Posted on 2005-04-11

Hi All,
I have just taken over a single server network running W2k.  Here is the Configuration:
Physical Disk 1
OS partion- 6 GB total
Programs partition 12 GB Total

Physical Disk 2
Data Drive 18 GB

I want to install a RAID 5 array with 36 GB hard drives (3) and one hot spare.  I am looking for steps that would outline teh easiest way to migrate everything. I am familar with RAID, so I don't need the mini steps.  But I was wondering what is the easiest way.  
Any suggestions would be greatly appreciated.

    If you only want to have your data on the RAID drive then you only need to install the Raid card and configure your drives and at the end copy your data from the existing disk, then you can decomission the existing data drive. If you want to include the OS then I would not do that, since it is usually better to keep the system away from the data. I see though that you seem to have two 18 GB disks. I would then install the OS on RAID 1 if your card allows you to have two sets of RAID. You would of course have to save your data and programs on another media before you install the drives since it will erase everything on the drives when adding them to a set.

    I want to include the OS in the RAID 5 implementation.  However, I do not want to have two separate RAID arrays.  I would like to have them on the same RAID array with 3 new 36 GB drives.  What is the easiest way to migrate the OS and the Data?

    If you want to have all on the same RAID then just make 2 good backups of all your present data and then install your new hardware then reinstall what you need to be able to restore your backup and then you should be up and running
