OpenBoot Configuration Variables

Variable
Default Value
Description
auto-boot-on-error?
false
Controls whether the host attempts to boot after POST detects a hardware reconfiguration or error, and enables the selection of the auto-boot behavior in the presence of detected errors.
  • false – Host does not attempt to boot and stops at the ok prompt.

  • true – When auto-boot? is also set to true, the host automatically attempts to boot from the selected device following a hardware reconfiguration or error, which is necessary for maximum availability.

auto-boot?
true
Controls whether the host automatically boots after a host reset or when the power is turned on.
  • true – Automatically attempts to boot from the devices specified in boot-device.

  • false – Host does not attempt to boot and stops at ok prompt.

boot-command
boot
Specifies the command to be executed when auto-boot? is true.
  • boot – Boot kernel from devices specified in boot-device.

  • boot net – Boot kernel from the network.

  • boot disk1:h – Boot from disk1 partition h.

  • boot tape – Boot default file from tape.

  • boot device-path – Boot from the device specified as device_path. For a list of aliases on your server, type devalias.

boot-device
disk net
Contains the name of the default boot device.

Note -  For booting from an iSCSI device over IPoIB, the boot-device variable shows the path to an eUSB device, and the root partition normally specified there is on the iSCSI device.

boot-file
An optional variable that provides boot arguments that are used when OpenBoot is not in diagnostic mode.
diag-switch?
false
If the value is true, run in the Diagnostic mode.
network-boot-arguments
An optional variable that enables you to set configuration variables to be used by OpenBoot when you perform a WAN boot. Setting this variable takes precedence over any default boot variable value. Refer to the eeprom(1M) man page for details.
pci-probe-policy
all
An optional variable that should only be used on Oracle SuperCluster engineered systems to specify how probing for PCIe devices is conducted. For all other non-SuperCluster systems the value of this property should not be changed, and if changed can result in an unknown system behavior.
