Host DPI Parameter Object Class Code
To access ‘Device’ parameters, use the DPI Parameter Object (Class Code
0x93).
Important: The Host DPI Parameter Object is supported only when the
adapter is used with a PowerFlex 750-Series drive.

The number of instances depends on the number of parameters in the device.
The total number of parameters can be read in Instance 0, Attribute 0.
