• The error indicates that the volume creation failed as cinder plugin was not able to find the associated Fiber Channel Volume at the backend SAN/NAS Storage .

Resolution

• Try to check the Fiber Channel Connectivity with backend SAN/NAS storage through SAN or Ethernet switch with the storage team assistance.

• If no connectivity or hardware issues are found then try to manually attach a test FC volume from same SAN/NAS storage to the Cinder Host.
