Welcome to VERITAS!

This course is the first step to learning the wild and wonderful world of VERITAS Volume Manager. This course is absolutely necessary for you to continue on to the future courses, and if you already know this stuff it's at least a good review.

Before we start, there are a couple of things you need to know about me (your humble narrator).

Why I'm Doing This

You may, or may not, be curious as to why I'd waste part of my life writing these courses. You may also have already noticed (from the preceding course) that I am not a professional instructor. Well, you're right: I'm not a professional instructor. I am, however, a UNIX systems admin who specializes in Sun Enterprise Storage Systems. I won't bore you with the story of how I got to where I am, but for several months I wanted to learn VERITAS, and no one could teach me more, and I couldn't afford classes. I begged my company to get me materials or a class on the subject to no avail. So, I learned VERITAS the hard way. I downloaded the manuals from Sun and studied them for a couple of weeks, before I got a contract that would let me actually experience VERITAS first hand. The bottom line here is that some of the concepts took days and weeks of rolling over and over in my head before I fully understood them. These documents, and the courses I teach, are my way of helping you get the most out of VERITAS and the VERITAS manuals the FIRST time you read them. Hopefully, you'll be understanding VERITAS in days or hours instead of weeks. This is my way of "giving back" to the community. I am not an "expert", nor is anyone an "expert". I'm just sharing the knowledge I've gained during the last year. My teachings have done well for many others that I've taught, so I hope you'll pick up a lot from these writings.

Now, on with the show!

HOWEVER, you can find the VERITAS VM 2.6 documentation on To get the docs (available in HTML or PDF), go to Then click on "Browse By Collection". Then search down the list (toward the bottom) until you find "Sun StorEdge Volume Manager 2.6 AnswerBook". Click on that. Then you'll see three titles:
