(4)Settings of switches
a)Setting of AL-PA switch on disk enclosure
Set an AL-PA by using the AL-PA switch on each adapter of the additional disk enclosure.
The AL-PA switches on both adapters are factory-set to "1". Set an AL-PA so that it will be different from the AL-PAs of other disk enclosures in the same FC loop.
Set "0" for the AL-PA switches on both adapters in the first disk enclosure that is connected to the array controller via the FC cable (HSSDC). If you have installed additional disk enclosures, set the AL-PA switches on both adapters of each additional disk enclosure to "1", "2", ... "5", and then "6" in the connection order.
If you set different values for the AL-PA switches on the right and left adapters of an additional disk enclosure, the FAULT LED on each adapter flashes and the disk enclosure fails to start. If you have set different values, turn off the system including the additional disk enclosure, set the same value for the AL-PA switches, and then turn on the power.
b)Setting of DE-DIAG ID switch on disk enclosure
Set a DE-DIAG ID by using the DE-DIAG ID switch on each adapter of the additional disk enclosure.
Set "0" for all the DE-DIAG IDs of the adapters installed in the disk enclosure that is connected with the standard controller in the array controller via the FC cable (HSSDC).
If an additional control card (NF2300-SP02E) is installed in the array controller, set "1" for all the DE-DIAG IDs of the adapters installed in the disk enclosure that is connected with the additional control card via the FC cable (HSSDC).
The DE-DIAG ID switch is factory-set to "0".
When DE-DIAG ID = "0" When DE-DIAG ID = "1"
The set value of each switch on a disk enclosure is shown in pages 23 and 24.
The disk array unit cannot use the disk enclosure only if the disk enclosure is installed additionally. Provide the proper setting for the disk enclosure by using the "NEC Storage Manager" or contact the service engineer with the expert knowledge.
