Enable or Disable Automatic Booting (Oracle Solaris)

Language:

Use this procedure to configure OpenBoot so that a host reset or power on either attempts to boot automatically, or not, when Oracle Solaris is running in the host. This change does not affect the reboot command. If you issue the reboot command, or if the Oracle Solaris OS panics and reboots, the host will continue the boot process.

Note - To enable automatic booting of the OS, the OpenBoot auto-boot? variable must be set to true and the Oracle ILOM auto-boot property must be enabled. You can change the auto-boot? variable at the Oracle Solaris prompt with the eeprom command or at the OpenBoot prompt with the setenv command. You can change the auto-boot property in Oracle ILOM at /Servers/PDomains/PDomain_n/HOST/domain/control.

You must have the console role (c) and the admin role (a) to complete this task.

Log in to Oracle ILOM.
See Log In to Oracle ILOM (CLI).
Start the host console.
See Start the Host Console.
If necessary, start the host.
See Start a Host.
Set the OpenBoot auto-boot? variable.
- true – (Default) The host automatically attempts to boot from the devices specified in boot-device if you configured the boot-device variable and you enabled the Oracle ILOM auto-boot property.
- false – The host does not automatically boot. You can boot the host manually.
For example:
```
# eeprom auto-boot?=false
```
Verify the change.
```
# eeprom auto-boot?
auto-boot?=false
```
