Red Hat High Availability Clustering (RH436) provides intensive, hands-on experience with the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, as well as cluster storage components from the Resilient Storage Add-On, including Cluster Logical Volume Manager (CLVM), Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath. This course is based on Red Hat Enterprise Linux 7.1. Created for senior Linux system administrators, this 4-day course strongly emphasizes lab-based activities. You'll learn how to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment. This course also helps you prepare for the Red Hat Certified Specialist in High Availability Clustering exam

Learning Objectives

Students should be able to demonstrate the following skills:
Improve application uptime by using high availability clustering
Manage storage in an high availability environment using iSCSI initiators, HA-LVM or CLVM as appropriate, and GFS2 cluster file systems
Implement strategies to identify single points of failure in high availability clusters and eliminate them
