Insertion of logical volumes into a library using a media manager

Disclosed is a system to allow improved logical volume insertion rate into a database that is attached to a media manager and physical library. Volume ranges are entered into the physical library via a user interface. The logical volumes are discovered by the media manager and stored into it's database as being discovered. We will call this discovered state the WAIT category. Before they can be used, they must be "inserted", which is a process changing the category of the volumes from WAIT to insert. Normally this process involves taking each volume and changing it's category, which is a long and tedious process. The following diagram shows how this method was performed.

Using the old method, each volume moved involved a call to the database. This could potentially involve 1 million calls and not uncommon to have thousands which could take hours to accomplish. To get around this, the normal interface calls to move a volume can be bypassed in favor of an IEEE compliant query that moves all volumes that are in the WAIT category to the insert category. The following diagram shows the new method.

This allows all volumes to be changed in one database call, saving hours of time if there are many volumes...
