Hello Dennis,

Do I understand that you have an auto-loader (with a single SCSI port)
that can eject the entire magazine?  Sorry if this question sounds
simplistic; I'm still learning about auto-loaders.

A number of backup applications use the Load Unload command issued to
LUN 1 to direct ejection of the magazine in our Autoloader.

I looked in the standards for language supporting the use of the Load
Unload command to direct ejection of a magazine from a tape autoloader.
It doesn't seem like anything in SSC or SMC specifically addresses this
issue.

This becomes more of an issue in attached media changers, where one
device server processes SSC and SMC commands.  A possible solution would
be adding an optional bit to Load Unload to specify unloading the medium
or the magazine.

It seems to me that this should be specified in the standards and I
wonder if I missed something, and if not, if there would be support to
formalize the command to specify ejecting autoloader magazines.
