This section describes new boot features in the Oracle Solaris release. For a complete listing of new features and a description of Oracle Solaris releases, see Oracle Solaris 10 1/13 What’s New.The following is a list of new features:
Two-Terabyte Disk Support for Installing and Booting Oracle Solaris 10
x86: Support for Using Power Button to Initiate System Shutdown
The Fast Reboot feature of Oracle Solaris is now supported on the SPARC platform. The integration of Fast Reboot on the SPARC platform enables the -f option to be used with the reboot command to accelerate the boot process by skipping certain POST tests.
The Fast Reboot feature of Oracle Solaris is managed through SMF and implemented through a boot configuration service, svc:/system/boot-config. The boot-config service provides a means for setting or changing the default boot configuration parameters. When the config/fastreboot_default property is set to true, the system performs a fast reboot automatically, without the need to use the reboot -f command. By default, this property value is set to false on the SPARC platform.
Note - On the SPARC platform, the boot-config service also requires the solaris.system.shutdown authorization as the action_authorization and value_authorization.
To make Fast Reboot the default behavior on the SPARC platform, use the svccfg and svcadm commands.
For task-related information, see Accelerating the Reboot Process on the SPARC Platform (Task Map).
Oracle Solaris 10 9/10: For information on auto registration, see Chapter 17, Working With Oracle Configuration Manager
Oracle Solaris 10 9/10: Starting with this release, boot archive recovery on the SPARC platform is automatic.
To support auto-recovery of the boot archives on the x86 platform, a new auto-reboot-safe property has been added to the boot configuration service, svc:/system/boot-config:default. By default, the property's value is set to false to ensure that the system does not automatically reboot to an unknown boot device. If the system is configured to automatically point to the BIOS boot device and GRUB menu entry that Oracle Solaris 10 is installed on, you can set the property's value to true. Setting the value to true enables an automatic reboot of the system for the purpose of recovering an out-of-date boot archive.
To set or change this property's value, use the svccfg and svcadm commands. See the svccfg(1M) and svcadm(1M) man pages.
For general information about this enhancement, see the boot(1M) man page.
For step-by-step instructions, see x86: How to Clear Automatic Boot Archive Update Failures by Using the auto-reboot-safe Property.
Oracle Solaris 10 9/10: Starting with this release, the itu utility has been modified to support booting a SPARC based system with Install-Time Updates (ITUs). Third-party vendors can now deliver driver updates on floppy disk, CD or DVD, and USB storage. In addition, new tools that enable you to modify the Oracle Solaris installation media with new packages and patches have been introduced. These tools can be used to deliver software updates for hardware platforms and to produce customized installation media. For task-related information, see SPARC: How to Boot a System With a Newly Created ITU.
See also the following man pages:
Solaris 10 10/09: In previous releases, you could not install and boot the Solaris OS from a disk that was greater than 1 Tbyte in size. Starting with this release, you can install and boot the Oracle Solaris OS from a disk that is up to 2 Tbytes in size. In previous releases, you also had to use an EFI label for a disk that was larger than 1 Tbyte. In this release, you can use the VTOC label on any size disk. However, the addressable space by the VTOC label is limited to 2 Tbytes.
For more information, see What’s New in Disk Management? in System Administration Guide: Devices and File Systems.
Solaris 10 10/08: This release includes Oracle Solaris ZFS installation, as well as ZFS boot support. You can now install and boot from a ZFS root file system. This enhancement applies to both the SPARC and x86 based platforms. Booting, system operations, and installation procedures have been modified to support this change.
For more information, see Booting From an Oracle Solaris ZFS Root File System.
All Oracle Solaris installation methods, including Solaris Live Upgrade, now use the findroot command for specifying which disk slice on an x86 based system to boot. This implementation supports booting systems with Oracle Solaris ZFS roots, as well as UFS roots. Previously, the root command, root (hd0.0.a), was used to explicitly specify which disk slice to boot. This information is located in the menu.lst file that is used by GRUB.
The most common form of the GRUB menu.lst entry is now as follows:
findroot (rootfs0,0,a) kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS module$ /platform/i86pc/$ISADIR/boot_archive
In some Oracle Solaris 10 releases, the entry is as follows:
findroot (pool_rpool,0,a) kernel$ /platform/i86pc/multiboot -B $ZFS-BOOTFS module /platform/i86pc/boot_archive
For more information, see x86: Implementation of the findroot Command.
A new -p option has been added to the bootadm command.
This option enables you to specify the platform or machine hardware class of a client system in situations where the client platform differs from the server platform, for example when administering diskless clients.
Note - The -p option must be used with the -R option.
# bootadm -p platform -R [altroot]
The specified platform must be one of the following:
i86pc
sun4u
sun4v
For more information, see the bootadm(1M) man page.
The Oracle Solaris SPARC bootstrap process has been redesigned to increase commonality with the x86 boot architecture.
Other enhancements include an improved boot architecture that supports booting a system from additional file system types, for example an Oracle Solaris ZFS file system, or a single miniroot, for installation, as well as booting from DVD, NFS, or HTTP. These enhancements increase flexibility and reduce maintenance requirements on SPARC based systems.
As part of this redesign, the boot archives and the bootadm command, previously only available on the x86 based platform, are now an integral part of the SPARC boot architecture.
The primary difference between the SPARC and x86 boot architectures is how the boot device and file are selected at boot time. The SPARC based platform continues to use the OpenBoot PROM (OBP) as the primary administrative interface, with boot options selected by using OBP commands. On x86 based systems, these options are selected through the BIOS and the GRand Unified Bootloader (GRUB) menu.
Note - Although the SPARC boot process has changed, no administrative procedures for booting a SPARC based system have been impacted. Boot tasks performed by the system administrator remain the same as they were prior to the boot architecture redesign.
For more information, see the boot(1M) and bootadm(1M) man pages.
For more information in this document, see Understanding the New SPARC Boot Architecture.
Pressing and releasing the power button on x86 based systems initiates a clean system shutdown and turns the system off. This functionality is equivalent to using the init 5 command to shut down a system. On some x86 based systems, the BIOS configuration might prevent the power button from initiating shutdown. To enable use of the power button to perform a clean system shutdown, reconfigure the BIOS.
Note - On certain x86 based systems that were manufactured before 1999 and are running an older release, pressing the power button immediately turns off system power without safely shutting it down. This same behavior occurs when you press the power button on systems running with ACPI support that is disabled through the use of acpi-user-options.
For more information about acpi-user-options, see the eeprom(1M) man page.
