[techtalk] installing RAID controller on existing RedHat 6.2 system

[Naomi Hospodarsky]

hey folks,

Anyone have any tips regarding taking an existing RedHat 6.2 server and 
adding a RAID controller to it?
I've got the driver loading (I think) but when I boot, I only see my 
original disk. How do I tell RH that there's a whole new giant space that 
it can use now?
I can't seem to find any reference that the system is acknowledging the new 
array...

Or do I have to reinstall everything??


I've never done RAID on Linux before....at least not to a pre-existing 
system...
If it matters, I've got the Adaptec 2100s PCI controller.
  Anyway, any tips at this current too-much-coffee-woman hour would be much 
appreciated....

befuddled,

Naomi
