Archive media class computed capacity limits are “soft”, that is,
they can be exceeded when media are imported or moved in
from another archive. If automigration is specified, media of
this MediaClass group is then marked for movement to their
target archive. The media type capacity designates the “hard”
limit when entering media into an archive.
Media can only reside in an archive if their associated
MediaClass group has an archive media class assignment in that
archive.
An archive media class computed capacity is refigured if the
capacity of a MediaClass group changes.
Checks to determine if the high mark has been reached or
exceeded or the low mark has been reached or passed occur:
• After any Eject, Enter, Reclassify, or Modify Archive
Media Class command executes.
• After the MediaClass group or archive media class
association are redefined.
The sum of all archive media class capacities can exceed the
archive’s physical ability to house media. If VSID_CAPACITY
values are set unrealistically high and VSID_HIGH_MARK is
similarly high, the archive may physically completely fill
before any automigration procedure is triggered.
Components listed as preferred for storage of media of this
MediaClass group do not have exclusive ownership of those
components.
The total length of time the API software waits for a command
status in synchronous mode from VolServ is
(VSID_RETRY_LIMIT plus 1) multiplied by
VSID_TIMEOUT_VALUE.
