Commands for the Sun Fire 6800/4810/4800/3800 Systems

This section describes the Solaris operating environment specific information for this family of mid-range systems:

Sun Fire 6800 system
Sun Fire 4810 system
Sun Fire 4800 system
Sun Fire 3800 system

This section covers the following topics:

Installing, Booting, and Halting the Solaris Operating Environment

To install and boot the Solaris operating environment for the first time, refer to the "System Power On and Setup" chapter of the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual .

After you have installed the Solaris operating environment, to power on one of the the Sun Fire 6800/48104800/3800 systems, which includes booting the Solaris operating environment, refer to the "Maintenance" chapter of the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual.

To Halt the Solaris Operating Environment

1. Enter the system controller domain console for the domain you want to halt.

Refer to the chapter "System Controller Navigation" or to the chapter "Maintenance" in the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual , which is shipped with your system.

2. From the domain console, as superuser, halt the Solaris operating environment for each domain, by typing init 0 .

root# init 0

ok

IP Multipathing (IPMP) Software

The Solaris operating environment implementation of IPMP provides the following features( TABLE 7-1 ).

TABLE 7-1 IPMP Features
Feature	Description
Failure detection	Ability to detect when a network adaptor has failed and automatically switches over network access to an alternate network adaptor. This assumes that you have configured an alternate network adapter.
Repair detection	Ability to detect when a network adaptor that failed previously has been repaired and automatically switches back (failback) the network access from an alternate network adaptor. This assumes that you have enabled failbacks.
Outbound load spreading	Outbound network packets are spread across multiple network adaptors without affecting the ordering of packets in order to achieve higher throughput. Load spreading occurs only when the network traffic is flowing to multiple destinations using multiple connections.

The IP Network Multipathing (IPMP) software provides three important features:

If your system is configured with an alternate network adapter, then it can failover from one network path to another.

It can also failback to the original network adapter, after it is repaired.

The IP Network Multipathing software also spreads out the outbound network load between the two network adapters, to achieve higher throughput. Load spreading only occurs when the outbound network traffic is flowing to multiple destinations using multiple connections.

For more information on IP network multipathing (IPMP), refer to the System Administration Guide: IP Services , which is available with your Solaris operating environment release. The System Administration Guide: IP Services explains basic IPMP features and network configuration details. This book is available online with your Solaris operating environment release.

Sun StorEdge Traffic Manager Software

The Sun StorEdge trademark Traffic Manager software provides multipath configuration management, I/O load balancing, failover support, and single instance multipath support. For details on these software features, refer to the Sun StorEdge Traffic Manager Software Installation and Configuration Guide , available on the Sun Network Solutions website:

Sun Management Center Software for the Sun Fire 6800/4810/4800/3800 Systems

The Sun Management Center software for the Sun Fire 6800/4810/4800/3800 systems is the graphical user interface for managing these mid-range systems.

To optimize the effectiveness of the Sun Management Center software for the Sun Fire 6800/4810/4800/3800 systems, you must install it on a separate system. The Sun Management Center software for the Sun Fire 6800/4810/4800/3800 systems has the capability to logically group domains and the system controller into a single manageable object, to simplify operations.

The Sun Management Center software for the Sun Fire 6800/4810/4800/3800 systems, once configured, is also the recipient of SNMP traps and events.

To use the Sun Management Center software for the Sun Fire 6800/4810/4800/3800 systems, you must attach the System Controller board to a network. With a network connection, you can view both the command line interface and the graphical user interface. To attach the System Controller board Ethernet port, refer to the installation documentation that was shipped with your system.

For instructions on how to use the Sun Management Center software for the Sun Fire 6800/4810/4800/3800 systems, refer to the Sun Management Center 3.0 Software Supplement for Sun Fire 6800/4810/4800/3800 Systems , which is available online.

syslog Loghost

For information on how to set up the syslog loghost using the system controller software, refer to the chapter "System Power On and Setup" of the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual. This is part of the system controller setupplatform system controller command, which is run when you set up the platform.

For more details on the setupplatform command, refer to the setupplatform command in the Sun Fire 6800/4810/4800/3800 System Controller Command Reference Manual and to the chapter "System Power On and Setup" in the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual . Both of these books are available both hardcopy and online with your Sun Fire 6800/4810/4800/3800 system.

Displaying System Configuration Information

To display system configuration parameters, use the following Solaris operating environment commands:

prtconf Command

The Solaris operating environment prtconf command prints the system configuration information. The output includes:

Total amount of memory
Configuration of the system peripherals formatted as a device tree

This command has many options. For the command syntax, options, and examples, see the prtconf man page.

prtdiag Command

The Solaris operating environment prtdiag (1M) command displays the following information to the domain of your Sun Fire 6800/4810/4800/3800 system:

Configuration
Diagnostic
Total amount of memory

For more information on this command, see the prtdiag (1M) man page.

sysdef Command

The Solaris operating environment sysdef utility outputs the current system definition in tabular form. It lists:

All hardware devices
Pseudo devices
System devices
Loadable modules
Values of selected kernel tunable parameters

This command generates the output by analyzing the named bootable operating system file ( namelist ) and extracting configuration information from it. The default system namelist is /dev/kmem .

For command syntax, options, and examples, see the sysdef man page.

format Command

The Solaris operating environment utility, format , which is used to format drives, can also be used to display both logical and physical device names. For command syntax, options, and examples see the format man page.
