Move RAID-1 Array from HP DL140 G3 to another server

Hi,

I have 2 alike servers, both HP DL140 G3 with build in RAID controllers.
The difference is this :
Exchange Server: has 2*72 GB SATA disks, '
Sharepoint Server: has 2*250Gb SATA disk.
They are both configured in RAID1.

My Exchange server has a faulty motherboard and besides from it having power it does not boot or show anything on my monitor.
To rescue the data I need to access the RAID.
How can I get access to the RAID? I would like to try to move the drives to my other server and boot up, but will that work? It has a LSI SAS Build in controller, but I cannot see any choices to read or write RAID configuration to the drives (like I am used to on IBM servers).

Hope some one can help since the backups has been lost as well.....

I would think that you could just swap the drives out and boot the server as regular. I know I have done this in the past with like dell 2950s. We had a similar situation where a unit came faulty from the factory. We simply swapped the drives into the new server and everythign worked as normal.

RAID information is written on the disks so if you have two identical servers, then you can remove the drives from one server and place them into the other server and boot hapily as it will recognise the RAID configuration from the disks.
As long as the RAID controllers are the same, this won't present you with a problem.

Thank you for your comments xxdcmast and alanhardisty.

I am also thinking it would work, but am not sure. I have tried this on many IBM servers with LSI controlelrs and then I had to manually choose to read the configuration from the drives instead of using the configuration on the controller.
On the controller on my HP DL140 servers there is not very many configuration choices, it seems to be a very simple raid controller.

Have any of you tried this on the controllers on the DL140 servers?

Are they both the same generation of DL140? (G1 / G2 / G3)
What are the part codes from the server?  Should look something like 867431-B21 (format-wise, not number-wise).

If you can advise the above - I can tell you if the controllers are the same and if it should work.

I will not be able to check part codes before monday, but I know they are both G3 and bougth together so I would be very surpriced if they are different part codes. I am pretty sure that the controllers are the same, but that does not mean that it will automatically boot any raid array created on a identucal controller?

I am trying to avoid the try and fail method so it would really be nice if this has been tested before :-)

I don't have a DL140 but have a ML350 G3 and a ML350 G6 and I have used HP hardware for the past 15 years.
According the the HP World-Wide specs, there are 6 different types of controllers that could be in the servers, so unless the models are identical, the controllers could be different and thus I would not recommend doing anything until you know for sure.
http://h18000.www1.hp.com/products/quickspecs/12509_div/12509_div.HTML
I have replaced several RAID controllers that have failed (one in my ML350 G3) and the server sprang back into life once an identical replacement was installed.  So, as long as your controllers are identical, you can swap the drives over without any fear of losing anything.
Make sure the controller firmware is similar on both servers as this can cause issues with not recognising the RAID information on the drives properly.
Of course, to be on the safe side, you should ideally image the drives before you do anything, but I suspect that this is not going to be a viable option.

Unfortunately the 100 series aren't like the 300 and above series.

The 300 series is in another class, but I will try anyway. Thank you for the tip about the firmware and and so, but my problem is that the server, where my 72 B drives I want to move, is dead. No way I can check it, but surely I will upgrade the firmware on the working server to the latest version... or should I?

Alan HardistyCommented:
As long as the firmware is the same or newer you should be fine, so upgrading to the latest firmware will be fine.

I will try to move the disks monday and will psot a comment when it is done. Thank you all for your comments :)

No problems. Hope it goes as smoothly as we all anticipate.

I wanted to top points to alanhardisty, his comments and solution was the most correct one

No problems from me - I will request attention and get the question re-opened, then you can close the question again.

Just moving the drives from the defect server to the identical working was working fine. To be more spesific I also had to open the LSI RAID configuration at POST to set the discovered RAID as active.
Then the server booted as it should :-)

Thank you all for comments
