A brief description of the current problem and my solutions to this problem. (I'm wanting peoples opinions and experience on this)
We have a HP ML370 server that has a Smart Array 641 RAID controller with three 72.8GB Ultra 320 SCSI hard disks setup in a hardware RAID-5 array.
We have a temporarilly spare HP ML350 server that has very similar hardware.
Space on the ML370 is rapidly running out, so i've ordered three more 72.8GB SCSI hard disks.
We need to add more space to the current partition, as far as I see it I have two options.
1. Add the three new hard disks and create a second RAID-5 array, in windows extend the dynamic disk to include the new drive. (spanning the two partitions)
2. Using Symantec Ghost Corp 8, Ghost the SCSI drive (from my understanding the smart array 641 makes the raid array appear as a single drive to the os). Once ghosted delete the current RAID setup, add the three new drives and create a new six drive RAID-5 array. Ghost the image onto the new raid array and voila we've got a nice single raid array setup.
I prefer the second option, partly because i'd prefer not to use the extend bit and also with the extra drives i'll be able to set the sixth drive as a spare drive. (I didn't setup this server originally)
On Monday i'll be doing the second option as a dry run on the ML350, can I please have peoples opinions on this and advice.
Up to this point i've only ever ghosted workstations, never a server.
