Library Management Software
The library management software controls the library hardware to mount and
dismount cartridges on drives and move the robot. When the library is in automated
mode, these operations occur without manual intervention. The software determines
the location of the cartridge by accessing the audit data uploaded from the library. The
software then allocates the drive to receive the cartridge.
These application maintain a database that tracks volume serial numbers (VOLID) of
cartridges and their current locations in the library.
Host Software Component
When an SL8500 library is in a configuration with a Multiple Virtual Storage (MVS)
host, the host must run a version of the StorageTek Host Software Component (HSC)
along with the Storage Management Component (SMC). HSC resides in the MVS host,
but is invisible to the actual operating system. HSC 6.0 or higher is required for host
control. However, for new drives, higher levels of HSC may be required.
ACSLS
ACSLS is a software package that manages library contents and controls library
hardware for the mounting and dismounting of cartridges. ACSLS 7.1 or higher is
required. This application provides library management services such as cartridge
tracking, pooling, reports, and library control.
Library Partitioning
Note – Library partitioning is a licensed feature which must be enabled by your Sun
service representative. This feature is available starting with SL8500 firmware version
3.7x and StreamLine Library Console version 3.25. See “System Requirements for
Library Partitioning” on page 24 for complete details.
Library partitioning allows SL8500 rails (LSMs) to be partitioned for exclusive use by
separate hosts. For example, you can configure some rails to be used only by an HSC
host and others to be used only by an ACSLS host. This allows you to configure an
SL8500 library for applications running on multiple operating systems.
Following are important features and restrictions of library partitioning.
