Open the alerts and on the Alert Context tab you will see information related to the "StorageObjectsDiscovery.DS.ps1".
Most cases that I have seen involve 4 alerts. The first one in the Alert Context Data says "Storage Discovery: started." The second alert says "Storage Discovery: Got VMMServer. Module imported." Third alert says "Missing Value in Property Id: {78FCB9D8-AFF4-785C-CAC3-1C9B8BAAA561}." And the fourth and last alert says "Storage Discovery: Complete!".
These then repeat every 6 hours.
You can either ignore these and delete them as often as you want. Or you can set an override by right-clicking on the alert and select Overrides -> Override the Rule -> For all objects of class: Health Service. Check the Enabled parameter and change the override value to False. Save to a new management pack. That will stop you from seeing the alerts for now.
When the new version of the MP Suite comes out, these annoying alerts are supposed to be removed.
