B:This example shows how to create a DLMP aggregation. The aggregation has three underlying datalinks.

# dladm create-aggr -m haonly -l net0 -l net1 -l net2 aggr0

# dladm show-link

LINK CLASS MTU STATE BRIDGE OVER

net0 phys 1500 up -- ----

net1 phys 1500 up -- ----

net2 phys 1500 up -- ----

aggr0 aggr 1500 up -- net0, net1, net2

# dladm show-aggr

LINK MODE POLICY ADDRPOLICY LACPACTIVITY LACPTIMER

aggr0 haonly --

E:Check the status of the aggregation you just created.

# dladm show-aggr

The aggregation's state should be UP.

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.

*Booting a system using the none milestone can be very useful for debugging startup problems. There is no equivalent run level to the none milestone.

*If problems with starting services occur, sometimes a system will hang during the boot. This procedure shows how to troubleshoot this problem.

2.Boot without starting any services.

This command instructs the svc.startd daemon to temporarily disable all services and start sulogin on the console.

ok boot -m milestone=none

2.Log in to the system as root.

3.Enable all services.

# svcadm milestone all

4.Determine where the boot process is hanging.

When the boot process hangs, determine which services are not running by running svcs -a. Look for error messages in the log files in /var/svc/log.

• After fixing the problems, verify that all services have started.

Verify that all needed services are online.

# svcs -x

Verify that the console-login service dependencies are satisfied.

This command verifies that the login process on the console will run.

# svcs -l system/console-login:default

6.Continue the normal booting process.

An M represents a modified file or directory, an R is a renamed filesystem objects.
