Managing the storage system by using the boot menu

You can use the boot menu to correct configuration problems, reset the root password, initialize disks, reset system configuration, and restore system configuration information back to the boot device.

1. Reboot the system to access the boot menu by entering the following command at the system prompt:
   reboot

   The storage system begins the reboot process.

2. During the reboot process, press Ctrl-C to display the boot menu when prompted to do so.

   The storage system 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)?

3. Select one of the following options by entering the corresponding number:

   To...	Select...
   Continue to boot the storage system in normal mode	1) Normal Boot
   Troubleshoot and repair configuration problems	2) Boot without /etc/rc This menu option causes the storage system to do the following: Use only default options settings Disregard all options settings you specified in the /etc/rc file Disable some services, such as syslog
   Change the password of the storage system	3) Change Password
   Initialize all the disks and create a root FlexVol volume	4) Clean configuration and initialize all disks Attention: This menu option erases all data on the disks and resets your system configuration to the factory default settings. If you need to preserve existing configuration values that are used for system setup (such as your system IP address, gateway addresses, and DNS server addresses), you should make a note of the values before selecting this menu option. You can find your current setup settings by using the setup command at the system prompt. This menu option reboots the storage system before initializing the disks. After the initialization procedure finishes, the setup script starts and prompts you for configuration information. For information about setting up the storage system, see the Data ONTAP Software Setup Guide for 7-Mode. Data ONTAP 8.0 and later releases do not allow you to create a new traditional root volume from the boot menu. However, preexisting traditional root volumes are still supported. For a V-Series system that has a disk shelf, this menu option initializes only the disks on the disk shelf, not the array LUNs. For a V-Series system that does not have a disk shelf, this menu option initializes the root volume on the storage array.
   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 root FlexVol volume to the boot device, such as a PC CompactFlash card	6) Update flash from backup config Data ONTAP stores some system configuration information on the boot device. When the storage system reboots, the information on the boot device is automatically backed up onto the root FlexVol volume. If the boot device becomes corrupted or needs to be replaced, you use this menu option to restore the configuration information from the root FlexVol volume back to the boot device.
   Install new software on a V-Series system	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 your system. This menu option is only for installing a newer version of Data ONTAP software on a V-Series system that has no root volume installed. Do not use this menu option to upgrade the Data ONTAP software on either a FAS system or a V-Series system.
   Reboot the storage system	8) Reboot node
