Hello everyone,
today I had to upgrade the firmware of my 3ware RAID controller in order to start my - quite old - server with ESXi 4.1. Before this the server wasn't starting at all from one day to another.
Now I face two issues which I am not sure if they existed before.
I have a RAID 10 - configuration (please see attachment) with 6 disks.
Am I right that disk 4 is missing at all and disk 3 has a failure an should be replaced?
Thanks for your help in interpreting the picture!
Daniel
Ouch Raid 5 with a double failure...
You should really reach out to a data recovery service at this point, as you could damage your chances for getting anything back.
There are a few data recovery people on this forum and there is a KB I'll attach below.
Ontrack offers a free data recovery assessment, I think drive savers also does the same.
Kind regards,
Fouad

is your storage accessible ?
i wonder what part of the raid the 2 missing disks have? are they spare disks?
if you have 3 mirror sets in your raid10 then the storage cant be accessible anymore
the attachment couldnt be opened.
also look into the controller bios and verify the configuration - there you should see how the raid is defined and see errors of the disks
is the storage acessible ?
Will check the controller bios asap.
Today I just had a smart failure - before I upgraded controller firmware.
Also, the storage is acessible now and runs two VMs (as it did the last years).
I add the attachment again and a second one showing the smart failure - these messages were gone later, after firmware update
Edit: seems to be a RAID 50

Thanks for your opinion ... I think I will build or buy a new server. The are SAS drives impossible to find for a decent price.
Another option may be to purchase an external SAN/NAS solution.
Then you could have multiple servers attached to the same "shared" storage. This would give you the ability to have extra compute/compute redundancy, and most modern (even low end) SAN/NAS options have data integrity alerting and usually some form of upgrade support.
I hope you have a good backup of the data on the array and that your recovery process isn't painful.
In any case I would export the VM's you have access too as an ovf/ova as soon as possible in case the RAID drops off again.
Kind regards,
Fouad
