Note:

*The services started by svc.startd are referred to as milestones. The milestone concept replaces the traditional run levels that were used in previous versions of Solaris. A milestone is a special type of service that represents a group of services. A milestone is made up of several SMF services. For example, the services that instituted run levels S, 2, and 3 in previous version of Solaris are now represented by milestone services named:

milestone/single-user (equivalent to run level S)

milestone/multi-user (equivalent to run level 2)

milestone/multi-user-server (equivalent to run level 3)

*Shut down the system.

# shutdown -iinit-state -ggrace-period -y

-iinit-state

Brings the system to an init state that is different from the default of S. The choices are 0, 1, 2, 5, and 6.

Run levels 0 and 5 are states reserved for shutting the system down. Run level 6 reboots the system. Run level 2 is available as a multiuser operating state.

No DHCP or Proxy DHCP Offers Were Received

If a DHCP server is not responding to an x86 client's request, you see the following messages:

Intel(R) Boot Agent PXE Base Code (PXE-2.1 build 0.86)

Copyright(C) 1997-2007, Intel Corporation

CLIENT MAC ADDR 00 14 4F 29 04 12 GUID FF2000008 FFFF FFFF FFFF 7BDA264F1400

DHCP......... No DHCP or ProxyDHCP offers were received

PXE-MOF: Exiting Intel Boot Agent

The timeout message indicates that the client is sending a DHCP request and not getting a response. This issue is probably due to an error in the DHCP configuration. Check to see if your client is configured correctly in the DHCP server.

The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11.1 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

Note:

*You have several alternatives for where to install Oracle Solaris 11:

Inside a virtual machine on top of your existing operating system

On the bare metal as a standalone operating system

On the bare metal alongside your existing operating system(s) (multiboot scenario)

Note:

*A user can only assume roles that are assigned to the user's login account.

*After you have set up roles with default Solaris rights profiles, and assigned the roles to users, the roles can be used. A role can be assumed on the command line. In the Solaris Management Console, a role can also be used for administering the system locally and over the network.

*How to Assume a Role in a Terminal Window

The role must already be assigned to you. The name service must be updated with that information.

In a terminal window, determine which roles you can assume.

% roles

Comma-separated list of role names is displayed

Use the su command to assume a role.

% su -rolename

Password:

$

The su - rolename command changes the shell to a profile shell for the role. A profile shell recognizes security attributes (authorizations, privileges, and set ID bits).

Verify that you are now in a role.

$ /usr/ucb/whoami

rolename

You can now perform role tasks in this terminal window.

TFTP Error or System Hangs After GATEWAY Message

The DHCP server provides an IP address and a location of the initial boot program as part of the DHCP response.

If the boot program does not exist, then the AI client boot cannot proceed. The following message is displayed:

Intel(R) Boot Agent PXE Base Code (PXE-2.1 build 0.86)

Copyright(C) 1997-2007, Intel Corporation

CLIENT MAC ADDR 00 14 4F 29 04 12 GUID FF2000008 FFFF FFFF FFFF 7BDA264F1400

CLIENT IP: 10.6.68.29 MASK: 255.255.255.0 DHCP IP: 10.6.68.49

GATEWAY: 10.6.68.1

TFTP.

B(not C):A zone is a virtualized operating system environment that is created within a single instance of the Oracle Solaris operating system. Oracle Solaris Zones are a partitioning technology that provides an isolated, secure environment for applications.

Note:

*When you create a zone, you produce an application execution environment in which processes are isolated from the rest of the system. This isolation prevents a process that is running in one zone from monitoring or affecting processes that are running in other zones. Even a process running with root credentials cannot view or affect activity in other zones. A zone also provides an abstract layer that separates applications from the physical attributes of the machine on which the zone is deployed. Examples of these attributes include physical device paths and network interface names. The default non-global zone brand in the Oracle Solaris 11.1 release is the solariszone.

By default, all systems have a global zone. The global zone has a global view of the Oracle Solaris environment that is similar to the superuser (root) model. All other zones are referred to as non-global zones. A non-global zone is analogous to an unprivileged user in the superuser model. Processes in non-global zones can control only the processes and files within that zone. Typically, system administration work is mainly performed in the global zone. In rare cases where a system administrator needs to be isolated, privileged applications can be used in a non-global zone. In general, though, resource management activities take place in the global zone.

There are no upgrade methods or tools available to transition from Oracle Solaris 10 to Oracle Solaris 11. You cannot use an installer to upgrade from Oracle Solaris 10 to Oracle Solaris 11.

Oracle Solaris 11 Transition Tools and Features

Note:

*There are no upgrade methods or tools available to transition from Oracle Solaris 10 to Oracle Solaris 11. You cannot use an installer to upgrade from Oracle Solaris 10 to Oracle Solaris 11.

/JumpStart Migration Utility (js2ai)

Used to convert Oracle Solaris 10 JumpStart rules and profiles to a format that is compatible with AI manifest entries.

/ZFS shadow migration feature

Used to migrate data from an existing file system to a new file system.

/Oracle Solaris 11 support for Oracle Solaris 10 zones

Used to migrate your Oracle Solaris 10 application environments to an Oracle Solaris 11 system.

/NFS file sharing and pool migration

Used to access shared files from an Oracle Solaris 10 system on an Oracle Solaris 11 system.

Used to import a ZFS storage pool from an Oracle Solaris 10 system into an Oracle Solaris 11 system.

Thex86 systems cannot be told to network boot like sparc systems (ie. boot net - install).

Note:

*How to Boot a SPARC Based System From the Network

1.Become the root role.

2.If necessary, bring the system to the ok PROM prompt.

# init 0

3.Boot the system from the network without using the ”install ”flag.

ok boot net:dhcp

Note - If you have changed the PROM setting to boot with DHCP by default, you only have to specify boot net, as shown here:

ok boot net

Note:

*Oracle Solaris 11 adds transparent data encryption functionality to ZFS. All data and file system metadata (such as ownership, access control lists, quota information, and so on) are encrypted when stored persistently in the ZFS pool.

*A ZFS pool can support a mix of encrypted and unencrypted ZFS data sets (file systems and ZVOLs). Data encryption is completely transparent to applications and other Oracle Solaris file services, such as NFS or CIFS. Since encryption is a first-class feature of ZFS, we are able to support compression, encryption, and deduplication together. Encryption key management for encrypted data sets can be delegated to users, Oracle Solaris Zones, or both. Oracle Solaris with ZFS encryption provides a very flexible system for securing data at rest, and it doesn't require any application changes or qualification.

ZFS makes it easy to encrypt data and manage data encryption. You can have both encrypted and unencrypted file systems in the same storage pool. You can also use different encryption keys for different systems, and you can manage encryption either locally or remotely.
