NetApp StorageGRID SG6000 Manual page 166

The node uses the DNS server settings specified on this page to reconnect to the KMS, allowing data on
the node to be decrypted.
5. After node data is decrypted, reboot the node. From the StorageGRID Appliance Installer, select
Advanced > Reboot Controller, and then select one of these options:
◦ Select Reboot into StorageGRID to reboot the controller with the node rejoining the grid. Select this
option if you are done working in maintenance mode and are ready to return the node to normal
operation.
◦ Select Reboot into Maintenance Mode to reboot the controller with the node remaining in
maintenance mode. (This option is available only when the controller is in maintenance mode.) Select
this option if there are additional maintenance operations you need to perform on the node before
rejoining the grid.
When the node reboots and rejoins the grid, it uses the system-wide DNS servers listed
in the Grid Manager. After rejoining the grid, the appliance will no longer use the
temporary DNS servers specified in the StorageGRID Appliance Installer while the
appliance was in maintenance mode.
It can take up to 20 minutes for the appliance to reboot and rejoin the grid. To confirm that the reboot is
complete and that the node has rejoined the grid, go back to the Grid Manager. The NODES page
should display a normal status (no icon) for the appliance node, indicating that no alerts are active and
the node is connected to the grid.
