Product Review
Are you running a busy data warehouse or transaction center that's based on Sun Microsystems hardware and software? Then you're certainly interested in doing all you can to maximize the reliability of your system. In the
Guide to High Availability: Configuring boot/root/swap, Jeannie Johnstone Kobert shares a series of specific procedures you can perform to improve the robustness of a system disk.
In her examples, Kobert explicitly covers Sun Ultra 2 workstations, Enterprise 4000 and 5000 servers, A5000 subsystems, and UniPack and MultiPack storage systems. Additionally, the procedures apply to Enterprise 250, 450, 3000, and 6000 servers and all hot-swappable StorEdge products. This book shows how to mirror the system disk (using both Solstice DiskSuite and Enterprise Volume Manager). It shows how to make a system fail over to a mirror of the system disk when there's trouble, and details how to anticipate, detect, and recover from disk failures.
The book leaves little to the imagination, presenting critical information clearly and succinctly. It's easy to follow the author's explicit procedures, which are backed up with screen dumps that show commands and their output. Because of its liberal use of machine input and output, this book is great for studying in advance of "major surgery"--operators will know what to expect from their machines and will not waste time figuring out what output means.
--David Wall Topics covered: System disk mirroring, failure detection and recovery, hot swapping of the system disk, MultiPack and UniPack configuration, and alternate boot paths.
Book Info
Focuses on the system disk, providing configuration and recovery details for all Sun Servers. Provides a
cook book approach to ensuring system disk availability. Softcover.
Reader ReviewsThis book is 100 pages end to end, and still full of air. There are screen shots and command-line invocations in boxes all over it, and it feels like padding. There are *no* explanations of the practical design ideas given, other than asuch as "this solution will scale." Most solutions will scale if you use two disks arrays. Given the configuration in the book, the scaling bootable disk system is a mere [$$$] away. Nice. "If you want to do it the way we do it, here's how..." is the entire conceptual approach to the title. The text does say it's a "cookbook" in its intro, but [$$$] is a lot to ask for that. I expect anyone who wants to make money on their field notes will offer more than "consult the documentation for more" advice on realted subjects. The author doesn't even offer an overview for the tools or hardware shown. You might as well print a list of hyperlinks and ask [$$$]for it. I'd like to see Sun encourage all their employees to follow the likes of Brian Wong or Adrian Cockroft or Peter van der Linden, and write treatments with real depth if they're going to write them at all. Leave the hacking to others. Anyone can publish rough-draft field notes -- why put Sun's name on that?
