Enterprise datacenters require 100% uptime from their servers, and this book shows you how to achieve just that with your Sun Solaris boot disks, one step at a time. You'll find qcookbook recipesq for properly configuring system disks and setting up hot-swapping so your Sun servers won't need to reboot -- even if the system disk fails. Adhering to a strict definition of high availability, Sun expert Jeannie Johnstone Kobert reviews every key Solaris high availability technique, covering both hardware and software. Start by configuring the Sun StorEdge A5000 as an external system disk using Solstice DiskSuite; review optimal configurations and components; understand boot disk risk factors, and learn how to mitigate them. Learn how to set up mirroring using the Sun StorEdge A5000 and Sun Enterprise Volume Manager, and master essential recovery and hot relocation techniques. Kobert introduces Unipak, Sun's low-end solution for high availability, presenting a previously undocumented scenario for boot/root/swap that utilizes a dedicated disk as the swap device. Finally, learn how to configure your boot disk to use alternate pathing in conjunction with Sun Enterprise Volume Manager. A detailed appendix provides equivalent command line options for the GUI steps covered throughout the book. From start to finish, these solutions offer maximum availability -- without compromising simplicity, flexibility, or scalability.Configuring Boot/root/swap Jeannie Johnstone Kobert ...
