Sun Solaris 10 Network Install (LAN)

My environment:
Sun Blade T6320, Platform Group: sun4v
Install Server: x86 with Sun Solaris 10
Install Server and Client (Target system for installation) sit on the same subnet

Sun Official Documentation:

Solaris 10 6/06 Installation Guide: Network-Based Installations

http://docs.sun.com/app/docs/doc/819-5776

Steps taken applicable to my environment:

1. Create install server

# mkdir -p install_dir_path ;Create a directory to save the image
# cd /cdrom/sol_10_1008_sparc/Solaris_10/Tools  ;the keyword here is Tools folder
# ./setup_install_server install_dir_path  ;execute the script, it might take some time here

2. Modify ur hosts file (/etc/inet/hosts)at your install server.
Example, if your new client (target system for installation) is named
hostname: newsol10
IP Address: 10.0.0.123

Your hosts file (/etc/inet/hosts) should have the following entry
10.0.0.123 newsol10

3. Create a file with the following path and name -- /etc/ethers and this file should have the following entry
0:14:fc:xx:yy:zz newsol10

You can obtain your machine MAC address by looking at the information while it is booting as below:

Sun Blade T6320 Server Module, No Keyboard

OpenBoot 4.27.10, 32640 MB memory available, Serial #xxxxyyyy.
Ethernet address 0:14:4f:xx:yy:zz, Host ID: xxxxyyyy.

or

from ILOM, type show /HOST

-> show /HOST

4. Add system to be installed using add_install_client

# cd /install_dir_path/Solaris_10/Tools
# ./add_install_client newsol10 sun4v

bash-3.00# ./add_install_client newsol10 sun4v
saving original /etc/dfs/dfstab in /etc/dfs/dfstab.orig
Adding "share -F nfs -o ro,anon=0 /solaris10sparc" to /etc/dfs/dfstab
making /tftpboot
enabling tftp in /etc/inetd.conf
Converting /etc/inetd.conf
enabling network/rarp service
enabling network/rpc/bootparams service
updating /etc/bootparams
copying boot file to /tftpboot/inetboot.SUN4V.Solaris_10-1

5. Boot your client into OBP session (OK prompt) and at the ok prompt, type
ok boot net - nowin    ;into console mode installation

* I encoutered "timed out waiting for tftp reply" after typing the command above,
i not sure why but after i restart the install server as well as my client, the error goes away.

Result from boot net - nowin
