When trying to add a new Disk to the Cluster probe configuration for CDM probe the following error message pops up:
"Request Error - communication error"
this type of error has been seen when old drives are still in the cdm.cfg that do not longer exist.
UIM 8.51, CDM v6.01, Cluster v4.42 & Robot v7.91
Remove the monitoring configs and re-apply them to the Cluster
