Configuration of a three - partition system Configuration of a 4 - Partition System A four partition system must have four drives. Each partition contains one drive and one magazine. When configured with four logical partitions, the Element Address assignments will be as follows: DTE assignments will be as shown in Figure 3-4.

Configuration of a four - partition system SCSI Element Addressing a77ug164 Every logical library starts at the first drive slot with the current assigned element start address (default value 256). It will be incremented from the bottom to the top slots for every drive slot. There is one exception to this addressing scheme to accommodate libraries currently in the field. A 4U library containing only full height drives will continue to have the addresses assignments 256 and 257, thus causing no interruptions to their operation. Drive slots will still be incremented by 1 for each drive slot position. Note: Exchanging drives with different form factors will result in the library needing to be reconfigured. Chapter 3.
