Switch disk in servers without losing content

[Stig Sand]

Hi,

Need to change server hardware on a couple of servers, and wanted to just change the disks, and hopefully it would start up on the new server.
But that is not the case :(

I took out 2 disk (Raid1) from a UCS B200M3, and put it in a UCS B200M2, but everything was gone at the disks when I startet the server.
There is no Scrub Policy applied on any of the servers.

The way I did it, was that I turned off 2 servers, (B200M3 - Windows and B200M2 - ESXi) and disassociated Service Profile. Then I swapped the disks and associated Services Profiles again (Now: B200M3 - ESXi and B200M2 - Windows)

None of the servers was functional when I started them again.

If any understand what I have tried to do, please help, if there is a way to do this.

Regards

Stig

Let's go through the details to see if I can help:

"I took out 2 disk (Raid1) from a UCS B200M3, and put it in a UCS B200M2, but everything was gone at the disks when I startet the server."

*Did you install the disks in the same order? meaning disk on the left was still the one on the left when you put it in the new server?

*Did you check the new server's service profile and made sure you were not using another RAID level?

With SAN boot you would accomplish this a lot easier just by changing targets in the Service profiles (assuming zoning and LUN masking is properly set)

Hi, and thanks for you reply.
I am 99 % sure that I put left disk in the left slot at the new server, and right disk in the right slot.

And I only have one Disk Config Policy that I use for all my Service Profiles, and it have Raid1.

We haven't started to use SAN boot yet.

Hi Stig,

The reason you lost the data of your hard disk in because you moved them between an M2 an M3 blade. These blades do not use the same raid controller so it is expected that you will lose the data. Not only that, as it is explained in the installation guide below (Go to the hard disk installation section) raid migration between M1, M2 and M3 blades is not supported. Please let me know if you have any questions.

Good catch Manuel, I even copied pasted it and never saw they were different models.
