Reach a State to Install a Fresh OS (Oracle ILOM CLI)

Language:

If you do not plan to use the preinstalled OS, use this procedure to prevent the server from booting from the preinstalled OS. You can perform this alternative procedure after reading Step 5 in Configure the Preinstalled OS.

Prepare the appropriate boot media according to your installation method.
There are many methods by which you can install the OS. For example, you can boot and install the OS from DVD media or from another server on the network.

For more information about the methods, refer to Installing Oracle Solaris 11 Systems, comparing installation options at:

http://www.oracle.com/goto/solaris11/docs
From Oracle ILOM, set the OpenBoot auto-boot? parameter to false.
```
-> set /HOST/bootmode script="setenv auto-boot? false"
```
This setting prevents the server from booting from the preinstalled OS. When you use bootmode, the change applies only to a single boot and expires in 10 minutes if the power on the host is not reset.
When you are ready to initiate the OS installation, reset the host.
```
-> reset /System
Are you sure you want to reset /System (y/n)? y
Performing reset on /System
```
Note - In Oracle ILOM 3.1, the name space for /SYS was replaced with /System. You can use the legacy name in command at any time, but to expose the legacy name in the output, you must enable it by typing -> set /SP/cli legacy_targets=enabled. For more information, see the latest Oracle ILOM documentation.
Switch communication to the server host.
```
-> start /HOST/console
Are you sure you want to start /HOST/console (y/n)? y
Serial console started. To stop, type #.
```
The server might take several minutes to complete POST. Then the OpenBoot prompt (ok) is displayed.

Boot from the appropriate boot media for your installation method.
