Note In split bus mode, the enclosure monitor circuitry on each BCC utilizes SCSI address 15. This is allowable since each BCC is connected to a separate SCSI bus. However, when the enclosure configuration is in Full Bus mode, and the separate SCSI busses on the midplane are connected together and there are two BCCs in the enclosure, the secondary BCC does not connect to the SCSI bus. Disk Slots and Addressing The disk system has 14 available disk slots, SCSI addressing does not follow a "1-to-1" relationship between slot positions and SCSI addresses. Slot assignments and SCSI addresses are shown in Figure 49. Configuration In full bus mode, the SCSI address 7 is reserved for the host bus adapter. If more than one host bus adapter connects the disk system to other hosts, then a disk module must be removed from the slot whose SCSI address corresponds to the SCSI address of the additional host bus adapter. The most host bus adapters supported on this disk system is two. In split bus mode, the loading sequence is from slot 1 to the right to slot 7 and from slot 8 to the right to slot 14. In full bus mode, begin loading the disk modules in slot 1 and continue installing disk modules toward the right. Configuration 89
