Reasons why this is desirable:
Oracle's docs claim you need a DHCP server, and to run "mDNS", to install over the network. Either you deal with that mess, or you have to install from DVD.
THIS IS NOT TRUE!
You can successfully use sparc "Wanboot" methodology. No DHCP or mDNS
required. Just remember to update your "network-boot-arguments" string,
along the lines of
file=http://188.8.131.52:5555/cgi-bin/wanboot-cgi(basically, it needs to match whatever the "root_server" line from the wanboot.conf file says)
Now, if you WANT to muck around with DHCP servers, and/or you want to use Solaris 11's "installadm create-client" stuff, more power to you. But if on the other hand, you'd rather just update the openboot network-boot-arguments setting on each server, then it's good to know you still can do that sort of thing.
It's interesting to know that, if you use "boot net", rather than "boot net - install", it will give you a mini-menu on whether you want a shell prompt, or to install Solaris, and also will ask you about disk usage, etc. So, you can also avoid setting up a "system profile" this way, also.
Since I already had the solaris 11 x86 machine, I only had to do 3 steps of pre-install configuration, to install on sparc over the network:
- x86-srv# installadm create-service -a sparc
- (on sparc) ok setenv network-boot-arguments (...host-ip,hostname,router-ip,subnet-mask,file...)
- (on sparc) ok boot net
Do note that the "create-service" subcommand, by default, downloads the
full solaris install files from oracle. There is no need to download the
If you have already done so, however, you may reference it with
installadm create-service -s /path/to.iso
(I think. Havent tested it)
Next, it enables tftp, pointing to /etc/netboot
Next, it lofs mounts the above dir, to /etc/netboot/solaris11-sparc, AND /etc/netboot/default-sparc
Next, it creates two almost identical "system.conf" files under /var/ai/service. One under subdir "default-sparc", and one under "solaris11-sparc". It then lofs-mounts those files specifically, to /etc/netboot/(THATNAME)/system.conf
