Persistent location VMWARE_DATA_DIR write access problem

I want to save some properties file to a persistent location . as per the release documents of 6.0 VMWARE_DATA_DIR can be used for the purpose.

Normally VMWARE_DATA_DIR maps to "/storage"

When i used VMWARE_DATA_DIR for saving  my data, i was not able to write.

But when I manually change the access permissions, I succeeded.

Is there any way to write the file to this "VMWARE_DATA_DIR" location. or any way to change the access permissions.

PS: when i checked the permission it says write permission only for root user. but i logged in as administrator@vsphere.local
