3.2.1.4 List of Tasks Currently Executed on the Server
Library Requests
When applications make a library request, the server places these requests in a queue and processes them as resources become available. For example, a request to mount a tape in a library results in a mount work queue item, which might wait until a drive is available.
Operator Requests
The server generates operator requests in the following situations:
Media is required to be moved online because an application has initiated a mount request for media that is offline.
There are no available media online in the specified application media pool or in the appropriate free media pool when an application requests media allocation. The operator provides new media or available media that is offline to satisfy the request.
A device fails and requires service.
A drive needs to be cleaned, and there is no usable cleaner cartridge available in the library unit.
