Adding drives to a RAID 5
Posted on 2006-07-21
I have a server with 4 drives in a RAID 5 array. The hardware is: (4) 36 GB Seagate SCSI drives and an Adaptec 2000S controller. I'm running Windows 2000 Server SP4. I want to add (2) 36 GB hard drives to the RAID 5. After replacing one of the drives that had failed, I installed the 5th hard drive. I used the Adaptec Storage Manager to configure the new drive. It shows as part of the raid. When I go into Disk Management (in Windows). I see the C drive (102.53 GB) and right next to it, I see an Unallocated 34.20 GB. I wasn't excited about Extending the original C drive to the new drive because it seems as if that would be controlled by software rather than hardware. But, I tried it anyways and I got this message, "The selected volume was originally created on a basic disk and cannot be extended. Only volumes originally created on dynamic disks can be extended." I'm not sure what the best path to take from here. I've heard techs say that they've used Ghost and imaged the RAID 5; completely rebuilt the RAID and then reimage the drives. Then I've heard Symantec say that they don't recommend or support it (probably trying to cover themselves). I've searched around the Internet for a DOS driver for my Adaptec 2000S and can only find a Windows 98 driver. So, I don't even know if the Ghost method will work for me if I can't get a DOS driver. What is the best way to make this work? Thanks!
