EMC UIM: Mapping data failed, Failed to associate storage volume

EMC UIM v 4.0 Patch 2

During datastore provisioning EMC UIM created a LUN but did not add it to any of the Storage Groups and failed with “Mapping data failed” error:

EMC UIM Mapping data failed

When I re-run provisioning operation, it failed again:

I successfully re-discovered Vblock to confirm all usernames, passwords were OK and ECOM service is running but still could not provision storage.

I also recently upgraded one VNX array from 5.32.000.5.207 to 5.32.000.5.209  but it was not the issue as the other array on 5.32.000.5.207 exhibited the same errors.

The issue has been resolved as the following:

  1. Restarted Management Server on both VNX’es;
  2. Decommissioned half-provisioned LUN;
  3. Re-provisioned LUNs again.

Hope this will help.
