When coming from old Sun server background (say, V240), T4 represents a challenge. Even booting to DVD is not that transparent and that what is needed if you wish to install Solaris 10 instead of factory pre-installed Solaris 11.

T4 has two level system: service processor(ILOM) -> openboot system.

ILOM is similar to HO ILO and has both web interface and command line interface.  Web interface is easier to work with, but firts you need to set parameters such as IP, netmask and default gateway (if you do not have DHCP) using command line interface. See Setting up Oracle ILOM on Sparc T4 server

In order to be able to send break, to get to OK prompt you need first to set

set send_break_action=break 

when at /HOST

If OS is present, then you can get to open boot prompt using halt command to get to OK prompt.

When at OK prompt you need to issue a standard OBP command

boot cdrom - install

for the installation from the DVD.  Booting of the server takes 10 min or more, so be patient.

[May 28, 2013] Solaris 10 installation on SPARC T4-1 ...

Aug 7, 2012 | OTN Discussion Forums


We have recently purchased SPARC T4-1 server comes with Solaris VM server in built.
I want to install Solaris 10 OS on it. How do I boot from DVD to start the Solaris 10 installation?

I just want to install on the SPARC T4-1 server. I have a DVD drive on the server. I need to boot from Solaris 10 boot DVD.

Currently the SPARC T4-1 is with Solaris 11 and I don't want that. I want to use Solaris 10 on it.

How do you I initiate the fresh Solaris 10 installation on the server?



On T4-1 it's easy...
1. Stop Solaris 11 ( halt or init 0 for example )
2. On Console at ok prompt type boot cdrom

For cdrom install, command sequence is

boot cdrom - install

from OK prompt. Fresh install will overwrite the existing base OS.

Using Logical Domains With the Service Processor - Oracle VM Server for SPARC 2.1 Administration Guide

Reset the logical domain configuration on the next power on to the default shipping configuration by executing this command:

set /HOST/bootmode config=factory-default

You also can select other configurations that have been created with the LogicalDomains Manager (Logical Domains Manager - Oracle VM Server for SPARC 2.1 Administration Guide) using the

ldm add-config

command and stored on the service processor (SP).

The name you specify in the Logical DomainsManager ldm add-config command can be used to select that configuration with the ILOM bootmode command.

For example, assume you stored the configuration with the name ldm-config1.

set /HOST/bootmode config=ldm-config1
