Enable or Disable Automatic Booting (OpenBoot)
Use one of these procedures to configure OpenBoot so that a host reset or
power on attempts to boot the OS automatically, or does not. This change is
permanent, but it takes effect only after a host reset.
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.
-
Get to the ok prompt.
See Accessing the OpenBoot Prompt.
-
Set the OpenBoot auto-boot? variable to
true or false.
-
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.
Note -
If you are configuring the host for maximum availability,
configure the host to automatically reboot following either
an error or a hardware reconfiguration by setting
auto-boot? and
auto-boot-on-error? to
true. The default value for
auto-boot-on-error? is
false.
-
false – The host does not
automatically boot. You can boot the host manually.
For example, to change the default setting, type:
{0} ok setenv auto-boot? false
-
Verify the change.
{0} ok printenv auto-boot?
auto-boot? = false
