Operating the Oracle Solaris OS With Oracle VM Server for SPARC

This section describes the changes in behavior in using the Oracle Solaris OS that occur once a configuration created by the Logical Domains Manager is instantiated.

OpenBoot Firmware Not Available After Oracle Solaris OS Has Started

The OpenBoot firmware is not available after the Oracle Solaris OS has started because it is removed from memory.

To reach the ok prompt from the Oracle Solaris OS, you must halt the domain. You can use the Oracle Solaris OS halt command to halt the domain.

Powercycling a Server

Whenever performing any maintenance on a system running Oracle VM Server for SPARC software that requires powercycling the server, you must save your current logical domain configurations to the SP first.

How to Save Your Current Domain Configurations to the SP

Use the following command.
```
# ldm add-config config-name
```

Do Not Use the `psradm`(1M) Command on Active CPUs in a Power-Managed Domain

Do not attempt to change an active CPU's operational status in a power-managed domain by using the psradm command.

Result of Oracle Solaris OS Breaks

The behavior described in this section is seen when you do the following:

Press the L1-A key sequence when the input device is set to keyboard.
Enter the send break command when the virtual console is at the telnet prompt.

After these types of breaks, you receive the following prompt:

c)ontinue, s)ync, r)eset, h)alt?

Type the letter that represents what you want the system to do after these types of breaks.

Results From Halting or Rebooting the Control Domain

The following table shows the expected behavior of halting or rebooting the control (primary) domain.

Table 12-1 Expected Behavior of Halting or Rebooting the Control (primary) Domain

Command	Other Domain Configured?	Behavior
`halt`	Not Configured	Host powered off and stays off until powered on at the SP.
	Configured	Soft resets and boots up if the variable `auto-boot?=true`. Soft resets and halts at ok prompt if the variable `auto-boot?=false`.
`reboot`	Not Configured	Reboots the host, no power off.
	Configured	Reboots the host, no power off.
`shutdown -i 5`	Not Configured	Host powered off, stays off until powered on at the SP.
	Configured	Soft resets and reboots.

For information about the consequences of rebooting a control domain that has the root domain role, see Rebooting the primary Domain.
