dns_domain is the Domain Name System (DNS) domain name.
If you use this optional parameter, you do not need a fully qualified domain name in the
netboot server URL. You need only the server's host name.
3. Set up the boot environment:
set-defaults
setenv ONTAP_NG true
setenv ntap.rlm.gdb 1
setenv ntap.init.usebootp false
setenv ntap.mgwd.autoconf.disable true
Depending on N6xxx or N7xxx, set it to e0c for now. You can set it back to e1a later:
setenv ntap.bsdportname e0f
setenv ntap.bsdportname e0c
"a New variable for BR nay be needed."
setenv ntap.givebsdmgmtport true #before installing build
setenv ntap.givebsdmgmtport false #after installing build
"FOR 10-MODE"
setenv ntap.init.boot_clustered true
ifconfig e0c -addr=10.10.123.??? -mask=255.255.255.0 -gw=10.10.123.1
ping 10.10.123.45
4. Netboot from the loader prompt:
netboot http://10.10.123.45/home/bootimage/kernel
5. Enter the NFS root path:
10.10.123.45/vol/home/web/bootimage/rootfs.img
The NFS root path is the IP address of an NFS server followed by the export path.
6. Press Ctrl+C to display the Boot menu.
7. Select Software Install (option 7).
8. Enter the URL to install the image:
http://10.10.123.45/bootimage/image.tgz

Update example
The test environment was composed of two N6070 storage systems, each with a designated
EXN4000 shelf. An upgrade is performed from DOT 7.3.7. If a clean installation is required,
DOT 8.1 7-mode also supports the netboot process.
First, review the current system configuration by using the sysconfig -a command. The
output is displayed in Example 21-4.
Example 21-4 sysconfig command
