using full-bus configuration, the even-numbered slots are assigned SCSI IDs 0 - 4, and the odd-numbered slots are assigned IDs 8 - 12. (The gap in addresses is necessary for internal management of enclosure components.) If the disk enclosure is configured for split-bus operation, the both the even-numbered slots and the odd-numbered slots are assigned IDs of 0 - 4. • When viewing status information for the disk array, you may also see the disk enclosure number and slot number displayed. These parameters identify the physical location of the disk module within the disk array. The disk enclosure number is assigned during installation using the disk enclosure ID switches located on the rear of the enclosure. Each disk enclosure in the disk array must have a unique enclosure ID number. Disk enclosures should be numbered from the top down, with the enclosure mounted highest in the rack being 0. The slot number indicates the physical enclosure slot in which the disk module is installed. This number is related to, but is not the same as the disk SCSI ID. Slots are assigned SCSI IDs differently depending on whether the disk enclosure is configured for full or split bus operation as described above. Figure 72 illustrates the four components involved in disk module addressing. Managing Disk Array Capacity 191 Managing the Disk Array
