discover

This command discovers and adds new provisionable servers to be managed by the N1 System Manager.

Description

See Chapter 2 in the Sun N1 System Manager Site Preparation Guide for details on setting up a new provisionable server for discovery.

Each hardware platform requires a minimum set of credentials to be discovered: ALOM-based systems require telnet; Sun Fire V20z and V40z servers require SSH, IPMI, and SNMP; Sun Fire X4000 series systems require SSH and IPMI; and the Sun Fire X2100 server requires IPMI.

Before a server can be discovered, the following conditions must be met:

– You must specify the known authentication credentials for the provisionable server, the server must be in a factory-default state (Sun Fire V20z or V40z servers only), or the server must be configured with the default credentials used by the discovery process. See Setting Up Provisionable Servers in the Sun N1 System Manager Site Preparation Guide for the list of system-specific default credentials that the discovery process uses if you do not specify credentials.

– The management network IP address for the provisionable server is configured and is network accessible by the N1 System Manager.

Synopsis

• Discover and add servers to the N1 System Manager:

  discover ip[,ip...] [group group] [ipmi ipmi] [snmp snmp] [ssh ssh] [telnet telnet]

Parameters

• ip – Specify the management network IP addresses of the provisionable servers you want to discover. You can specify multiple instances of ip in one of the following ways, separated by commas:

  • ip-address – A single management network IP address.

  • ip-address–ip-address – A range of management network IP addresses. Example: 10.5.10.1-10.5.10.100

  • subnet/mask-length – A subnet with a mask length. Example: 10.0.8/24 or 10.0.8.128/28

• group – The name of a server group in which to add the discovered servers. If the server group does not exist, it will be created during the discovery.

• ipmi – Specify the IPMI credentials used to authenticate the discovery process based on the server's management network IP address. The ipmi value is an IPMI user name/password pair. If IPMI credentials are not specified and a Sun Fire V20z ore V40z server is in the factory default state, the discovery process sets the server's IPMI user/password to Null/admin. The default IPMI credentials used for discovery depend on your server model.

• snmp – Specify the SNMP credentials used to authenticate the discovery process based on the server's management network IP address. The snmp format is a read community string for the SNMP credentials. The default SNMP read community string is public.

• ssh – Specify the SSH credentials used to authenticate the discovery process based on the server's management network IP address. The ssh format is a user name/password pair for SSH credentials: ssh-username/ssh-password. If SSH credentials are not specified and a Sun Fire V20z ore V40z server is in the factory default state, the discovery process sets the server's SSH user name/password to admin/admin. The default SSH credentials used for discovery depend on your server model.

• telnet – Specify the telnet credentials used to authenticate the discovery process based on server's management network IP address. The telnet credential is used only by ALOM-based systems. The telnet format is a user name/password pair for telnet credentials: telnet-username/telnet-password. The default telnet credentials used for discovery depend on your server model.
