[TriLUG] Raid gurus?

[WA Brown]

I have read some about Raid. Please explain what happens with Raid 
1(mirroring). Does it do this automatically or something has to be done for 
the working drive to take over? What would happen if I disconected one of 
the drives in a Raid1 config? Would the other drive automatically take over? 
After the disk is put back in will the Raid update the drive to match the 
first one?Automatically?
