- Qualifier: set to zero to indicate that the LUN specified in the Command Block is currently supported.
- Peripheral Device Type: set to zero to indicate that the device is Direct Access.
- Page Code: set to the value of the page code field in the CDB.
- Page Length: This field is set to 60 (3Ch), and specifies the length of the following page data.
- WSNZ - Write Same No Zero: set to zero which indicates the device server supports a value of zero in the
NUMBER OF LOGICAL BLOCKS field in the WRITE SAME command CDB.
- Maximum Compare and Write Length: set to zero which indicates the device server does not support the
COMPARE AND WRITE command.
- Optimal Transfer Length Granularity: set to zero to indicate that the device server does not report optimal
transfer length granularity..
- Maximum Transfer Length: set to zero which indicates there is no reported limit on the maximum transfer
length in logical blocks that the device server accepts for a single request using any of the following supported
media access commands: PREFETCH, READ, VERIFY, WRITE, WRITE AND VERIFY.
- Optimal Transfer Length: set to zero which indicates there is no reported value for the optimal transfer length
in logical blocks for any of the following supported media access commands: PREFETCH, READ, VERIFY,
WRITE, WRITE AND VERIFY.
- Maximum Prefetch XDRead XDWrite Transfer Length: indicates the maximum transfer length in logical
blocks that the device server accepts for a single PRE-FETCH command. It is set to zero to be less than or
equal to the Maximum Transfer Length (above).
- Maximum Unmap LBA Count: set to 0000_0000h to indicate that the device server does not implement the
UNMAP command.
- Maximum Unmap Block Descriptor Count: set to 0000_0000h to indicate that the device server does not
