[plug] Good RAID Howto

[Ben Jensz]

So are you running RAID5 or RAID1 with a hot spare?  If you're running 
RAID5 you should have approximately 73Gb of space with 3x 36Gb drives in 
RAID5, or if you're running RAID1 with a hot spare then you'd only have 
36Gb.

Look up the Global Array Manager (GAM) software on LSI Logic's web site 
for the MegaRAID card you've got and install that.  You'll have to 
install the server software for Linux on the box and run the client 
software to connect to the server on a Windows machine as there isn't a 
client for Linux.

But from there you can check out the current status and setup of 
physical drives on the RAID controller without having to reboot the 
box.  You should be able to see the additional drives attached to the 
controller that you've added as well.
