Re: Adding a second RAID set



Have you booted into the RAID configuration utility and make sure you can
see the drives there? Are you using the DELL Disk Array Manager Console?
What do you see? Do you have a Dual Channel RAID Controller?

Hi

Our Dell Perc 4/Di had two disks in a RAID 1 configuration. Now we
have added two more disks and have made another RAID1 out of these
two. In Perc configuration old and new raid sets appear as two logical
drives. However when I reboot the server it says 0 logical disks
found. The only way for me is to take out the two new disks and reboot
and then the original logical disk appears and I can boot into
windows. What am I doing wrong and what is the correct way to add
another pair of disks in a RAID1 while there is another pair already
in RAID1 on Perc 4 /Di?

Many Thanks

Regards
