[. . . ] Element Type Code The element type code field specifies the element type(s) selected for reporting. The element type codes are defined as follows: Code 0h 1h 2h 3h 4h 5h-Fh Description All element types reported Medium Transport Element Storage Element Import Export Element Data Transfer Element Reserved Starting Element Address The starting element address specifies the minimum address to report. Only elements with an element type code permitted by the element type code specification and an element address greater than or equal to the starting element address shall be reported. Element descriptor blocks are not generated for undefined element addresses. Number of Elements The number of elements specifies the maximum number of element descriptors to be created by the target for this command. If the allocation length is not sufficient to transfer all the element descriptors, the target shall transfer all those descriptors that can be completely transferred and this shall not be considered an error. Tandberg SLR Autoloader SCSI Functional Specifications 2-29 Tandberg Data SCSI Commands ______________________________________________________________________ 2. 10. 1 Element Status Data Header The element status data consists of an eight-byte header followed by one or more element status pages (one for each element type). Each element status page includes an eight-byte header followed by one or more element descriptors (one for each element address). The data shown for the Element Status pages assumes that the command was specified in such a way that all descriptors for a given element type would be returned. The format of the Element Status Data Header follows: Bit Byte 0 1 2 3 4 5 6 7 7 6 5 4 3 2 1 0 First Element Address Reported (MSB) First Element Address Reported (LSB) Number of Elements Available (MSB) Number of Elements Available (LSB) Reserved (MSB) Byte Count of Report Available (LSB) First Element Address Reported The first element address reported field indicates the element address of the element with the smallest element address found to meet the request in the command descriptor block. Number of Elements Available The number of elements available field indicates the number of elements meeting the request in the command descriptor block. The status for these elements is returned if sufficient allocation length was specified. Byte Count of Report Available The byte count of report available field indicates the number of bytes of element status page data available for all elements meeting the request in the command descriptor block. This value shall not be adjusted to match the allocation length available. 2-30 Tandberg SLR Autoloader SCSI Functional Specifications Tandberg Data SCSI Commands ______________________________________________________________________ 2. 10. 2 Medium Transport Element Status Page The Medium Transport Element Status page includes an eight-byte header followed by one element descriptor. The format of the Medium Transport Element Header follows: Bit Byte 0 1 2 3 4 5 6 7 7 6 5 4 3 2 1 0 Element Type Code (1 = Medium Transport Element) PVolTag AVolTag Reserved Medium Transport Element Descriptor Length (MSB) Medium Transport Element Descriptor Length (LSB) Reserved (MSB) Byte Count of Descriptor Data Available (LSB) The format of the Medium Transport Element Descriptor follows: 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Element Address (MSB) Reserved Except Element Address (LSB) Reserved Full Reserved Additional Sense Code Additional Sense Code Qualifier Reserved Reserved Reserved SValid Invert Reserved Source Storage Element Address (MSB) Source Storage Element Address (LSB) Reserved Reserved Reserved Reserved PVolTag The primary volume tag (PVolTag) bit of one indicates that the primary tag information field is present in the following element descriptor. A value of zero indicates that these bytes are omitted from the element descriptor. AVolTag The alternate volume tag (AVolTag) bit of one indicates that the alternate tag information field is present in the following element descriptor. A value of zero indicates that these bytes are omitted from the element descriptor. Element Descriptor Length The element descriptor length field indicates the number of bytes in each element descriptor. Tandberg SLR Autoloader SCSI Functional Specifications 2-31 Tandberg Data SCSI Commands ______________________________________________________________________ Byte Count of Descriptor Data Available The byte count of descriptor data available field indicates the number of bytes of element descriptor data available for elements of this element type meeting the request of the CDB. The value shall not be adjusted to match the allocation length available. Element Address The element address field gives the address of the medium changer element. Except An exception (Except) bit of one indicates the element is in an abnormal state. An Except bit of zero indicates the element is in a normal state. [. . . ] The '?' character will match any single character.

If the logical unit is ready, the command returns a GOOD status. The library will report CHECK CONDITION status with the sense key set to NOT READY for the following conditions: during the power-on initialization process, when a magazine door is opened, or when the library is in front panel mode. 2-52 Tandberg SLR Autoloader SCSI Functional Specifications Tandberg Data SCSI Commands ______________________________________________________________________ 2. 18 Bit Byte 0 1 2 3 4 5 6 7 8 9 7 WRITE BUFFER 3Bh 6 5 4 3 2 1 0 Logical Unit Number (MSB) Operation Code (3Bh) Reserved Buffer ID Buffer Offset Mode (LSB) (MSB) Transfer Length Vendor Unique Reserved Flag (LSB) Link The WRITE BUFFER command is used to download firmware to the medium changer device. This command should only be used by qualified service personnel. NOTE: Prior to issuing this command, the medium changer device must be placed in Flash Update Mode by entering the front panel Menu and selecting Flash Update. [. . . ]
