Boot and Restart Overview
Note - This topic uses PDomain_0 as an example.
Use OpenBoot and Oracle Solaris commands to reconfigure the host's boot and restart behavior permanently or temporarily. Oracle ILOM boot mode properties can help specify how the host boots, enabling you to correct a problem with the current settings in OpenBoot or Oracle VM Server for SPARC.
Note - The boot sequence has changed to accommodate booting from an iSCSI device over IPoIB. For information about these changes, see Boot Sequence and iSCSI Devices Using IPoIB. For detailed descriptions of the changes and instructions on how to manage the new infrastructure, refer to the Oracle Solaris documentation (http://www.oracle.com/pls/topic/lookup?ctx=solaris11).
For more comprehensive information about customizing how the host boots, refer to the Oracle Solaris documentation for your release.
You can also secure the boot process by using Verified Boot, which verifies the boot blocks, unix, and geunix. You can set the Boot Policy (boot_policy) property in Oracle ILOM to none (default), warning, or enforce. The warning setting sends a warning to the Oracle Solaris OS console, and it allows the boot process to proceed. The enforce setting sends a warning to the Oracle Solaris console, but it does not allow the boot process to proceed. You can set the boot_policy property from /Servers/PDomains/PDomain_0/host/verified_boot.
 | Caution - The enforce setting does not allow the boot process to proceed if the OpenBoot use-nvramrc? variable is set to true. You can directly set the use-nvramrc? variable with the setenv command, or the variable is set to true when you use the nvalias command. If you set the use-nvramrc? variable to false, you will not be able to create device aliases with the nvalias command. |
