3-4 Sun StorEdge A3500/A3500FC Hardware Configuration Guide • December 1999
FIGURE 3-4 12-Drive StorEdge D1000 SCSI Disk ID (Split Bus)
3.1.1.2 Module ID Switch
Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to
TABLE 3-1.
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.
3.1.1.3 SCSI 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.
