Transfer disk between two ESX Server (DL385)

Hi guys,

Currently, I have my ESX server (DL385) with a logical of 2 x 72GB HDD created as RAID 0. This logical drive is the VMFS datastore which contains all my VM images. Due to some maintaince required on this server, I need to transfer this 2 disks over to another DL385 also installed with ESX. Can I achieve this without data loss? Will the ESX still recognize the 2 disks as a logical drive with RAID 0?

Appreciate your advice and thanks in advance!

Wow, interesting situation.

I would never recommend raid0, unless you like recovering data from tape at some point.

That being said, I *believe* that proliant servers will recognize when raided disks are moved from one server to another, so long as the controllers are similar/same.

It's an easy test: power off your ESX server, and move the drives, and see if the new server reconizes the raid set, and boots. (you'll know at the firmware prompt - press F8 when prompted, and view the logical drive configuration)

If the disks are not recognized, move them back to the original server, and go to plan B. (migrate data)

Most, if not all Smart Array controllers store they disk configuration on the disks themselves. This allows you to freely move/migrate to different servers/storage configuration.

You should be able, like stated, power down, remove the drives, replace into other server and power up... and still have an array with 2 drives with a RAID0 Logical Drive on it.
