If you use this optional parameter, you do not need a fully qualified domain name in the
netboot server URL. You need the server's host name only.
3. Set up the boot environment, as shown in the following example:
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, as
shown in the following example:
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, as shown in the following example:
netboot http://10.10.123.45/home/bootimage/kernel
5. Enter the NFS root path, as shown in the following example:
10.10.123.45/vol/home/web/bootimage/rootfs.img
The NFS root path is the IP address of an NFS server that is followed by the export path.
6. Press Ctrl+C to display the Boot menu.
7. Select Software Install (option 7).
8. Enter the following URL to install the image:
http://10.10.123.45/bootimage/image.tgz
Tip: The URLs that are shown are examples only. Replace them with the URLs for your
environment.
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 shown in Example 21-4 on page 303.
