DescribeWorkingStorage
Returns information about the working storage of a gateway. This operation is only supported in the stored volumes gateway type. This operation is deprecated in cached volumes API version (20120630). Use DescribeUploadBuffer instead.
Note
Working storage is also referred to as upload buffer. You can also use the DescribeUploadBuffer operation to add upload buffer to a stored volume gateway.
The response includes disk IDs that are configured as working storage, and it includes the amount of working storage allocated and used.
