system and the inventory of cartridges. The database is kept in the memory of the Library control hardware.
Cartridge Storage
The Dell PowerVault 136T LTO Library contains cartridge storage slots in addition to any tape drives installed.
Storage Slot Numbering
The following convention is used to identify the coordinates of each Library element (storage slots or drives).
Table 2. Storage Slot Coordinates
The columns are numbered 1 to 5 from the mailbox column and continuing clockwise. The magazines within each column are designated A to C
from top to bottom. The rows within each magazine are numbered 1 to 6 from top to bottom for the LTO media type. The Drive magazine is
designated A to F from bottom to top. See Figure 3 below.
Figure 3. Storage Column Configurations and Coordinate system
NOTE: The fixed slot in columns 2, 4, and 5 does not have a magazine designation and is always numbered 0 so the coordinate for the
fixed slot in column 2 would be 2-0 (the "-" indicates no magazine is present). The Drive column (3) can have up to six drives. The magazine
letter can be A through F.
To manipulate the media within the library, the host must reference each movement with source and target designations. This is done via element
addressing, which specifies precisely which slots within the library are to be used. The following addressing scheme is used for the library.
