This course is designed to prepare students to identify and resolve problems on a highly available cluster using PowerHA SystemMirror 7.
The audience for this course is students who are experienced AIX system administrators with TCP/IP networking and AIX Logical Volume Manager (LVM) experience who are responsible for maintaining a PowerHA SystemMirror 7 and later cluster on an IBM Power Systems server running AIX 6.1 or later. The lab exercises are conducted on an AIX 7.1 TL2 -level system.
Describe the config_too_long and event_error cluster event problems and what impact these problems will have on cluster operation
Locate the source of a cluster event problem
Resolve cluster event problems and return the cluster to normal operation
Resolve network and Cluster Aware AIX problems
Resolve C-SPOC and LVM problems
Students attending this course are expected to have:
AIX, TCP/ IP, LVM storage and disk hardware implementation skills
An understanding of PowerHA SystemMirror concepts
The ability to install, configure and manage a two-node cluster
An understanding of basic cluster problem determination and familiarity with PowerHA SystemMirror log files
These skills are addressed in the following course and its prerequisites ( or can be obtained through equivalent education and experience):
PowerHA SystemMirror 7: Planning, Implementation, Customization and Basic Administration (AN610)

Exercise 4: Resolving network, CAA, and RSCT problems
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. It's a cost effective option.
