HBA details using winrm

[unnisworld]

I am trying to query for HBA attributes through winrm using the
following command,

winrm e wmi/root/MSFC_FCAdapterHBAAttributes

The error message that i am getting is : The WS-Management service
cannot process the request. The service cannot find the resource
identified by the resource URI and selectors.

I am able to query for cim classes like - wmi/root/cimv2/
Win32_ComputerSystem

This is a Windows 2003 machine and fcinfo tool is installed on the
machine. I am able to see the HBA details through WMI Object browser
tool.

Am I using the correct URI ?
