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.
