You can use the boot menu to correct configuration problems on a node, reset the admin password, initialize disks, reset the node configuration, and restore the node configuration information back to the boot device.
(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. (9) Configure Advanced Drive Partitioning Selection (1-9)?
| To... | Select... |
|---|---|
| Continue to boot the node in normal mode | 1) Normal Boot |
Change the password of the node, which is also the adminaccount 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.
Only select this menu item after the node has been removed from a cluster (unjoined) and is not joined to another cluster, see Removing nodes from the cluster. For a node with internal or external disk shelves, the root volume on the internal disks is initialized. If there are no internal disk shelves, then the root volume on the external disks is initialized. For a system running FlexArray Virtualization with internal or external disk shelves, the array LUNs are not initialized. Any native disks on either internal or external shelves are initialized. For a system running FlexArray Virtualization with only array LUNS and no internal or external disk shelves, the root volume on the storage array LUNS are initialized, see the FlexArray® Virtualization Installation Requirements and Reference guide. 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, see 9) Configure Advanced Drive Partitioning and the Disks and Aggregates Power Guide. |
| 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
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 must 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 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 ONTAP software on a node that has no root volume installed. Do not use this menu option to upgrade ONTAP. |
| Reboot the node | 8) Reboot node |
| Unpartition all disks and remove their ownership information or clean the configuration and initialize the system with whole or partitioned disks | 9) Configure Advanced Drive Partitioning Beginning with ONTAP 9.2, the Advanced Drive Partitioning option provides additional management features for disks that are configured for root-data or root-data-data partitioning. The following options are available from Boot Option 9:
(9a) Unpartition all disks and remove their ownership information. (9b) Clean configuration and initialize system with partitioned disks. (9c) Clean configuration and initialize system with whole disks. (9d) Reboot the node. (9e) Return to main boot menu. |
