Explanation: A request is made to add or change volumes in the volume configuration, or to issue a robot inventory update request. A specified robot host differs from the robot host for other volumes in the same robot (defined as those volumes having the same robot number). All volumes in the EMM database that have a given robot number (for instance, 0) must have the same robot host name.
Examine command output, debug logs, and system logs for a more detailed message on the error.
Specify the robot host in the device configuration to be the same case-sensitive host name on all hosts where the robot is configured. Re-issue the request. As an alternative, use move-by-volume group to move all volumes logically from a robotic volume group to stand-alone and then back into the robot. Specify the robot host as the host name that is used in the robot configuration. Then re-issue the request.
