NIM Overview

NIM Overview​

NIM stands for Network Installation Management, which is a system management framework used to manage the installation and maintenance of AIX operating systems. NIM allows administrators to perform various operations on NIM clients, such as software or Base Operating System (BOS) installation, Service Pack (SP) or Technology Level (TL) updates, and reboots.

NIM Master Server​

The NIM master server is responsible for managing NIM clients and resources. It can be configured and managed using the NIM module. The NIM module provides functionality to perform operations like setting up the NIM master server, managing NIM objects, and executing commands on NIM clients.

NIM Module Actions​

The module includes various actions such as update, master_setup, check, compare, script, allocate, deallocate, bos_inst, define_script, remove, reset, reboot, maintenance, show, and register_client to manage NIM operations.

NIM Module Requirements​

The NIM module requires AIX version 7.1 TL3 or newer, Python 3.6 or newer, and a user with root authority to run the NIM command.
