Overview
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 5-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 (EX436).
Senior Linux system administrators responsible for maximizing resiliency through high-availability clustering services and using fault-tolerant shared storage technologies
Audience
An experienced Linux system administrator responsible for managing shared storage across 1 or more Linux systems, an experienced Linux system administrator responsible for maintaining a high-availability service using cluster technology, an RHCE interested in earning a Red Hat Certificate of Expertise, a Red Hat Certified Datacenter Specialist (RHCDS) or a Red Hat Certified Architect (RHCA) credential.
Skills Gained
As a result of attending this course, students should be able to create, manage, and troubleshoot highly available network services and tightly-coupled cluster storage for business-critical applications.
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
This course is intended to develop the skills needed to produce highly available, more resilient, mission critical applications, resulting in reduced downtime and easier hardware maintenance.
Prerequisites
If you want to take this course without the exam (RH436) and have not earned your RHCE® certification, you can confirm that you have the necessary knowledge by passing the online skills assessment.

Certification
To attend any Red Hat course or exam, you will need to provide us with your unique Red Hat Network ID. If you do not have a Red Hat Network ID you can create one online here. In order to confirm your place on this course CM must share several items of basic personal information with our Partner. Bookings cannot be confirmed without this. If you have any questions or concerns please contact your CM account manager.
If you attend a virtual event, Courseware will be in PDF format and available for download on the first day of the course. Joining Instructions will be sent on the Friday before start date directly from Red Hat which will include the live virtual classroom link.
If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. Its a cost effective option. One on one training can be delivered too, at reasonable rates.
Submit an enquiry from any page on this site and let us know you are interested in the requirements box, or simply mention it when we contact you.
