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).

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 00b 01b 10b 11b Description Do not re-inventory elements or bar codes, use current valid element status Re-inventory bar codes only, if bar code reader is enabled Do not re-inventory elements or bar codes, use current valid element status Re-inventory all elements and bar codes, if bar code reader is enabled 2-2 Tandberg SLR Autoloader SCSI Functional Specifications Tandberg Data SCSI Commands ______________________________________________________________________ 2.2 Bit Byte 0 1 2 3 4 5 6 7 8 9 7 INITIALIZE ELEMENT STATUS WITH RANGE E7h 6 5 4 3 2 1 0 Logical Unit Number Element Address (MSB) Operation Code (E7h) Reserved Range Element Address (LSB) Reserved Reserved Number of Elements (MSB) Number of Elements (LSB) Mode Reserved Reserved Flag Link 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 00b 01b 10b 11b Description Do not re-inventory elements or bar codes, use current valid element status Re-inventory bar codes only, if bar code reader is enabled Do not re-inventory elements or bar codes, use current valid element status Re-inventory all elements and bar codes, if bar code reader is enabled Tandberg SLR Autoloader SCSI Functional Specifications 2-3 Tandberg Data SCSI Commands ______________________________________________________________________ 2.3 Bit Byte 0 1 2 3 4 5 7 INQUIRY 12h 6 5 4 3 2 1 0 Logical Unit Number Vendor Unique Operation Code (12h) Reserved Page Code Reserved Allocation Length Reserved EVPD Flag Link The INQUIRY command requests that information regarding parameters of the medium changer be sent to the initiator. EVPD An enable vital product data (EVPD) bit of zero specifies that the target shall return the standard INQUIRY data. An EVPD bit of one specifies that the device shall return the vital product data based on the Page Code field. Page Code The page code field is used to specify which page of vital product data to return if the EVPD bit is set to one. Page Code 00h 80h Page Description List of supported VPD pages Unit Serial Number page Allocation Length This specifies the maximum number of bytes that the initiator has allocated for returned Inquiry data. An Allocation Length of zero indicates that no Inquiry data is transferred. This condition is not considered an error. The device will terminate the DATA IN phase when allocation length bytes have been transferred, or when all available Inquiry data has been transferred to the initiator, whichever is less. 2-4 Tandberg SLR Autoloader SCSI Functional Specifications Tandberg Data SCSI Commands ______________________________________________________________________ 2.3.1 Standard Inquiry Response The following information is returned in response to an INQUIRY command with the EVPD bit set to zero: Bit Byte 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32-35 36-46 47-51 52 53 54 55 7 6 5 4 3 2 1 0 Peripheral Qualifier RMB ISO Version AENC TrmIOP RelAdr Wbus32 Vendor ID Product ID Peripheral Device Type Device-Type Modifier ECMA Version ANSI-Approved Version Reserved Response Data Format Additional Length Reserved Reserved WBus16 Sync Linked Reserved CmdQue SftRe "T" or "O" or "X" "A" or "V" or "X" "N" or "E" or "X" "D" or "R" or "X" "B" or "L" or "X" "E" or "A" or "X" "R" or "N" or "X" "G" or "D" or "X" "S" or "L" or "X" "L" or "X" or "X" "R" or "B" or "X" "" or "" or "X" "A" or "" or "X" "U" or "" or "X" "T" or "" or "X" "O" or "" or "X" "L" or "" or "X" "O" or "" or "X" "A" or "" or "X" "D" or "" or "X" "E" or "" or "X" "R" or "" or "X" "" or "" or "X" "" or "" or "X" Firmware Revision Level Firmware Creation Date Vendor Unique Boot Code Revision Level Firmware Download Size Product Class Vendor Unique BarCode Peripheral Qualifier & Peripheral Device Type These fields identify the physical device currently connected to the logical unit.
