6. If you have a stand-alone system, exit Maintenance mode by entering the
following command on the target node:
halt
7. After the target node displays the boot prompt, enter the following command
to boot the operating system:
boot_ontap
For a system in an HA pair , this command puts the node in Waiting for
Giveback state.
8. Proceed depending on whether the system is in an HA pair :
If the controller module is...

Stand-alone
Performing a final takeover and giveback from the target node
To ensure that the disk reassignment is successful, you must perform a final
takeover and giveback from the target node.
About this task
These steps must be taken regardless of the version of Data ONTAP you are using.
It is important that you apply the commands in these steps on the correct system:
v The impaired node is the node on which you are performing maintenance.
v The healthy node is the HA partner of the impaired node.
Procedure
1. Take over the partner node by entering the following command from the target
node's console:
cf takeover
2. Return control to the partner node by entering the following command from
the target node's console:
cf giveback
A successful giveback ends with a message on the partner node indicating
successful giveback.
Note: If Waiting for Giveback is not displayed prior to giveback, reboot the
controller module. If this continues, contact technical support.
