Migration Priority and Archive
When the archive media class action mode migrate option is
selected, a migration priority is assigned to the archive media
class. This value is used only during media type migration.
When media type migration begins, media from the highest
priority archive media class are first moved to the source
archive Eject list. If additional media must be ejected to meet
the media type low mark, the media class with the next highest
migration priority is chosen for processing.
The migration archive is the target archive for all media ejected
because media class migration or media type migration. As a
medium or media are removed from the source archive for the
purpose of migration, the destination archive (or migration
archive) Console ENTER button is highlighted.
Preferred Media PlacementWhen preferred media placement entries (DataShelf archive
only) are defined for a Media Class, VolServ directs placement
of media entered into that media class to a particular area in an
archive.
When a medium is entered into an archive for any reason
(import, checkin, move, migrate) or dismounted from a drive,
VolServ software checks if its media class is configured for
preferred placement. If it is, VolServ software directs
placement to a specific area in the archive. Note that preferred
placement values override the archive fill mode made during
archive configuration.
Entries in this field are four integers, separated by commas. Its
form is #,#,#,#. The entries stand for row, column, shelf, and
bin.
The primary use of preferred placement is to ensure that media
in a particular media class are placed near a system resource,
such as drives.
