Explanation: When a process performed a media-related operation, it encountered an empty or an incorrectly formatted media identifier. Or a media ID that was passed to it cannot be operated on as requested.
Examine command output, debug logs, and system logs for a more detailed message on the error.
Ensure that the specified media IDs contain valid characters only: alphanumeric characters, the period (.), the plus sign (+), and the underscore (_). A hyphen (-) is also a valid character when not the first character in the media ID.
If media are specified to be ejected from a library, ensure the following: they exist in the EMM database and are associated with the correct robot number.
Ensure that the media ID is from 1 to 6 characters in length.
If the operation is an inventory request for an ACS robot, use the robtest utility to verify the following: the ACS interface returns cleaning media IDs both in the query volume list and in the query cleaning volume list.
