Initial
Configuration
• The migrate action mode is selected, media within an
archive media class are subject to migration to another
archive associated with the same media class. Migration
continues until the low mark is reached, provided that
enough space exists in the destination archive media class to
accept the migrated media. Notification is also sent to the
Volume Server SysLog Console.
At this point, it is important to describe the media class
migration and media type migration processes.
Media Class
Migration Media class migration is a process directed by VolServ
software. The process begins if a media class migrate action
mode was selected during archive media class creation and the
media class fill level reaches the media class high mark
threshold.
Several operations can cause a Media Class fill level to exceed
its high mark threshold. Some of these are import, reclassify, or
bulk loading operations.
When media class migration starts, VolServ software places
media from the source media class on its archive eject list. The
quantity of eject list entries equals the difference between the
actual fill level that triggered the process minus the media class
low mark threshold. The archive Console display EJECT
button of the source archive is then highlighted.
The media selected for ejection are those with the oldest access
date. This value correlates to the last time the medium was
entered, mounted, or dismounted.
When a medium is ejected by the AO, the migration archive
enter list is appended with that same medium. The archive
Console display ENTER button of the migrations archive is
highlighted.
