how do I use the working hdds / arrays from a dead ml350 g5 server to salvage data?

Hi experts,
I was given a ml350 g5 server, with what seem to be a dead motherboard.
it won't boot (no screen) - "internal" led blinkind red . (CPU1 led is amber, tried to replace CPU, same deal)

esxi 5.0 was installed on that server, with 3 VM.
I'm fairly sure the hdds / arrays are intact (mirror only, no raid5)
I tried to move one of the Array into a ml350 G6, but it was not detected (labelled as unassociated devices)

what can I do to get those data back?
the ideal scenario would be to mount the vmfs partition, copy the VMs then restart from there.
I guess fixing the server would be an option as well, if possible at all.

thanks!

You need to insert the disks in the correct order in another HP Server, with Smart Array, and it should read in the array configs from the disks, and assign a logical drive.

If you don't have another smartarray, you can use ANY non-raid controller & buy a copy of runtime.org raid reconstructor.  Then you can reassemble on anything,

I have tried that with a ml350 G6,
it did not work, gave me an error "part of a logical unit that is not supported"

I will try with another ml350 G5 before moving to data recovery,

It should just be a straight Linux partition that you can attach any SAS or SATA controller to and copy you data that way.

I believe vmware should have a bootable recovery disk that you can run in repair mode.

Use at your own risk.

Maybe the message was in fact "part of a logical drive that is not supported by the current configuration"?

Did you remove the current drives from the replacement server first before inserting the two disks from the failed server? If so and still the problem then you should try again without the cache module.

I was able to move the arrays into the other ml350 G5 with the exact same controller which picked up the whole configuration.
from there, it was much easier than I thought,
just ran into some minors esxi issues.. I can now backup the VMs.

thanks for the replies. : )
