Hi there, 

i try to get some data from the DSM for my two SCv3020.

So i found the Dell Storage Manager REST API Cookbook.

I got the script and got first data..

But when it tries to access the /StorageCenter/ScDiskFolderTier/[InstanceId]/StorageUsage

I get only "HTTP/1.1" 400"

How can i check if the script from dell is wrong?
