Sun N1 System Manager 1.3.1 What's New

Discovering the Sun Blade 8000 Modular System And Any Installed Sun Blade X8400 Server Modules

N1 System Manager discovers Sun Blade X8400 Server Modules in the same manner as other servers. You can discover any installed Sun Blade X8400 Server Modules by specifying a range of addresses that include the SP IP addresses of Sun Blade X8400 Server Modules, or by the operating system installed on Sun Blade X8400 Server Modules.

N1 System Manager does not discover the Sun Blade 8000 Chassis through its SP or SC IP address. Sun Blade 8000 Chassis is discovered when you use N1 System Manager to discover Sun Blade X8400 Server Modules installed in the chassis.

For further information about discovery methods, see Chapter 4, Discovering Manageable Servers, in Sun N1 System Manager 1.3 Discovery and Administration Guide.

Note –

The capability of N1 System Manager to manage a Sun Blade 8000 Chassis and any installed Sun Blade X8400 Server Modules depends on the discovery method. These capabilities are identical to the Sun FireTM X4000 server management capabilities described in Capability of Managed Servers Based on Discovery in Sun N1 System Manager 1.3 Discovery and Administration Guide.

If any installed Sun Blade X8400 Server Modules are discovered using SP-based discovery, the discovery process automatically places them into a special group called a chassis group, with a group name of the form cmm-chassisID, where chassisID is the hardware ID of the Sun Blade 8000 Chassis containing each discovered Sun Blade X8400 Server Module.

Chassis groups are displayed by N1 System Manager in the same way as user-defined groups of servers. For details about defining and managing groups of servers, see Chapter 5, Managing Servers and Server Groups, in Sun N1 System Manager 1.3 Discovery and Administration Guide. The cmm- prefix of the chassis group name is reserved for Sun Blade 8000 Chassis, and enables you to quickly identify each chassis and the Sun Blade X8400 Server Modules installed in the chassis. Additionally, the discovery process retrieves additional server information about each Sun Blade X8400 Server Module, including PXE boot devices, and UUID.

If the Sun Blade X8400 Server Modules are discovered using OS-based discovery, the discovered Sun Blade X8400 Server Modules are not shown in the chassis server group context.

Discovery also provides the capability of placing discovered blades in an existing logical server group as described in the following procedure.

ProcedureTo Discover Sun Blade X8400 Server Modules

  1. Log in to the N1 System Manager browser interface.

    See Chapter 1, Accessing the N1 System Manager, in Sun N1 System Manager 1.3 Discovery and Administration Guide.

  2. Select an existing logical server group, or create and then select a new logical server group.

    For group creation procedures, see To Create a Group of Managed Servers in Sun N1 System Manager 1.3 Discovery and Administration Guide.

  3. Use SP-based discovery, specifying the range of Sun Blade X8400 Server Module SP IP addresses.

    Use the discover command to discover a Sun Blade X8400 Server Module through its SP.


    N1-ok> discover IP,IP-IP,subnet/mask format ip [group group]
[ipmi username/password] 
[ssh username/password]

    IP addresses, IP address ranges, and IP subnets can be input as a comma-separated list. Overlapping IP address ranges are allowed.

    Note –

    When you specify the range of IP addresses for discovery, ensure that the IP address range does not include the IP addresses of the N1 System Manager management server.

    Security credentials for IPMI, Simple Network Management Protocol (SNMP), SSH and Telnet are optional. If credentials are not specified, the manufacturer defaults are used. See Sun N1 System Manager 1.3 Site Preparation Guide for information about the default accounts.

    See discover in Sun N1 System Manager 1.3 Command Line Reference Manual for more details about the syntax used in the discover command.

    After successful completion of the Discovery job, a managed server is identified by its management name. If the Sun Blade X8400 Server Module was discovered using SP-based discovery, its management name is initially set to its management IP address. You can rename discovered servers at any time, to a name of your choosing, by using the set server command as described in set server in Sun N1 System Manager 1.3 Command Line Reference Manual. When you name a Sun Blade X8400 Server Module using the set server command, the name does not change if you move the Sun Blade X8400 Server Module to another chassis.

    For more information, see SP-Based Discovery in Sun N1 System Manager 1.3 Discovery and Administration Guide

    After discovery, each discovered Sun Blade X8400 Server Module is placed into the selected logical server group and into a chassis server group. You can add discovered Sun Blade X8400 Server Modules to more than one logical server group, for various group level tasks, providing additional management functionality.

Detecting Duplicate Sun Blade X8400 Server Modules

Under certain conditions, N1 System Manager can discover the same server more than once, resulting in duplicate servers. See Discovering and Identifying Duplicate Servers in Sun N1 System Manager 1.3 Discovery and Administration Guide for details.

When manually discovering a Sun Blade 8000 Modular System server, if you do not specify the correct guid, the detectduplicates command does not work properly for that manually discovered Sun Blade 8000 Modular System. When manually discovering Sun Blade X8400 Server Modules, if specifying a guid in the manual discovery XML file, ensure therefore that you specify the correct guid.
