5-8 Archive Operations 601354 Rev A
Standard Audit During a Standard Audit, VolServ commands the robot to look
into each specified bin and to read the external label on any
medium present. Thus, the actual content of each bin is
compared against the VolServ database. Depending on the
number of bins to audit, a Standard Audit can take a long time
to complete.
There are archive-dependent differences that exist in the way a
Standard Audit is performed.
The DataTower archive provides the most autonomous Standard
Audit capability of all supported archives. When a Standard
Audit command is sent, the archive commands a robot to scan
each bin for media, builds a list of media found, and performs a
set of synchronizing operations to update its own database.
The archives send the list of media found with the results of
their own database synchronization actions to the VolServ host
computer. For the DataTo wer archive, a list of mounted media is
also appended to the list of media found. VolServ software then
performs its own set of synchronizing operations.
VolServ software performs two operations whenever a
StorageTek ACS product family Standard Audit is requested.
The archives send the cumulative discrepancy report that is used
by VolServ software to update its database. VolServ then sends
a request for a total inventory list (for example, a remap
operation). This information is used to update the VolServ
database, if necessary. That is, a Standard Audit command
results in a discrepancy report and a map list for use by VolServ
software.
Note
When audited, the entire DataTower archive is scanned.
