
• EMP Polling Rate : This is the interval, in seconds, that the X24 Subsystem polls the EMPs for status
changes. If the polling rate is set to zero, the X24 Subsystem does not communicate with the EMP.
Only use this setting if you suspect you are having communication problems with the EMP. The
default setting is five seconds.
To change the EMP setting:
1 From SAM, select Manage X24 Subsystem > General Config > Enclosure Management .
The Enclosure Management page displays.
2 In the Enclosure Management Processor General Settings panel, select EMP Polling Rate .
3 Click Update EMP Configuration
