Migrating RAID from one server to another (AP)

Hypothetical question, we have two identical HP ProLiant servers with 2 RAID1 HDD's in (running Windows Server 2003)

It looks like we have a MB failure in one of them, is it possible to swap the two RAID1 HDD's into the new server and boot it back up second server with the new HDD's in and let it carry on doing what it was doing?

    Accepted Solution

    Assuming it is a proper ProLiant with a Smart Array controller then they are fully backwards compatible meaning a controller of the current generation or a future generation will read the configuration from the disks and be able to read the data, they're also partially forwards compatible meaning an older generation controller will be able to read the disks from a current or future generation.

    As you're talking about the same generation server which will have the same generation controller there will be no problems, it will boot and run but the networking will have to be cleaned up since the MAC addresses will be different.

    Oops - "older generation controller will be able to read the disks from a current or future generation." should say "older generation controller will be able to read the disks from a current or future generation so long as no new features have been used." An example of that limitation is the latest controllers support disks greater than 2 TiB but previous ones don't.
