that used to occupy two. As a result, the first half height drive position, or the first
full-high drive position, will be called "Drive 1". The second half height drive
position will be called "Drive 2". The third half height drive position, or the second
full height drive position, will be called "Drive 3". The fourth half height drive
position will be called "Drive 4".
Important: In a 4U library a full height drive sled may be installed in drive slot 1
(drive will occupy slot 1 and slot 2) or drive slot 3 (drive will occupy
slot 3 and slot 4). A full height drive sled should never be installed in
drive slot 2 (drive will occupy slot 2 and slot 3).
Mixing of Drives
The library will support a mix of full height and half height drives in the same
physical library and the same logical library. They will support a mix of drives in
the same physical library and the same logical library. They will also support a mix
of SCSI, SAS, and Fibre Channel in the same physical library and the same logical
library; however, mixing drive interface types in the same logical library is not
recommended.
Important: Drives that do not share a common media type cannot be mixed in the
same logical library. For instance, Gen 3 and Gen 6 drives cannot use
the same media and so they cannot be mixed. LTO 3 media cannot be
read on LTO 6 drives.
Configuration of a 1 - Partition System
A one partition system configured for a 4U library contains any and all drives
present in any drive positions, and it will contain all four magazines. When
configured with one logical partition, the Element Address assignments will be as
follows: DTE assignments will be as shown in Figure A-1
STE assignments
v Logical Library 1: Slot1 through 23 4096 (0x1000) through 4118 (0x1016) as
shown in Figure A-4 on page A-6
Configuration of a 2 - Partition System
A two partition system must have a minimum of two drives, but may have three
or four drives. Partition 1 will contain any drives in drive position 1 and drive
position 2. Partition 1 will also contain magazine 1 and magazine 2. Partition 2 will
contain any drives in drive position 3 and drive position 4. Partition 2 will also
contain magazine 3 and magazine 4.
