Won’t work. Once FLI is started, all access from host must go via NetApp. Accessing source directly will result in data corruption.
At the end it is near to impossible to move to different storage brand without downtime. Ideally you use host based volume manager, but it is probably out of question in the case. So you can only try to keep downtime as short as possible.

Hi All,
We have been using Foreign LUN Import to migrate 3rd party storage systems into CDOT. So far, we have been shutting down servers to perform the cutover.
However we are now due to migrate some multiple node SQL clusters and looking at the possibility of using windows failover cluster manager to make these migrations non-disruptive.
i.e. Failover node 1 resources to node 2 FLI node 1 LUN’s & re-zone Failover node 2 resources to node 1 FLI node 2 LUN’s & re-zone
We are worried that if we fail over each windows node, migrate it’s disks using FLI and change the zoning. When we failover the next node which still has direct access to the 3rd party storage, any writes made will not go through the LUN import relationship on CDOT and potentially cause corruption.
Can anyone offer any advice on this?
Many Thanks, Chris.
