MetaSchema)� ALL_DISTROS)� PER_INSTANCEa| Reset RMC module is IBM PowerVM Hypervisor specific
Reliable Scalable Cluster Technology (RSCT) is a set of software components,
that together provide a comprehensive clustering environment (RAS features)
for IBM PowerVM based virtual machines. 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.
