Solved: New OCUM 9.4 error - "Unable to add data source" error when trying to add cluster

KUBER_KATANA1 · ‎2018-08-01

Hi,

Installed latest OCUM 9.4. When trying to add NetApp cluster it is giving me the following error:

"Unable to add data source, which can be caused by reaching the max number of EMS notification destinations in the data source."

How do I increase the max number of EMS notification destinations count on the Cluster?

Cluster ONTAP version 9.3P1.

Thanks in advance.

There are two reasons why you could have this failure. 1) is as message says that you have too many UM instances monitoring the same cluster which makes the registration quota run out; 2) it could be that the UM instance clock is ahead of the cluster time. 2) is what we found out after we released 9.4. If you think 1) is not likely to happen, can you please check if the two clocks (UM and cluster) are in sync?

Had issue with the NTP server used by OCUM. Fixing it and providing right time to OCUM resolved the issue.

Thanks for your help, Ruijuan.

Glad to know that it helped. We enchanced the error message in OCUM 9.5 (to be released in Nov).
