RFC - Upgrading from Raid 0 to Raid 1 on an HP-DL360 G4

Hello Experts,

We have currently running a DL360 G4 server with two disks of 36GB in Raid 0. We bought two new 140GB disks and would like to upgrade to Raid 1.

The way I thought to go about it is to:
- Create a full disk image to a second server
- Replace the disks
- Reconfigure the array using HP SMartStart
- Copy back the disk image to the newly created Raid 1 array

First of all I would like to know whether this wil work. Will the machine boot correctly if I just copy the image, or are there any other steps I need to take.

Secondly I would like your advice on which imaging tool to use. Preferably one that supports network transfer, but I could also use a USB-disk if needed.

I suppose Acronis or Symantect would do the trick, but their licensing prices are prohibitive for our small SME, especially given the fact that we will only need to do it once.

I found r-tools (www.r-tt.com) that offers a 15-day fully functional trial, but never heard of them before so I don't know whether it will work.

Any thoughts?

You MAY be able to do an in-place migration.
I don't know what model of smart-array you have, so best to go to the HP support site and pull up the manual, but at least some of them support in-place.  I.e, just pop in the new disks, tell it to convert the RAID0 to RAID1, RAID10, whatever .. and it does it.

So this is a rare situation where it may be worth it to read the manual ;)
Also, no matter what, even if it says upgrade in-place is OK, best practice is to:
1. backup data
2. upgrade firmware, drivers, and absolutely make sure you have latest version of ACU.
(Note, the reason why this works is that the smartarray controllers JBOD/RAID0 mode actually writes metadata at beginning of all disks no matter what, just for such situations.

P.S.  I am assuming you are converting from a 2-disk RAID0, to a 4-disk RAID10, not a pair of RAID1s.

Everybody, thanks for your quick and helpful responses.

dlethe, unfortunately your suggestion won't work as the DL360 G4 only has bays for two disks. However, the upside from switching the disks is that, if I can't get the new disks working I simply put back the old ones and we're back on-line in no time flat :-)

By the looks of it, bootit-ng does exactely what I need and the price is very reasonable. If this doesn't work, we'll try Acronis. That's to say, the trial version, as 768.00€  is a ridiculous price for a back-up software.
