Table 3 Sampling of Media Type Identifiers
Identifier Media Type Media Domain
“L4” as the last two characters in the
barcode
LTO-4 LTO
“LU” as the last two characters in the
barcode
LTO-4 WORM LTO
“L5” as the last two characters in the
barcode
LTO-5 LTO
“LV” as the last two characters in the
barcode
LTO-5 WORM LTO
With a valid media type identifier present and the Media Type Checking setting enabled, which is
the case by default, a host is prevented from executing invalid media moves across differing media
types. For example, a host can be prevented from moving LTO-5 media to an LTO-4 drive. If an invalid
move is attempted, the library returns an error to the host.
Returning media identifiers to hosts
With the Return Media Identifier setting, you can control if and where a media type identifier appears
in the volume serial number that is returned to the host.
Table 4 shows an example of how the return media identifier behaves, depending on the setting you
choose: Disabled, Prefix, Suffix, and Pass Through. The bold, underlined portion is the media identifier.

Working with Library Control Paths
You must define a control path for each library partition. The control path is used to connect a partition
to a host application. The ESL G3 does not automatically assign a control path when you create a
partition. When selecting a library control path for a partition, you are selecting which tape drive
will present (or proxy) the virtual robot LUN to the SAN and hosts.
Creating Partitions
You can create library partitions in the following ways:
