FIGURE 3-412-DriveStorEdge D1000 SCSI Disk ID (Split Bus)

3.1.1.2Module ID Switch

Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to TABLE 3-1.

TABLE 3-11x2 Module ID Switch Settings

Disk array number		Module ID setting

2	(Top)	2
1	(Bottom)	1

Note –Since the top and bottom disk arrays are split between one controller module, the Module IDs will overlap. This may result in error messages while the host system is booting. The ASC/ASCQ codes for this error is 98/01, and the Sense Key is 6. These error messages are information only and will not impact system performance.

3.1.1.3SCSI Jumper Cables and Terminators

The StorEdge D1000 disk arrays should have differential SCSI terminators on the inside IN/OUT-1 and IN/OUT-2 SCSI connectors. This configuration is shown in FIGURE 3-11.
