4.4.1 Mount Media Message:
The Mount Media Message is used to notify the requester that the Mount Media
Command successfully completed or that an error occurred causing the command to
fail. With a Mount Command, it will return the drive position the tape label was
moved to (0-9 bottom to top) and the slot position the tape label was moved from. A
–1 (a 255 will be in both bytes) means that no change occurred. The first byte of the
Reserved 4 field will have an X, which stands for mount update. The structure of the
Mount Media Message, its arguments and an example are listed in Table 4-8.
