3-26 Initial Configuration 601354 Rev A
Although not enforced by VolServ software, there is one
restriction that should be applied to archive class percentage
when media migration is planned. This restriction is there
should be no Media Class overlap. Using the figure in “Archive
Class Percentage” on page 3-24, the capacity of the Automated
Archive should equal the total capacity of the Blank Media
Class Group and portions of Media Class Groups A and B that
are associated with the Automated Archive.
Action Mode,
Low Mark, High
Mark
The specification of action mode, low mark, and high mark is
made for each archive media class, as well as for each media
type in a configured archive. As suggested by low mark and
high mark, action may or may not be triggered when the amount
of media in an archive media class reaches a calculated low
mark or high mark threshold.
The SA can choose action modes of none, notify, or migrate.
Depending on the action mode option selected, either no
notification, or migration of media from one archive to another
occurs when the archive media class high mark threshold is
reached.
During some operations, media are removed from an archive.
When this occurs, the media removed from an archive may
cause an archive media class fill level to reach its low mark
threshold. If the notify action mode is selected, a notification is
sent to the Volume Server SysLog Console and appropriate
archive Console.
A few operations result in adding media to an archive and result
in exceeding the high mark threshold for the archive media
class fill level. When the fill level reaches the high mark
threshold and:
• The notify action mode is selected, a notification is sent to
the Volume Server SysLog Console.
