To reduce the SMI-S provider workload and therefore improve performance, it is recommended to remove some EMC systems from the SMI-S provider. This action can be performed with the remsys command.


The “remsys” command requires SMI-S 4.3.x or later.


  1. Log into the server where the SMI-S Provider is installed.
  2. Open a command prompt.
  3. Change directory to: C:\Program Files\EMC\ECIM\ECOM\bin (where C:\ is the ECIM install drive).
  4. Type TestSmiProvider to launch the utility.
  5. Login with an Admin username and password.
  6. Type “ein” to enumerate instance names.
  7. Type the class value “Clar_StorageSystem”. The utility should produce output similar to the following:

    ++++ Testing EnumerationInstanceNames: Clar_StorageSystem ++++
    Instance 0:
    Clar_StorageSystem.CreationClassName="Clar_StorageSystem",Name="CLARiiON CKx000xxxxxxxxxx"
    Instance 1:
    Clar_StorageSystem.CreationClassName="Clar_StorageSystem",Name="CLARiiON+ CKx000xxxxxxxxxx"

  8. Copy the entire path of the array that you wish to remove.
    Example: Clar_StorageSystem.CreationClassName="Clar_StorageSystem",Name="CLARiiON CKx000xxxxxxxxxx"
  9. Append the EMC CLARiiON path to WBEM server path.
    Example: //"Clar_StorageSystem",Name="CLARiiON+CKx000xxxxxxxxxx"
  10. Type “remsys”.
  11. Type “Y” to confirm.
  12. Paste the new object path at the Systems ObjectPath prompt.
  13. Type “Y” to confirm.

The EMC CLARiiON array should now be removed. You can run a “dv” command to verify the system has actually been removed.
