ERROR_LIBRARY_OFFLINE

An offline-library record cannot execute changer operations

The RSM database includes an offline library for media that is known to the system but not currently inside an online robotic library. It is a bookkeeping location, not a changer with slots, drives or an insert/eject port. Inventory, inject, eject and similar library-control requests therefore cannot be executed against it even though the library GUID itself may be valid.

Select the actual online library into which the media will be inserted or from which it will be ejected. If the caller obtained the library from the medium object, treat the offline value as a signal to create or service an operator request rather than to call a changer API. Confirm the target library is present and enabled before resubmitting.

What to inspect

  • Distinguish a valid offline-library GUID from an invalid library GUID.
  • Choose an attached online library with the required media type.
  • Use an operator request to move offline media into that library.
