Reserve Command Element List Descriptors
Each element list consists of zero or more descriptors. The element list
descriptor defines a series of elements beginning at the specified element
address for the specified number of elements.
If the number of elements is zero, the element list begins at the specified
element address and continues through the last element address on the
unit. However, if the Element Address is a transport device (a picker) or
an unused Element Address, a status of CHECK CONDITION, Sense
Key = ILLEGAL REQUEST is returned.
