Description

This article describes the procedure to install a new bootable image on the Boot Device in Data ONTAP 8.1.x (and later).

Warning: This article is used to Netboot clustered Data ONTAP. This procedure is not used to NetBoot Data ONTAP 7G or Data ONTAP 7-Mode. Specifically, the env setting in step 3 'setenv bootarg.init.boot_clustered true' should not be run on a Data ONTAP 7-Mode system.

Data ONTAP 8.x uses the netboot procedure to boot a version of Data ONTAP that is on a remote web server. The netboot procedure will allow a controller to boot to the Data ONTAP boot menu. From the Data ONTAP boot menu, the install procedure can be used to install new software to the Boot Device (CF card). The controller then requires information to be restored from the root volume to the boot device for normal boot to continue.

After the boot device information has been restored, a normal boot can occur using the new Data ONTAP image that has been installed on the boot device.

Attention: This procedure is disruptive, even when using it with a system in an HA pair, because an immediate giveback and re-takeover will occur during the procedure.

Note: If installing a version of Data ONTAP 8.2.x, reboot the node (with or without takeover) after booting normally to ensure the netboot and installation process has completed.
