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 

b

in 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 DataTower 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. 

When audited, the entire DataTower archive is scanned.
