Dell Unity™ Family VNX® Series Data Import to Unity All Flash or Hybrid, or UnityVSA™ System User Guide

Start a CIFS-only VDM import session

The import session is automatically started after creation in the Unisphere UI.

For UEMCLI or REST, the UEMCLI command and REST operation of start are shared with the same command and operation of resume to align with the behavior of block import and replication. You can only start an import session when it is in the Initialized state. If the import start fails, the import state is kept as Initial Copy with a Minor failure health state and the health details are set to The migration session failed to provision target resource. At this time, you can fix the problem by getting detailed information from the job and tasks and then resume the import session.

The start of an import session is an asynchronous operation by default and always returns a success after creating a backend job to run the initial copy. Before the start of the import, a pre-check is done.

In the event of an SP reboot, affected import sessions fail over to the peer SP. In the event of a system reboot, import sessions pause and automatically resume when the system returns.
