The directory /etc/software hosts installable ONTAP releases (see Figure 21-1). The
installation images were copied from a Windows client by using the administrative share
\\filer_ip\c$.

Starting with DOT 8, software images end with .zip and are no longer .exe or .tar files. The
software command must be used to install or upgrade DOT 8 versions. At the time of this
writing, only DOT 8.1 7-mode was available. Therefore, all tasks were performed by using this
software version. When the system reboots, press CTRL+C to access the first boot menu.
Use the software command. Complete the following steps:
1. Run the software get command to obtain the Data ONTAP code from an http server. A
simple freeware http server is sufficient for smaller environments.
2. Run the software list command to verify that the code is downloaded correctly.
3. Run the software install command with your selected code level.
4. Run the download command.
5. Run the reboot command to finalize your upgrade.
Requirement: The boot loader must be upgraded. Otherwise, Data ONTAP 8 does not
load and the previously installed version continues to boot.
Upgrade the boot loader of the system by using the update_flash command, as shown in
Figure 21-2 on page 305.
Attention: Ensure that all firmware is up to date. If you are experiencing long boot times,
you can disable the auto update of disk firmware before you download Data ONTAP by
using the following command:
options raid.background_disk_fw_update.enable off
