This page is meant for a short description of all those little emergencies that will make an inexperienced sysadmin panic, where anybody who's met them before will go "shrug, this is a cynch".

Hardware Troubleshooting
Replacement Controller Cards
If you think your controller is faulty, and have replaced it with a spare you had lying around, make sure the controller and drives are compatible! Some SATA-II controllers cannot handle drives over 2TB.
Boot Problems
Centos Emergency Mode
Centos (and presumably other distros) has an emergency mode. Typically such modes suppress module loading, ignore fstab, and a whole host of other potentially problematic features.
Of course, this also will suppress a load of features you want like bringing up your raid array. Try manually doing all the features you expect boot to do for you.
