Inventory, Lock, Unlock, Label, & Erase jobs do not run against a Robotic Library and "Ready; No Idle Devices are available" shows in the Job Monitor if a backup job is queued and prompting for a user to insert more media.
Because of changes that have been made to the Backup Exec 10.x and later Version software code, Inventory, Lock, Unlock, Label, & Erase jobs submitted while a job is prompting for media will hang indefinitely in a "Ready; No Idle Devices are available" state in the Job Monitor until the backup job is canceled or is able to resume/complete. The display on the tape hardware will show that the device is idle and ready, even though Backup Exec believes it not to be.
For a loader without a mail slot/bar code reader, the work-around to get a job to resume that requires additional media is as follows:
Please Note: The work-around listed above may not function if the auto loader or robotic library door remains in a lock down state and will not open after the import command is issued.
If a library has a mail slot, the import/export commands can be issued and an initialize can be run on the loader's slots, after the media has been replaced. It is not possible to run a label or erase job if a backup job is prompting for media.
