Updating the /etc/hosts File

The IP address and the name of your management server must be added to the /etc/hosts. Failure to add the IP address and name will cause Sun N1 System Manager installation to fail.

To Update the /etc/hosts file

Steps

1. Log in as root to the Sun N1 System Manager management server.

2. Verify that the /etc/hosts file has entries for loopback and the server.

   1. Make certain that either of the following loopback entries is in the /etc/hosts file.

      127.0.0.1    localhost

      or

      127.0.0.1    localhost.localdomain    localhost

   2. Make certain that an entry exists for the server and its IP address. For example:

      111.11.111.11 n1mgmt

      where 111.11.111.11 is the IP address of the management server, and n1mgmt is the name of the management server.

      Your /etc/hosts should be similar to the following example:

      127.0.0.1    localhost.localdomain    localhost
      10.5.157.123 n1mgmt

   3. Save and close /etc/hosts.

3. Reboot the N1 System Manager management server.

Next Steps

Validate your N1 System Manager as directed by the following sections of the Sun N1 System Manager 1.1 Administration Guide:

• Log in to and access the N1 System Manager as described by Introduction to Accessing the N1 System Manager in Sun N1 System Manager 1.1 Administration Guide.

• Set up the N1 System Manager accounts as described by Managing Users in Sun N1 System Manager 1.1 Administration Guide.

• Set up the N1 System Manager security roles as described by Managing Roles in Sun N1 System Manager 1.1 Administration Guide.

• Run the N1 System Manager discovery process and set up your provisionable servers as described by Chapter 2, Discovering, Grouping, and Replacing Servers in the Sun N1 System Manager, in Sun N1 System Manager 1.1 Administration Guide.

• Provision an operating system to a provisionable server as described by Chapter 3, Provisioning Operating Systems, OS Updates, and Firmware Updates, in Sun N1 System Manager 1.1 Administration Guide.

If provisioning is successful, you can complete discovery and provisioning of all of your provisionable servers as described by the Sun N1 System Manager 1.1 Administration Guide.

If provisioning of a single server is not successful, refer to Chapter 3, Troubleshooting, in Sun N1 System Manager 1.1 Installation and Configuration Guide for problem resolution procedures.
