WHAT YOU SEND TO THE AUTOLOADER
 If an initiator has reserved the cartridge loader, the autoloader returns
Reservation Conflict (18h) status to the following commands from another
initiator:
 INITIALIZE ELEMENT STATUS
 INITIALIZE ELEMENT STATUS WITH RANGE
 MOVE MEDIUM
 POSITION TO ELEMENT
 SEND DIAGNOSTICS (except Page Code 00h, Supported pages)
20.2 WHAT YOU SEND TO THE AUTOLOADER
20.2.1 SIX-BYTE CDB (PAGE CODE 16h)
Use the six-byte CDB if you want to reserve the autoloader as a unit or specific
elements within the autoloader.
Element – Byte 01, Bit 0
This field specifies whether you are reserving the entire autoloader or a series
of autoloader elements, as follows:
0 – Reserve the entire autoloader.
1 – Reserve a series of elements, identified by the Reservation Identification
field (byte 02) and specified by the Element List Descriptor.
Reservation Identification – Byte 02
This field allows you to assign an identification number to a reservation
request that reserves a series of elements. You can assign any one-byte number
you want. You can use this number with the RELEASE (17h) command to
release the same series of elements (see Chapter 17 for more information).
Element List Length – Bytes 03 and 04
This field specifies the total length in bytes of the element list descriptors that
you are sending. Each element list descriptor is 6 bytes, so the valid values for
this field are 0, 6, and increments of 6.
The maximum value for this field is 36h (54 =9 x 6), where 9 is the maximum
number of elements and 6 is the number of bytes required for each element list
descriptor
If the Element field (byte 01, bit 0) is 0, this field is ignored.
If the Element field (byte 01, bit 0) is 1 and the value for the Element List
Length field is 0, no elements are reserved.
