Explanation: A request was made to add or change volumes in the volume configuration but the volume number was at its allowable limit. The limit is based on the number of volumes that is allowed in a particular type of robot.
Examine command output, debug logs, and system logs for a more detailed message on the error.
Check to see if volumes are defined in the EMM database. They may be defined in the EMM database, which is associated with a slot number zero that may not exist in the robot. Run a robot inventory Show contents of robot report and observe the starting slot number. If the starting slot number is one and a volume is defined in the robot at slot zero, delete the volume entry. Or move it to stand-alone so that the remaining available media slots can be used.
