Managing a node by using the boot menu

You can use the boot menu to correct configuration problems of a node, reset the admin password, initialize disks, reset node configuration, and restore node configuration information back to the boot device.


  1. Reboot the node to access the boot menu by using the system node reboot command at the system prompt.
    The node begins the reboot process.
  2. During the reboot process, press Ctrl-C to display the boot menu when prompted to do so.
    The node displays the following options for the boot menu:
    (1) Normal Boot.
    (2) Boot without /etc/rc.
    (3) Change password.
    (4) Clean configuration and initialize all disks.
    (5) Maintenance mode boot.
    (6) Update flash from backup config.
    (7) Install new software first.
    (8) Reboot node.
    Selection (1-8)?
    Note: Boot menu option (2) Boot without /etc/rc is obsolete and takes no effect on the system.
  3. Select one of the following options by entering the corresponding number:
    To... Select...
    Continue to boot the node in normal mode 1) Normal Boot
    Change the password of the node, which is also the "admin" account password 3) Change Password
    Initialize the node's disks and create a root volume for the node 4) Clean configuration and initialize all disks
    Attention: This menu option erases all data on the disks of the node and resets your node configuration to the factory default settings.

    You select this menu option after the node has unjoined the cluster and before it rejoins another cluster. This menu option reboots the node before initializing the disks.

    For a node that uses array, this menu option initializes only the disks on the disk shelf, not the array LUNs. For a node that does not have a disk shelf, this menu option initializes the root volume on the storage array.

    If the node you want to initialize has disks that are partitioned for root-data partitioning, the disks must be unpartitioned before the node can be initialized.

    Perform aggregate and disk maintenance operations and obtain detailed aggregate and disk information. 5) Maintenance mode boot

    You exit Maintenance mode by using the halt command.

    Restore the configuration information from the node's root volume to the boot device, such as a PC CompactFlash card 6) Update flash from backup config

    Data ONTAP stores some node configuration information on the boot device. When the node reboots, the information on the boot device is automatically backed up onto the node's root volume. If the boot device becomes corrupted or needs to be replaced, you use this menu option to restore the configuration information from the node's root volume back to the boot device.

    Install new software on the node 7) Install new software first

    If the Data ONTAP software on the boot device does not include support for the storage array that you want to use for the root volume, you can use this menu option to obtain a version of the software that supports your storage array and install it on the node.

    This menu option is only for installing a newer version of Data ONTAP software on a node that has no root volume installed. Do not use this menu option to upgrade Data ONTAP.

    Reboot the node 8) Reboot node
