No LUN latency charts on Hitachi arrays

Overview

LUN latency chart for Hitachi Storage Arrays (HDS) is flat (all showing in zeroes).

Environment

SRM Orion 6.2.x

Cause 

This metric is not supported by Hitachi SMI-S provider.

Resolution

1. Connect to the Hitachi SMI-S provider using the CIM browser. 
2. Get the instances for class - HITACHI_BlockStatisticalDataStorageVolume.
3. Get the properties for one of the instances and check the property 'IOTimeCounter' (if it exists). This property is used to calculate altency information. If this is missing or if it contains zero or NULL, then we can confirm that the SMI-S provider does not give us this information.
