RSCT includes the Resource monitoring and control (RMC) subsystem. RMC is a generalized framework used for managing, monitoring, and manipulating resources. RMC runs as a daemon process on individual machines and needs creation of unique node id and restarts during VM boot. More details refer https://www.ibm.com/support/knowledgecenter/en/SGVKBA_3.2/admin/bl503_ovrv.htm This module handles - creation of the unique RSCT node id to every instance/virtual machine and ensure once set, it isn't changed subsequently by cloud-init. In order to do so, it restarts RSCT service. Prerequisite of using this module is to install RSCT packages.
