Introduction
WORK IN PROGRESS
This HOWTO should provide help for anyone using Compaq Proliant Server that uses the compaq removabale drives (usually 2 or more of these bays in a server or between 7 and 14 in a raid array rack mount).
Will contain subsections for installing for the first time, installing the array if you already use it as an scsi device (without data loss - nice n easy when ya have a cluster) and also replacing a drive on a fail and testing.
Requirements
- Comaq Proliant Server
- Sort of goes without saying
- Compaq Smart Start CD
- Versions from 5.1 onwards (Smart Start is backward compatable with previous versions at the time of writing)
limitations
Only Raid 0, Raid 1 and Raid 5 will be discussed in this HOWTO
Please note that data recovery only happens in Raid 1 and Raid 5. The unlikely event of 2 drives failing at the same time, will not be discussed in full in this HOWTO.
Basics
- tar everything up and post this on a spare machine
- reboot and run smartstart to setup your raid array(s)
- reboot and untar filesystem backup from remote machine
- recompile and install kernel with appropriate hardware raid drivers compiled in (not modules)
- reinstall/resetup grub
- reboot and enjoy raid goodness
