Tandberg SLR Autoloader SCSI Functional Specifications 1-1
1 Overview
The purpose of this specification is to provide a definition of the SCSI
implementation for the Tandberg Data SLR Loader medium changer device.
For SCSI implementation information regarding the SLR tape drives (Data
transfer element), refer to the SLR7-140 Programers Manual: SCSI-2
Interface Functional Specifications Tandberg Data P/N 430743.
The SLR Loader consists of one medium changer device, one SLR tape drive,
one eight-cartridge removable magazine, and an integrated bar code reader.
The medium changer and the tape drive are single LUN SCSI devices, each
occupying a unique SCSI address. The individual SCSI address of the
autoloader and the internal drive are programble from the front pannel of
the unit. The SLR Autoloader supports both Single-ended and LVDS SCSI
interfaces as standard. The dual SCSI connectors on the back of the unit are
the standard SCSI-3 68-pin high-density connectors. Refer to the SLR
Autoloader Installation Manual (Tandberg Data P/N 432177 (SLR60-140))
for details on SCSI addressing, interconnect, termination, and cabling
considerations.
All SLR Loader configurations utilize three of the medium changer element
types defined in the SCSI Standard - one data transfer element (the tape
drive), one medium transport element (the cartridge picker/elevator), and
the storage elements (one for each magazine slot).
The SLR Loader operates in either sequential or random access mode,
depending on the configuration stored in its non-volatile memory. In
random access mode, cartridges are moved to and from the tape drive by
issuing the SCSI MOVE MEDIUM command to the medium changer device.
In sequential mode, cartridges are sequentially moved by issuing the SCSI
UNLOAD command to the tape drive (after manually loading the first tape).

The INITIALIZE ELEMENT STATUS command will cause the medium
changer to check any relevant element status. A subsequent READ
ELEMENT STATUS command may be used to retrieve element status
information. Since the medium changer always maintains the current
element status information, the default operation of this command only
determines if the changer is ready.
Mode
The setting of the Mode field defines whether or not an inventory is
performed by this command:
Mode Description
00b Do not re-inventory elements or bar codes, use current valid element status
01b Re-inventory bar codes only, if bar code reader is enabled
10b Do not re-inventory elements or bar codes, use current valid element status
11b Re-inventory all elements and bar codes, if bar code reader is enabled

The INITIALIZE ELEMENT STATUS WITH RANGE command will cause
the medium changer to check the status of the requested range of elements.
A subsequent READ ELEMENT STATUS command may be used to retrieve
element status information. Since the medium changer always maintains
the current element status information, the default operation of this
command only determines if the changer is ready.
Range
A Range bit of zero indicates that all elements are to be initialized. A Range
bit of one indicates that the range of elements specified by the Element
Address and the Number of Elements fields are to be initialized.
Element Address
This field specifies the address of the element or the starting address of the
range of elements to be checked. This field is ignored when the Range bit is
zero.
Number of Elements
This field specifies the maximum number of elements to be checked. This
field is ignored when the Range bit is zero.
Mode
The setting of the Mode field defines whether or not an inventory is
performed by this command:
Mode Description
00b Do not re-inventory elements or bar codes, use current valid element status
01b Re-inventory bar codes only, if bar code reader is enabled
10b Do not re-inventory elements or bar codes, use current valid element status
