Use the pkg revert command to restore files to their as-delivered condition.

A:

* If your system has more than one OS installed on the system or more than one root boot environment in a ZFS root pool, you can boot from these boot environments for both SPARC and x86 platforms.

*GRUB, the open source boot loader, is the default boot loader in the Solaris OS.

C:With GRUB based booting, the kernel is loaded by specifying its file name, and the drive, and the partition where the kernel resides. GRUB based booting replaces the Solaris Device Configuration Assistant and simplifies the booting process with a GRUB menu.

Incorrect:

NotE:

*In this implementation of GRUB, the multiboot module is no longer used.

To display information about software packages, refer to the following examples. No special privileges are required to display information about packages.

List the packages that are currently installed on your system:

$ pkg list -H entire

Determine whether a specific package is installed in the current image and whether an update is available.

$ pkg list amp

pkg list: no packages matching 'amp' installed

E:

* Many configuration tasks around name services have moved into the SMF in Solaris 11.

*The Service Management Facility (SMF), first introduced in Oracle Solaris 10, is a feature of the operating system for managing system and application services, and it replaces the legacy init scripting start-up mechanism common to prior releases of Oracle Solaris and other UNIX operating systems. SMF improves the availability of a system by ensuring that essential system and application services run continuously even in the event of any hardware or software failures. SMF is one of the components of the wider Oracle Solaris Predictive Self Healing capability.

Note:

*In Oracle Solaris 11, certain aspects of system configuration have changed, including the migration of several system, network, and naming services configuration to SMF.

*WAN boot

SPARC clients of AI installation over the network must support WAN boot.

To boot over the network, AI requires WAN boot support for SPARC clients. You can check whether your client Open Boot PROM (OBP) supports WAN boot by checking whether network-boot-arguments is a valid variable that can be set in the eeprom.

If the variable network-boot-arguments is displayed, or if the command returns the output network-boot-arguments: data not available, the OBP supports WAN boot and the client can be installed over the network.

*The following command shows how to check the client OBP for WAN boot support.

# eeprom | grep network-boot-arguments

network-boot-arguments: data not available

In this example, the output network-boot-arguments: data not available indicates that the client OBP supports WAN boot.

*Use the configuration element in the AI manifest for the client system to specify non-global zones.

Use the name attribute of the configuration element to specify the name of the zone.

Use the source attribute to specify the location of the config file for the zone.

The source location can be any http:// or file:// location that the client can access during installation.

*The following sample AI manifest specifies two Non-Global Zones: zone1 and zone2

You should replace the server_ip with the ip address of the NFS server.

<!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1">

</ai_instance>

</auto_install>

Storage

ZFS is the root file system on Oracle Solaris 11 offering a superior experience in terms of

manageability, scalability and data integrity. ZFS presents a pooled storage model that

completely eliminates the concept of volumes and the associated problems of partitions,

provisioning, wasted bandwidth and stranded storage. Thousands of file systems can draw

from a common storage pool, each one consuming only as much space as it actually needs. All

operations are copy-on-write transactions ensuring that the on-disk state is always valid.

Incorrect:

Not A:Network Auto-Magic(NWAM)is a project to simplify and automate network configuration on Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various network configurations to be created depending on the current network conditions. The Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network Auto-Magic umbrella.

Not B:Pre-Flight Checker tool which can be used to check whether apps will work without modification on Solaris 11

Not C:Network Auto-Magic is a project to simplify and automate network configuration on Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various network configurations to be created depending on the current network conditions. The Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network Auto-Magic umbrella.

A:dedicated-cpu Resource

The dedicated-cpu resource specifies that a subset of the system's processors should be dedicated to a non-global zone while it is running. When the zone boots, the system will dynamically create a temporary pool for use while the zone is running.

C:s the global administrator in the global zone, you can import raw and block devices into a non-global zone. After the devices are imported, the zone administrator has access to the disk. The zone administrator can then create a new file system on the disk and perform one of the following actions:

Mount the file system manually

Place the file system in /etc/vfstab so that it will be mounted on zone boot

D, E:Booting a zone places the zone in the running state. A zone can be booted from the ready state or from the installed state. A zone in the installed state that is booted transparently transitions through the ready state to the running state. Zone login is allowed for zones in the running state.

Incorrect:

Not F: Sys_time not related to booting a zone.

Use the zpool split command to split a mirrored storage pool, which detaches a disk or disks in the original mirrored pool to create another identical pool.

auto_reboot – Optional. Omitting the auto_reboot attribute is equivalent to setting the value of the attribute to false. By default, AI does not automatically reboot the client after installation. To request automatic reboot of the client after successful installation, specify auto_reboot="true".

Note:

*Example 1 Set the auto_reboot Attribute

$ aimanifest set /auto_install/ai_instance@auto_reboot false
