View source for Compaq Proliant Raid Array Howto

==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
