Parameter
Pointer
SDLT and DLT must be 0.
For LTO only: The Parameter Pointer field allows the host to specify at which
parameter within a log page the requested data should begin. For example, if a
page supports parameters 0 through 5, and the Parameter Pointer contains 3,
then only parameters 3, 4, and 5 are returned to the initiator. Similarly, if a page
supports parameters 1, 3, and 6, and the Parameter Pointer contains 2, then
only parameters 3 and 6 are returned to the initiator.
If the Parameter Pointer is larger than the highest numbered parameter on the
page, then the target terminates the command with CHECK CONDITION
status, sense key set to ILLEGAL REQUEST, and additional sense code set to
INVALID FIELD IN CDB.
Note that parameters within a page are always returned in ascending order
according to parameter code.
If the target does not support a parameter code within this page, then it does
not return any data associated with this parameter.
Allocation
Length
This field specifies the maximum number of bytes that the initiator has
allocated for returning data. The host uses this field to limit the size of data
transfers to its own internal buffer size.
