Source Storage Element Address: This field provides the address of the last storage element from which the tape cartridge was moved (valid only if the SValid bit is 1). Primary Volume Tag Information: When VolTag in CDB was set the media changer will return a 36 byte PVolTag Identifier. This identifier will contain the bar code label of the cartridge mounted in the tape drive. 0 1 2 3 4 5 6 7 n n n n n n t t The first six (6) characters are any combination of upper case A-Z or 0-9 (e.g. ABC123) to identify the cartridge volume. The last two (2) characters are determined by the cartridge media type (i.e. L for LTO and 1 for tape cartridge generation or drive manufacturer unique identifier). Code Set: If the DVCID bit is set in the CDB, the Code Set field is set to 2h, indicating that ASCII values are returned. If the DVCID bit in the CDB is set to 0, the Code Set is set to 0h. Identifier Type: If the DVCID bit is set in the CDB, the Identifier Type is set to 1h. This indicates that the identifier field contains an eight byte vendor identifier followed by vendor unique identifier information. If the DVCID bit in the CDB is set to 0, the Identifier Type field is set to 0h. Identifier Length: The Identifier Length field contains the length in bytes of the Identifier field. When the DVCID bit is not set in the CDB the Identifier Length field is set to 00h. Identifier: If the DVCID bit is set in the CDB, the Identifier field provides the Vendor ID, Product ID and tape drive serial number. The format is identifier Type 1, which is equivalent to the drive's Inquiry page 83h. If the DVCID bit in the CDB is set to 0, the Identifier field is omitted.
