Step 6 Install the client application on the client PC and configure it to work with the appropriate Port-
Target-LUN.
Step 7 Now, the Scalar DLC software is ready to accept commands from a SCSI client.
General Characteristics
The Scalar 1000 components include:
• Control Module (CM) - a single cabinet containing an Insert/Eject station, storage cells, and tape
drives. The CM uses one or two SCSI ports to connect to a SCSI host.
• Expansion Module (EM) - a single cabinet that is added to a CM to provide additional storage cells
and tape drives. The Scalar 1000 can have up to three EM’s.
• Operator panel - displays status and provides command entry.
• Accessor - a device that moves cartridges to and from the Insert/Eject station, storage cells, and
tape drives.
• Barcode scanner - reads cartridge barcode labels to identify library volumes.
The Scalar 10K components include:
• Control Module (CM) - a cabinet that attaches to the AM. It contains storage cells, tape drives, and
the library Operator LCD Panel that displays library status and provides a command entry point. The
CM uses one or two SCSI ports to attach SCSI hosts.
• Accessor Module (AM) - a cabinet that contains four rack locations (Control Module, Insert/Eject
stations, Tower Module, or Storage Cells), and the Accessor. Each AM can have an Expansion
Module added.
• Expansion Module (EM) - a cabinet that is added to an AM or to another EM to provide additional
storage cell configurations and attachment capabilities for DMs and TMs. The Scalar 10K can have
up to three EM’s.
• Accessor - located in the AM, it is a device that moves cartridges to and from Insert/Eject stations,
storage cells, or tape drives.
• Barcode scanner - located in the AM, it is a device that teaches the system configuration, and reads
cartridge barcode labels to identify library volumes.
• Drive Module (DM) - a cabinet that attaches to an AM or an EM. It contains a maximum of 48 drives.
• Tower Module (TM) - a cabinet that attaches to an AM or an EM. It contains rotating storage
locations.
Note
Either use LUN 0 or ensure that there already is a SCSI client configured for LUN 0 of
the specified target. Otherwise, even when everything is properly configured and
installed, the SCSI Client cannot be activated.
CAUTION
It is strongly not recommended either assign the non-SCSI client to the same
logical library, or use the library partitions as shared resources in other logical
libraries with the non-SCSI client assigned. Should that be done, some SCSI
features will not be available for the client, mostly because of home position
restrictions used in the Scalar DLC software for non-SCSI clients.
