  • ONTAP 9
  • SnapMirror

Answer

No.

  • CSM session is used for data communication, but the "csm.createSessionFailed" message indicates session creation failure before data tranfer.
  • Even if CSM session fails during data transfer,  SnapMirror does not cause data inconsistency.
    • SnapMirror checks the checksum of the transferred data.
    • SnapMirror maintains information about the blocks being transferred and the blocks being sent.
