Query regarding WMI Win32 Interface

[Ravindranatha K]

Hello Sir,

I am an Hewlett Packard, India employee, i wanted the
following information using Win32 WMI Provide.
I need the following fields using WMI Win32 interface:

1. SCSI HBA Driver Revision
2. SCSI HBA Speed
3. SCSI BUS Speed
4. SCSI BUS Bandwidth
(No of drives that can be connected to BUS)
5. SCSI Tape Driver Revision
6. SCSI Tape Drive Negotiated Transfer Rate

Actually i saw these fields in the following WIN32
provider classes:

class CIM_Controller - Win32_SCSIController:
-members: MaxNumberControlled, MaxTransferRate

class CIM_DeviceConnection - Win32_SCSIControllerDevice:
-members: NegotiatedSpeed, NegotiatedDataWidth

CIM_SCSIInterface:
-members: NegotiatedDataWidth, NegotiatedSpeed,

I tried to get the above fields using Win32 Provider.
But they are always empty.
Can you please tell me that, is there any way to populate
these values OR is there any other way to get all the six
fields specified above.

Thanks in advance

Ravindra
