READ ATTRIBUTE Command (8Ch) SDLT 600 SCSI Interface Guide

4-178 January 2005 81-81200-02 REV A01

that most recently sent a WRITE ATTRIBUTE command to the drive while this medium auxiliary

memory was accessible.

APPLICATION NAME: The name of the application client.

APPLICATION VERSION: The version of the application client.

USER MEDIUM TEXT LABEL: The user level identifier for the medium.

DATE & TIME LAST WRITTEN: Contains when the application client last wrote to the medium

auxiliary memory. The format is YYYYMMDDHHMM; that is, four numeric ASCII characters for the

year followed by two numeric ASCII characters for the month followed by two numeric ASCII

characters for the day followed by two numeric ASCII characters between 00 and 24 for the hour

followed by two numeric ASCII characters for the minute with no intervening spaces.

TEXT LOCALIZATION IDENTIFIER: Defines the character set (see Table 4-105) used for

attributes with a TEXT format. At this time, Super DLTtape only supports the ASCII character set.

BARCODE: The contents of a barcode associated with the medium in the medium auxiliary memory.

OWNING HOST TEXTUAL NAME: Indicates the host from which the USER MEDIUM TEXT

LABEL originates.

MEDIA POOL: Indicates the media pool to which this medium belongs.

PARTITION USER TEXT LABEL: A user-level identifier for the partition specified by the

Partition Number field in the CDB.

LOAD/UNLOAD AT PARTITION: Indicates whether the media can be loaded or unloaded at the

partition specified by the Partition Number field in the CDB.

Support for Host Vendor-Unique Attributes

SDLT tape drives allocate a fixed size (1,029 bytes) for the host to write its host vendor-unique EMAM

attributes. These attributes can be numbered in the range 1400h through 17FFh. Since attribute headers

are 5 bytes in length, if the host wants to write one attribute, there are 1,024 bytes of attribute data

space available. If the host wants to write two attributes—one maximum and one minimum—the

largest the maximum can be is 1,029 (total) – 5 (max attribute header) – 5 (min attribute header) – 1

(min attribute data) or 1,018 data bytes, and the smallest the minimum can be is 1 byte.
