Number of Elements
Reserved (00h)
The Logical Unit Number must be set to 0. This field indicates
which logical unit the command should be sent to.
A Range field of 1 specifies performing the inventory over the
range specified by the Starting Element Address and Number of
Elements fields. A value of 0 specifies performing the inventory on
all elements in the library, ignoring the Starting Element Address
and Number of Elements fields.
These fields are used to select the range of elements to be
inventoried and are only valid when the Range field is 1. The
inventory range begins with the first element with an address
greater than or equal to the Starting Element Address, and
includes all defined elements until the indicated number of
elements have been inventoried or the last element is reached.
A No bar code Labels field of 1 specifies the inventory to not scan
the bar codes of the elements and set the corresponding primary
volume tags to empty. A value of 0 specifies element bar code
labels are to be scanned and placed in the primary volume tags.
