    Hola Davi!

    it should be:
    svctask stopsystem -node <node name>


    From:
    https://www.ibm.com/docs/en/sanvolumecontroller/8.5.x?topic=commands-svctask-stopsystem


    Prerequisites are also mentioned there.

    Hello Luis, i've tried but got error CMMVC5798E,  The action failed because the node is offline.
    i've checked MAP 5350: Powering off a node
    but as the sv2 hasn't physical buttons, I didn't find the solution

    Hello Davide, that means that the node is already offline from the cluster point of view. 
    You can check the state of all nodes with lsnode node command. This will show you all nodes in the cluster and their state.
    If you see the spare node state as offline in the output, that means it is either turned off or in service state(though I believe it will have state service), if it is turned off you can disconnect the power cables from it and move it. Also the indicator LEDs on the node canister would be in off state.
    Just double check that you are physically working with the correct node. 
    Some additional information:
    https://www.ibm.com/docs/en/sanvolumecontroller/8.3.x?topic=indicators-node-canister-rear-panel

    If node is in service state:
    1. Please ssh to the service IP of the node, 
    2. double check that you are on the node you wish to work with (lsservicenodes command)
    3. run command: 

    satask stopnode -poweroff <node_panel_name>

    You can find more details here:  https://www.ibm.com/docs/en/sanvolumecontroller/8.3.x?topic=commands-stopnode

    Links are for 8.3 code level, but you can double check the details and commands by choosing your code level on the left side menu. Also as I aware there were no changes in those commands.

    Best Regards, Denis.
