Management Server Configuration

This section provides the procedures for resolving problems with the management server configuration files.

To Update the /etc/hosts File

Step

Edit /etc/hosts and ensure that the entries are similar to the following example:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1           localhost
111.222.333.44     machine-name loghost

where 111.222.333.44 is the IP address of the N1 System Manager server, and machine-name is the name of the N1 System Manager management server.

For example, if the machine name is n1manager, and the assigned IP address for eth0 is 129.123.111.12, then the /etc/hosts file should contain the following settings:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1          localhost.localdomain localhost
129.123.111.12     n1manager loghost

You must reboot the system after updating the /etc/hosts file.

To Update the /etc/resolv.conf File

Step

Edit /etc/resolv.conf and ensure that the entries are similar to the following:

nameserver server 1 IP address
nameserver name server 2 IP address
nameserver name server 3 IP address
domain your-domain-name
search your-domain-name

For example, assume the IP address of the first DNS server is 129.123.111.12, the second DNS server is 129.123.111.24, and the third DNS server is 129.123.111.36. If your company domain name is mydomain.com, then the /etc/resolv.conf file would contain the following lines.

nameserver 129.123.111.12
nameserver name 129.123.111.24
nameserver name 129.123.111.36
domain mydomain.com
search mydomain.com

To Disable Provisionable Server Automatic Configuration

The following procedure disables the automatic configuration of provisionable servers during discovery.

Step

Edit the /etc/opt/sun/n1gc/domain.properties file and add the following line to the file:

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

The N1 System Manager system must be restarted for auto configuration disabling to take effect. Note that once auto configuration is disabled, any servers in a factory default state cannot be discovered until their SSH and IPMI accounts are configured.
