Media Manager status code 55
Message: robot number and volume group mismatch
Explanation: A request was made to add or change the volumes in the volume configuration. The robot number and the volume group that is associated with the volume configuration changes are in conflict with the requirements for volume groups. All of the volumes in a volume group are required to have the same residence and that includes having the same robot number.
Recommended Action:
Examine the command output, debug logs, and system logs for a more detailed message on the error.
See "Setting Media Manager debug logging to a higher level" in the NetBackup Logging Reference Guide.
Ensure that the specified robot number and volume group are compatible. If the volumes in the volume group have a given robot number, then the volumes with a different robot number cannot be added to that volume group. The volumes cannot be moved directly from one robotic volume group to another robotic volume group. The intermediate steps (some volume entries are changed and some are not) would cause a conflict with the robot numbers. Choose a different volume group on the request, or let the volume group be selected automatically. The volume group selection depends on the specific interface being used.
