SHR-2 Crashed. System says 3 failed HDD, only 2 red.

[jimpa]

Hi all!
SHR-2 Crashed 3 failed HDD, please help, only 2 disks report crashed in red color but I have still 2 disks initiated but I can't use "Manage" button to repair.
I have SHR-2 with 2 failing disk but I see that I got 3 disks with problems..... How can I get back my data.

in Putty the MD2 seems quiet ok I just need 80-90% of the data back because is so much.

I need someone that knows this in detail and ask also for more data if needed from me.

It seems that I need assistance due to mange button can't be used (it greyed) even I have 2 disks available 
for mending the volume. Anyway I need help to fix the volume. It seems that \md2 is the raid that has the info 
back as I need.
Check the picture.
I need one more disk up and running to get the volume intact again. That is the help I need.
