Re: RAID configuration

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

Whe you select to start RAID what error do you get? You should be able 
to start RAID whether the drives are configured or not. There are only a 
few things that stop you from starting RAID:
1) No RAID card (DUH!)
2) Not enough drives that are not RADIed already or MIRROREd of the same 
size on the RAID card,
3) Not enough free space on the drives. If you have 4 drives and they 
are all part of the ASP then they need to be at aximum 75% full to allow 
for the space lost to RAID striping.
4) the drives are write protected (They have a letter 'H' in their 
name)  In this case they need to be formatted first through the problem 
recovery menu.
