Ghosting a hardware RAID-5 array (HP ML370, Smart Array 641, Win 2k Server)

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.

I don't think it's going to work.  Ghost usually knows if the OS is a server and won't run.  I think you'll be better off and greater chance of success to use option 1.

This is the corporate edition, not the normal Norton version.

Does it say Server?  Corporate or not, you usually need an edition that supports server, and I'm fairly certain simply a "corporate" edition isn't going to cut it (I could be wrong).

Ghosting the server is done the same way that the PC's are done.
Setup your server as you need it (OS,apps etc.)
Install Ghost on another machine and connect that machine to a hub. Give it an IP address like
10.120.1.2
Create you need to download the DOS drivers for the ML370 they are on the HP website.
On the so called Ghost Server. Create a ghost boot floppy with these drivers on. then open the floppy and i think there is a net folder in there there is a file like tcp.cfg (maybe wrong this is off memory)
but is a filename that you can associate with an IP
Edit this file to be 10.120.1.3 for example
Configure the Ghost "Server" to accept clients ("Dump from Client") and then
Connect the ML370 to the same hub as above and
Boot to the Floppy on the ML370 and go into Ghost and select Multicast.
This should dump the image on to the Image Server

To dump  on the Server set to Load to CLients on the Ghose Server!

P.s not sure what Leew is on about! Corporate edition will work (there is only the Corp and standard editions)

See http://www.experts-exchange.com/Storage/Q_21229423.html

Do you have more slots for drives available on the server?  If yes be sure you backup first then follow the instructions in the RAID management software to add the extra drives.

It should work without any problems. I've not tried it with Ghost but have done it with Altiris and while it was slow it did work. Option 2 is the way to go.

I would also suggest not using a Hub but use a crossover cable instead. You will be shifting a lot of data around and if that hits your network your users might be a bit annoyed. And why does my text not wrap?

As RDAdams says - back it up before you start.

Why not use the Hub i use it to image about 8 Servers at once!
All you do is put the Client counts up to 8 (or however many your hub can accomodate)

Though crossover cable will work! for one to one images

I meant for the hub to be off the network. Actually our Ghost Server has a image Nic anda LAN nic for imaging and access to the live network

That way our images dont affect network traffic

A few notes:

Yesterday I did the Ghosting test with the spare ML350 dual Xeon server and it imaged and re-imaged fine.

I started ghosting the ML370 but since the estimated time was at 8 hours I've decided to postpone it until the weekend.
