SCSI Commands: 29BREAD ATTRIBUTE
ASSIGNING ORGANIZATION (ID 0005h): The ASSIGNING ORGANIZATION
attribute identifies the organization responsible for the specifications defining the
values in the FORMATTED DENSITY CODE attribute. The ASSIGNING
ORGANIZATION attribute contains the ASCII text LTO-CVE.
FORMATTED DENSITY CODE (ID 0006h): Contains one of the density code values
reported in the REPORT DENSITY SUPPORT command.
INITIALIZATION COUNT (ID 0007h): Indicates the number of times that a device
server has logically formatted the medium. This value is cumulative over the life of
the medium and shall not be reset to zero. This attribute is UNSUPPORTED.
VOLUME IDENTIFIER: (ID 0008h) Indicates the volume identifier (see SMC-3) of
the medium. If the device server supports this attribute but does not have access to
the volume identifier, it shall report this attribute with an attribute length value of
zero. This attribute is UNSUPPORTED.
DEVICE VENDOR/SERIAL NUMBER AT LAST LOAD (ID 020Ah), DEVICE
VENDOR/SERIAL NUMBER AT LOAD –1 (ID 020Bh), DEVICE VENDOR/SERIAL
NUMBER AT LOAD –2 (ID 020Ch) and DEVICE VENDOR/SERIAL NUMBER AT
LOAD –3: (ID 020Dh): Gives a history of the last four device servers in which the
medium has been loaded. The format of the attributes is shown in the table below.

T10 VENDOR IDENTIFICATION field is the same value returned in the
INQUIRY data.
PRODUCT SERIAL NUMBER field contains ASCII data representing the
drive serial number. This value is also reported in INQUIRY Page 80h.
TOTAL MBYTES WRITTEN IN MEDIUM LIFE (ID 0220h) and TOTAL MBYTES
READ IN MEDIUM LIFE (ID 0221h): Indicate the total number of data bytes that are
transferred to or from the medium, after any data compression has been applied,
over the entire medium life. These values are cumulative and shall not be reset to
zero. These values are expressed in increments of 1 048 576 bytes (e.g., a value of
one means 1 048 576 bytes and a value of two means 2 097 152 bytes).
TOTAL MBYTES WRITTEN IN CURRENT/LAST LOAD (ID 0222h) and TOTAL
MBYTES READ IN CURRENT/LAST LOAD (ID 0223h): Indicate the total number of
data bytes that are transferred to or from the medium, after any data compression
has been applied, during the current load if the medium is currently loaded, or the
last load if the medium is currently unloaded. The device server should reset these
attributes to zero when the medium is loaded. These values are expressed in
increments of 1 048 576 bytes (e.g., a value of one means 1 048 576 bytes and a
value of two means 2 097 152 bytes).
MEDIUM USAGE HISTORY (ID 0340h): Provides counters for the entire medium.
