Issue

  • Disks are not discovered when performing a Refresh Disks on a Plug-In for Windows host
  • The SCW_<JOB>.log for the resource discovery job reports the below error

Information SDW PID=[5152] TID=[22320] GetHostFileSystem: Return '0' lun fileSystems
Error SDW PID=[5152] TID=[22320] Failed to get resource object graphs using SMAPI. Error code: 0. Details: Failed to enumerate the disks. 
Verbose SDW PID=[5152] TID=[22320] --SmapiToStorageResolver::GetResourceObjectGraphs

Error SDW PID=[5152] TID=[22320] Error: The resource graph is null/empty

  • Alternatively, you may see the following sequence and error:

Verbose SDW PID=[3652] TID=[2096] query: select * from MSFT_Volume Where FileSystem = 'NTFS'
Verbose SDW PID=[3652] TID=[2096] scope: \\SRV00123\root\Microsoft\Windows\Storage

Verbose SDW PID=[3652] TID=[2096] INFO: Config setting for whether to do have WMI query time out is not found. Using the default value of False
Verbose SDW PID=[3652] TID=[2096] INFO: WMI query time out = False
Verbose SDW PID=[3652] TID=[2096] --ConfigManager::GetConfigSettingIs_Wmi_Timeout_Set

Error SDW PID=[3652] TID=[2096] Error: Failed to get Windows volumes

  • Thirdly, WMI may not be responding properly causing the following outputs in addition to the error above:
