Can you please clarify your requirement?
1.do you need datastore utilization report along with parent host name?
2.What version of VROPS do you have
1. I need datastore utilization report with parent vCenter name, Host name is optional. VCenter name would help me to run scripts against all the datastores in the respective vCenter
2. Current vRops version is 220.127.116.11
This is a yes and no answer
The yes is there is a parent vcenter property for each datastore.
The no is dependent on how you named your vcenter display name when you set up the adapter. If you just put in the name of the vcenter then you are fine. If like me you put in some other descriptive text then you will need to strip that out for your script as the parent vcenter is the display name of the adapter not the vcenter name. At least in 7.5 anyway
