The Veritas InfoScale Storage 7.3 for UNIX/Linux: Administration course is designed for the IT professional tasked with installing, configuring, and maintaining Veritas InfoScale Storage environments, including Volume Manager (VxVM), File System (VxFS), and Cluster File System (CFS).

This class covers how to use InfoScale Storage to manage disks, disk groups, and volumes by using a variety of InfoScale Storage user interfaces, including the Veritas InfoScale Operations Manager (VIOM) Web console. You learn the basics of online file system administration and recovery from disk failures. In addition, you learn about data replication using Veritas File Replicator and Veritas Volume Replicator. You also learn how to configure Veritas Cluster Volume Manager and Veritas Cluster File System.

By the completion of this course, you will be able to:

• Describe how clustering is used to implement high availability in the data center environment.
• Describe VCS and cluster communication mechanisms.
• Create a cluster, and configure service groups and resources.
• Implement and verify failover and failback capability. for application, storage, and network services.
• Configure and optimize cluster behavior.
• Protect data in a shared storage environment.
• Describe I/O fencing operations, and its implementation.
• Configure VCS to manage an Oracle database and other applications.
• Configure a global cluster environment, including remote clusters, global heartbeats, and global service groups.
• Configure notification and failover behavior in a global cluster.

This course is for Linux system administrators, system engineers, technical support personnel, network/SAN administrators, and systems integration/development staff, who will be installing, operating, or integrating InfoScale Availability.
