moves the subject media into the archive and places 
them on the eject list (AML/E, AML/2, AML/J, or 
StorageTek ACS Product Family archives)

When an intransit medium (due to an incomplete mount 
command) is imported or entered, VolServ software attempts to 
complete the mount. 

VolServ supports two manual archives: the DataShelf archive 
and the Stage archive.

Configuring a manual archive is identical to configuring an 
automated archive with the following exceptions.

Fill Mode

When media are added to a DataShelf archive, VolServ must 
assign an empty storage bin for each new media.

To minimize database access activity, VolServ software caches 
information about an entire shelf of bins in memory. As long as 
an available bin exists in the cached shelf, VolServ software 
assigns storage bins from the cached shelf to new media.

When no additional bins are available in the cached shelf, 
VolServ software writes the cached information about the shelf 
to the database and scans the shelves in the DataShelf archive 
sequentially until another shelf with an available storage bin is 
located.

Two algorithms are available to determine where VolServ 
begins its scan for a shelf with an available storage bin. These 
algorithms, called fill modes, are wrap and first fill.
