When two hard disks fail in a raid5 array the data is lost. You can not recover it.

If you have backups, look into restoring from them.

Otherwise see if the two hard disks that are marked as failed can be reseated and start running again. Or reboot the server and hope that the disks get reviced.

Hello!

If both the disks are totally broken (does not spin, hangs at startup, has broken heads etc) the recovery is not possible.

If one just has some (not many) bad blocks you have a chance to recover a part of data. Some data will be corrupted

It will not be easy. If you do not have an experience it will be better to seek for "HDD data recovery" service near you.
