Element Address Assignment Page (1Dh)
The Element Address Assignment mode page returns the first element address and the element quantity
for each element type. The quantity is based on the number of elements configured in the library, some of
which may be temporarily removed (like a storage magazine or drive). Elements that are temporarily
removed will not change the overall number of elements for that element type.
Table 41 shows the format
of the page. Initiators should always retrieve this page and use these values when communicating element-
based commands with the library. The addresses and quantities of elements should never be assumed or
hard-coded by the initiator, as they are subject to change.
Parameters Savable (PS) – This page is not savable, and this field is set to zero.
Page Code – This field identifies the Element Address Assignment mode page and returns 1Dh.
Parameter List Length – This field is set to 12h (18).
First Medium Transport Element Address – This returns 0001h, which is the address of the first medium
transport element (accessor).
Number of Medium Transport Elements – This field returns 0001h.
