Sun Microsystems Netra T2000 - Selecting a Boot Device

Chapter 4 Basic Administrative Tasks 43
When the user sets an alarm, a message is displayed on the console. For example,
when the critical alarm is set, the following message is displayed on the console:
In certain instances when the critical alarm is set, the associated alarm indicator is
not lit. This implementation is subject to change in future releases.
Selecting a Boot Device
The boot device is specified by the OpenBoot configuration variable boot-device.
The default setting of this variable is disk net. With this setting, the firmware first
attempts to boot from the system hard drive, and if that fails, from the on-board
NET0 Gigabit Ethernet interface.
This procedure assumes that you are familiar with the OpenBoot firmware and that
you know how to enter the OpenBoot environment. For more information, see
“OpenBoot PROM” on page 27.

* The user can shut down the system using commands such as init0 and init6. These commands do not remove power from the sys-
tem.
† Based on a determination of the fault conditions, the user can turn the alarm on using the Solaris platform alarm API or ALOM CLI.
‡ The implementation of this alarm indicator state is subject to change.
§ NC state is the normally closed state. This state represents the default mode of the relay contacts in the normally closed state.
