Mixed media library
An Ultrium or SDLT library at firmware level 2.0 or greater, can be converted into
a mixed-media library by exchanging existing panel 1; panels 1 and 2; or panels 1,
2, and 3 for the type of media panel not yet in the library. Mixed-media libraries
require library partitioning, with one media type per partition. Refer to HP
StorageWorks Interface Manager and Command View TL Users Guide to learn
about and use library partitioning. Removable magazines are also required in a
mixed-media library.
These requirements impact library operations in the following ways:
■
If you convert panel 1 only to a new media type, neither load port can be used
to insert or remove media from that panel. Because the left and right load
ports are on panels 2 and 5, they must have the same media type as the rest of
panels 2 and 5.
■
If panels 1 and 2 (or 1, 2, and 3) are converted to a new media type, the left
load port can be used to insert or remove media from the converted panels.
The right load port is used to insert or remove media from the existing panels.
■
The type of media added to your library is on the left side of the library only;
therefore, the additional media type has only one column of load port
capacity, and the existing media type has two columns of load port capacity.
These are important when determining the library storage capacity. Storage
capacity in a mixed-media library depends on the quantity of panels exchanged,
the location of media types you are using, whether the load ports are enabled, and
the number of drives in the library.
Note: In order to use mixed media, the library must be at firmware revision level 2.0 or
greater. Update the firmware before installing mixed media in the library.
