培训课程: PowerHA/XD:Extended Distance and Disaster Recovery
课程代号：AN44CN

课程介绍
This course is designed to teach PowerHA for AIX professionals the techniques used to plan for, configure, and manage PowerHA/XD using Geographic Logical Volume Manager (GLVM), Metro Mirror, or Global Mirror as the data replication method. 

授课对象
PowerHA for AIX system administrators and support personnel who will be responsible for the implementation and maintenance of  Power p systems running PowerHA/XD clusters.
The course is aimed at the following audience:
Students who wish to understand PowerHA/XD concepts and how it can be used to provide automated disaster recovery.
Students who wish to learn about how to implement GLVM, Metro Mirror or Global Mirror as a data replication method for PowerHA/XD.
Students who wish to learn about how to manage PowerHA/XD for GLVM clusters. 

预备技能
Students should have experience with installing and performing standard PowerHA for AIX configuration functions, which can be obtained through either of the following courses (or equivalent experience):
HACMP System Administration I: Planning and Implementation (AU54), or
PowerHA for AIX I: Implementation, Configuration and Administration (AN41)
Note: AU54, AN41, or similar experience is a mandatory prerequisite.
Students should also have experience with the following skills, which are prerequisites for The principles of good system management (AN44); TCP/IP Communications Concepts and Tools as covered in AU07/AN21; and LVM Concepts and Configuration as covered in AU14/AN12, and AU16/AN15.
