Manage the InfiniBand Network Using
Subnet Manager
This chapter describes how to manage the InfiniBand Network Using Subnet Manager
in your Exalogic machine.
This chapter contains the following sections:
• Understand Administrative Commands
• Manage InfiniBand Network Using Subnet Manager
• Work with the Default Rack-Level InfiniBand Partition
13.1 Understand Administrative Commands
The following topics provide an overview of administrative tasks and the command
sets to perform those tasks. Administering the gateway requires accessing the
command-line interface (CLI), which is also referred to as the management controller.
This section contains the following topics:
• Hardware Command Overview
• InfiniBand Command Overview
13.1.1 Hardware Command Overview
The CLI (management controller) uses a simplified Linux operating system and file
system. From the # prompt on the CLI, you can type hardware commands to perform
some administrative and management tasks. Hardware commands are user-friendly
and can perform some testing upon the switch chip, enabling greater control of a
gateway switch and its operation.
After you log in to the
root
account, the shell prompt (#) appears, and you can enter
shell commands. Enter the hardware commands in the following format:
# command [arguments][arguments]...
13.1.2 InfiniBand Command Overview
The InfiniBand commands are a means of monitoring and controlling aspects of the
InfiniBand fabric. These commands are also installed on and run from the CLI, which
is also the host of the Subnet Manager. Use of these commands requires thorough
knowledge of InfiniBand architecture and technology.
After you log in to the
root
account, the shell prompt (#) appears, and you can enter
shell commands. Enter the InfiniBand commands in the following format:
# command [option][option] ...
