Hardware Requirements for SP-Based Discovery

For SP-based discovery to work, manageable servers must comply with the revisions of firmware listed in Manageable Server Firmware Requirements in Sun N1 System Manager 1.3 Site Preparation Guide. See Managing Firmware Updates (Tasks) in Sun N1 System Manager 1.3 Operating System Provisioning Guide for instructions, or refer to Sun System Handbook documentation for your server.

SP-based discovery uses a Service Access Point (SAP) to access server capabilities. A SAP is generically defined as an IP address, protocol, and security credentials. Each hardware platform requires a minimum set of credentials to be discovered. If you do not specify the correct credentials such as Secure Shell (SSH) and Intelligent Platform Management Interface (IPMI) accounts and passwords, the discovery process assumes that the default credentials are configured on the manageable servers. For details about default credentials for each hardware type, see Setting Up Manageable Servers in Sun N1 System Manager 1.3 Site Preparation Guide.

Automatic configuration of credentials is supported for Sun Fire V20z and V40z servers and X4000 series servers, if they are in the factory default state. See Setting Up Manageable Servers in Sun N1 System Manager 1.3 Site Preparation Guide.

If you do specify the login accounts and passwords, the SP-based discovery process configures the credentials you specify. If only one credential is specified, the missing credentials are configured with one of the defaults specified in Setting Up Manageable Servers in Sun N1 System Manager 1.3 Site Preparation Guide.

If you want to disable autoconfiguration, add the following line to the /etc/opt/sun/n1gc/hal.properties file before you run SP-based discovery:

initialize=false

The N1 System Manager must be restarted for the disabling of autoconfiguration to take effect. Note that after autoconfiguration is disabled, any servers in the factory default state cannot be discovered using SP-based discovery until their SSH and IPMI accounts are configured.
