TS3100 Tape Library and TS3200 Tape Library Setup, Operator, and Service Guide
one or two half high drives, there are four potential drives in the space that used
to occupy two. As a result, the first half high drive position, or the first full-high
drive position, will be called "Drive 1". The second half high drive position will be
called "Drive 2". The third half high drive position, or the second full high drive
position, will be called "Drive 3". The fourth half high drive position will be called
"Drive 4".
Important: In a 4U library a full high 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 high drive sled should never be installed in
drive slot 2 (drive will occupy slot 2 and slot 3).
Mixing of Drives
The library supports a mix of full high and half high drives in the same physical
library and the same logical library. They 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 3-1.
STE assignments:
v Logical Library 1: Slot1 through 23 4096 (0x1000) through 4118 (0x1016) as
shown in Figure 3-4 on page 3-6

Configuration of a 2 - Partition System
A two partition system must have at least two drives installed. One drive must be
installed in either drive position 1 or drive position 2, and another drive must be
installed in either drive position 3 or drive position 4. Partition 1 contains any
drives in drive position 1 and drive position 2. Partition 1 will also contain
Drive 4
