CIM Query Language support

Question asked by Igor Golikov on Jan 30, 2015

Hello,

 

I've checked several Hitachi storages in our lab and in SNIA lab and find out that all of them support CQL (CIM Query Language  - DMTF DSP0202).

Supported communication mechanism can be obtained from HITACHI_CIMXMLCommunicationMechanism instance

FunctionalProfileDescriptions[]  :  Basic Read, Basic Write, Instance Manipulation, Association Traversal, Query Execution,

 

But only "Basic Query" feature is suppored. CIM_QueryCapabilities instance:

================================

InstanceID  :  10.6.153.41.QueryCapabilities

ElementName  :  Query Capabilities

CQLFeatures[]  :  2,

Caption  :  Query Capabilities

Description  :  Query Capabilities

XPathFeatures  :  0

Generation  :  0

 

I tried to execute several queries  - some of them works , others don't. Even samples from DMTF DSP0202 don't work.

 

SELECT * FROM HITACHI_ThinProvisioningPool - works

SELECT * FROM CIM_StoragePool  - doesn't, CIM_ERR_INVALID_QUERY

SELECT * FROM HITACHI_ThinProvisioningPool WHERE PoolID = 'ThinProvisioningPool.0'    - doesn't, CIM_ERR_INVALID_QUERY

 

Why this queries returns CIM_ERR_INVALID_QUERY, Hitachi SMI-S provider doesn't implement "CIM Query Language" correctly?
