General Information

This section provides information concerning N1 System Manager operational processes.

N1 System Manager Cannot Be Used to Manage System Management Servers

Do not use the N1 System Manager to manage servers that have system management software installed on them such as Sun Management Server, Sun Control Station, and any other system management applications including the N1 System Manager.

Discovery of Servers in the Factory Default State

If discovery is attempted on a provisionable server that is in the factory default state, the N1 System Manager discovery process will automatically attempt to configure the SSH and IPMI accounts on the provisionable server as part of discovery as shown in the following tables.

The discovery process will configure credentials as follows:

Table 4–1 SPARC Architecture Provisionable Server Default Credentials

Type	Telnet Login	Telnet Password
Netra 240 and 440	admin	admin
Sun Fire V210, V240, and V440	admin	admin
Sun Fire T1000 and T2000	admin	admin

Table 4–2 x86 Architecture Provisionable Server Default Credentials

Type	SSH Login	SSH Password	IPMI Login	IPMI Password	SNMP Read Community String
Sun Fire V20z and V40z	admin	admin	-	admin	public
Sun Fire X2100	-	-	Admin	admin	-
Sun Fire X4100 and X4200	root	changeme	root	changeme	public

If you have specified the SSH and IPMI login accounts and passwords, the discovery process will configure the provisionable server using the user-specified credentials. If only one credential is specified, the missing credential will be configured with one of the defaults specified above.

If you want to disable auto configuration, add the following line to the file /etc/opt/sun/n1gc/domain.properties before you run discovery:

com.sun.hss.domain.internal.discovery.initializeDevice=false

The N1 System Manager must be restarted for auto configuration disabling to take effect. Note that once auto configuration is disabled, any servers in factory default state cannot be discovered until their SSH and IPMI accounts are configured. For further information, see Setting Up Provisionable Servers in Sun N1 System Manager 1.2 Site Preparation Guide.

DHCP Service Conflict With N1 Grid Service Provisioning System

If you are using both the N1 System Manager and the N1 Grid Service Provisioning System with the ISP plug-in, you must choose which product you want to use for OS deployment for a given target set of servers. Based on the product chosen for OS deployment, you must ensure that the DHCP service supplied by the other product is manually shut down (as the root user) using operating system commands. Failure to shut the service down might result in unreliable behavior of OS deployment operations as well as potential network related problems.
