Figure 20 shows the relationship between the DBAs and the locations of
the drives and controllers in the library.
Notes:  All component identifiers are numbered consecutively by
type, starting at 1.
 DBAs are numbered from the bottom up, with DBA 1 being
the bottom-most location.
 In a T380 with TS11xx technology drives, it is possible that only
the top DBA is installed. This DBA is numbered as DBA 3.
 Drives are numbered from left to right and bottom to top in a
DBA, as viewed from the back of the library. Each DBA can
hold up to four drives.
