== Configure an IPMI/BMC network

The first step in setting up a BMC is to add the BMC network as a network
object in the cluster management infrastructure. The following settings are
recommended as defaults:

Property Value
Name bmcnet, ilonet, or ipminet
Domain name bmc.cluster, ilo.cluster, or ipmi.cluster
External network false
Base address 10.148.0.0
Netmask bits 16
Broadcast address 10.148.255.255

Once the network has been created, all nodes must be assigned a BMC
interface on this network. The easiest method of doing this is to create the
interface for one node device and then to clone that device several times.

== BMC Authentication ==

The node-installer described in Chapter 6 is responsible for the initialization
and configuration of the BMC interface of a device. In addition to
a number of network-related settings, the node-installer also configures
BMC authentication credentials. By default BMC interfaces are configured
with username ADMIN and a random password that is generated
during the installation of the head node. The values can be read with the
“get” command of cmsh in partition mode.
Changing the BMC authentication credentials is currently only possible
through cmsh.
For example, the current values of the BMC username and password
for the entire cluster can be obtained and changed as follows:
Example
[bright61]% partition use base
[bright61->partition[base]]% get bmcusername
ADMIN
[bright61->partition[base]]% get bmcpassword
Za4ohni1ohMa2zew
[bright61->partition[base]]% set bmcusername bmcadmin
[bright61->partition*[base*]]% set bmcpassword
enter new password: ******
retype new password: ******
[bright61->partition*[base*]]% commit
[bright61->partition[base]]%
It is possible to change the authentication credentials cluster-wide or
by category. Category settings override cluster-wide settings. The relevant
properties are:

Property Description
BMC User ID User type. Normally set to 2 for administrator
access.
BMC User Name User name
BMC Password Password for specified user name
The cluster manager stores the configured BMC username and password.
These are used:
• to configure the BMC interface from the node-installer
• to authenticate to the BMC interface after it has come up
BMC management operations, such as power cycling nodes and collecting
hardware metrics, can then be performed.

== Interfaces Settings ==

Interface Name
It is recommended that the network device name of a BMC interface start
with ipmi or ilo, according to whether the BMC is running with IPMI or
iLO. Numbers are appended to the base name, resulting in, for example:
ipmi0.

Obtaining The IP address
BMC interfaces can have their IP addresses configured statically, or obtained
from a DHCP server.
Only a node with a static BMC IP address has BMC power management
done by Bright Cluster Manager. A node with a DHCP-assigned
BMC IP address, requires custom BMC power management (section 5.1.4)
due to its dynamic nature.
