Initial Configuration

601354 Rev A

After all archives at a site are successfully configured and 
registered with VolServ, at least one drive must be defined and 
associated with an archive. 

The Create Drive command is used to define a drive; four 
drive statistics are associated with it. These are the usage count, 
current usage time, total usage time, and error count. These 
built-in statistics are provided by VolServ software, but only the 
usage count is automatically updated by VolServ software. 
Usage count indicates the number of times that media are 
mounted to a drive. 

VolServ clients are responsible for keeping the other three 
statistics values updated. It is recommended that they be 
defined as follows: 

•

Current usage time indicates read/write operation time in 
seconds since the latest preventive maintenance

•

Total usage time indicates the read/write operation time in 
seconds since the drive definition

•

Error count indicates the number of read/write errors

All statistics are initialized to zero when a drive is defined. Two 
of these statistics are cleared when a drive is varied to an 
on-line state. Refer to 

Drive definition is performed via the GUI. Its parameters 
consist of the drive ID and media type that the drive supports. 
After a drive is defined, it cannot be changed. It must be deleted 
and defined again. 

VolServ has to be running to define a drive.
