There is a known bug with RCU 2.1 and VMware View imports: https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb53664
View 4 support with RCU 2.1 is experimental but there is a workaround for the issue you are seeing. In case you do not have access to now.netapp.com I've posted the description below:
Symptoms
When running an RCU job that automatically imports the VMs into VMWare View, the task in vCenter never completes. It remains in "In Progress" status. In addition, the RCU service crashes. Despite this, the VMs are actually imported into VMWare View.
VMWare View import process from RCU does not complete successfully.
Cause of this problem
This is a bug in the RCU code that imports the data into VMWare View.
Solution
Workaround:
1. Restart the RCU service with the following commands:
net stop netappVIPluginService
net start netappVIPluginService
2. Cancel the task in vCenter using the VI Client.
