Im a little confused as to why the library needs to
support tapealert for the backup software to clean
drives.

>From what ive read of the tapealert hp standard, the
drive firmware will monitor the drive and populate the
tapealert scsi log page with information which is
retrieved from the host (backup software) by
interogating the drive which in turn decides how to
respond to the information.

The response may be mount CLN000 into drive 0.
I dont see what role the robot plays in this
exchange that is any different to serving a
media mount request.

Can someone clarify? The only thing I can think
of is Netbackup does not attempt tapealert in all cases
and may be dependant on the robot type the drives are
connected to as defined in netbackup configuration
(i.e. TLD, ACS, etc). If this is the case there should
be some logical explanation.
