Shutdown a 7 node cluster

  • Hi, our server are physically being moved to a new data center. There is a 7 node failover cluster running on these servers. Could anyone please suggest the process to shutdown this cluster group so that when the server comes back up there shouldn't be any problems regarding the cluster failovers. There are 21 instances on 6 of the nodes and one node is passive.

    I came up with the following steps:

    1. Shutdown the Passive Node.

    2. Designate one of the nodes to move all the instances. Lets say node 1.

    3. Move the instances of an active node to node 1 and shut down the active node.

    4. Repeat step 3 for all the active nodes by moving the instances on these nodes to node 1 and shutting them down.

    5. Once all the instances are on node 1 turn off the instances are shut down the node.

    6. Turn off SQL server agent then the SQL server and cluster services.

    alternatively:

    1. Shutdown the Passive Node.

    2. Designate one of the nodes to move all the instances. Lets say node 1.

    3. Move the instances of an active node to node 1 and shut down the active node.

    4. Turn off all the instances on Node 1.

    5. Repeat step 3 and 4 for all the active nodes(moving the instances on these active nodes to Node 1, shutting the active node down and turning off the instances once they are running on Node 1).

    6. Once all the nodes are turned off except for Node 1, turn off node 1.

    Please let me know if I am on the right track or suggest the best process.

    Ok so far

    2. Designate one of the nodes to move all the instances. Lets say node 1.

    3. Move the instances of an active node to node 1 and shut down the active node.

    All of the instances may not be installed across all of the nodes, in fact I'd recommend against.

    5. Once all the instances are on node 1 turn off the instances are shut down the node.

    this is unnecessary

    6. Turn off SQL server agent then the SQL server and cluster services.

    Stopping the sql server instance clustered resource will automatically stop it's agent due to the resource dependency.

    I would

    • Shutdown the Passive Node.
    • stop all clustered roles by offlining each group. You can do this via powershell quite easily
    • shutdown each node in turn
    • relocate servers
    • boot each server
    • when cluster service has started on each node and the cluster has been formed online each of the groups on your chosen node, again very easy using Powershell
