The selection of media for migration is dependent on both 
Media Classes and media types. Refer to VolServ: Introduction, 
60023A for additional information on media class migration. 
Also refer to Media Type Migration on page  3-29. 

Media type migration occurs only if the Media Class to which 
the media selected for migration belong is associated with both 
the source and destination archives. Archive media class 
association is covered in see 

Low Mark

The low mark parameter is a user-specified percentage. 
VolServ software applies the low mark percentage to the 
archive media-type capacity to calculate a media-type specific 
low mark threshold.

Any integer value between 0 and 100, inclusive, can be 
specified as the low mark percentage. The specified low mark 
percentage cannot be greater than the specified high mark 
percentage.

When the notify action mode option is specified, VolServ 
software generates a message to both the Volume Server 
SysLog Console and archive Console when the number of 
media of the specified media type drops to the calculated low 
mark threshold.

When the migrate action mode option is specified, VolServ 
software marks media for migration out of the archive until the 
number of unmarked media drops to the calculated low mark 
threshold.
