Operating the Oracle Solaris OS With Oracle VM Server for SPARC

This section describes how the Oracle Solaris OS behavior changes when you run an Oracle VM Server for SPARC configuration.

OpenBoot Firmware Not Available After the 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 by using the Oracle Solaris OS halt command.

Performing a Power Cycle of a Server

Whenever performing any maintenance on a system running Oracle VM Server for SPARC software that requires you to perform a power cycle of the server, you must save the configuration of your current logical domains to the SP first.

To save your SP configuration to the SP, use the following command:

ldm add-spconfig config-name

Starting a Domain

Use the ldm start-domain command to start one or more domains. You can also specify an XML configuration file to start a logical domain.

Use the ldm start-domain -f command to enable a guest domain and its I/O service domains to boot simultaneously. The –f option starts a guest domain even when its SR-IOV service domain or domains are not running. The guest domain does not boot successfully if the missing I/O services are essential to the OS boot process. Note that applications running on the guest domain might not function properly if the missing I/O services are essential to the application's operation.

Stopping a Domain

The ldm stop-domain command stops one or more running domains.

If the domain runs the Logical Domains Manager agent provided by at least the Oracle Solaris 10 1/13 or Oracle Solaris 11.1 OS, the ldm stop-domain command sends a shutdown request to the domain.

If the domain does not run the appropriate Logical Domains Manager agent, the ldm stop-domain command sends a uadmin request to the domain.

You can also specify a number of seconds in which the shutdown command must complete. If this timeout value is exceeded, an ldm stop-domain -q command is issued.

You can use SMF properties to change the default behavior. See the ldmd(8) man page.

For more information about the ldm stop-domain command, see the ldm(8) man page.


Note - If you run the ldm stop-domain -f command for a domain that is at the kmdb prompt, the command fails with the following error message:
LDom domain-name stop notification failed

Result of Oracle Solaris OS Breaks

    You can initiate Oracle Solaris OS breaks as follows:

  1. Press the L1-A key sequence when the input device is set to keyboard.

  2. Enter the send break command when the virtual console is at the telnet prompt.

When you initiate such a break, the Oracle Solaris OS issues 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 Rebooting the Control Domain

    You can use the reboot and shutdown -i 5 commands to reboot the control (primary) domain.

  • reboot:

    • No other domains configured. Reboots the control domain without graceful shutdown, no power off.

    • Other domains configured. Reboots the control domain without graceful shutdown, no power off.

  • shutdown -i 5:

    • No other domains configured. Host powered off after graceful shutdown, stays off until powered on at the SP.

    • Other domains configured. Reboots with graceful shutdown, no power off.
