You may not see cdm NFS alarms underneath your robot in USM. If you use the USM alarm view and search for cdm alarms you will see the alarms underneath the nfs device. You can change this behavior with the following
allow_remote_disk_info = no
cdm 5.70 and above
The default behavior is by design so you can trace the root cause of the problem.
1. Within the setup section of the cdm.cfg change the following line "allow_remote_disk_info" to no
2. Clear the niscache by following these instructions linked in TEC1408444
3. Alarms should now show up under the robot in question.
