IBM TS3100 Service Manual

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 are as follows: DTE
assignments are shown in Figure 17.
STE assignments
v Logical Library 1: Slot 1 through slot 9 4096 (x1000) through 4104 (0x1008)
v Logical Library 2: Slot 10 through slot 21 4096 (x1000) through 4107 (0x100B)
v Logical Library 3: Slot 22 through slot 33 4096 (x1000) through 4107 (0x100B)
v Logical Library 4: Slot 34 through slot 45 4096 (x1000) through 4107 (0x100B)
SCSI element addressing
Every logical library starts at the first drive slot with the current assigned element start address (default
value 256). It is 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 continues to have the addresses assignments 256 and 257, thus causing no interruptions
to their operation. Drive slots are still incremented by 1 for each drive slot position.
Note: Exchanging drives with different form factors results in the need for library reconfiguration.
