RAID 6 layout utilizes two different parity functions which helps a RAID 6 array survive up to double disk failure.
Despite of the fact that RAID6 is perceived to be more reliable than a RAID 5, the probability of a controller failure is the same.
So if your RAID6 fails, this will most likely be due to a controller failure.
To recover a RAID6 from a controller failure, you need to know or recover the following parameters:
You should know all these parameters to reconstuct RAID 6 successfully.
Our software ReclaiMe Free RAID Recovery (download)
can recover RAID6 configuration automatically.
See the step-by-step RAID Recovery instructions.
RAID 6 is significantly more complex than RAID 5.
Although RAID 6 should be recoverable with one or two disks missing, the implementation of ReclaiMe Free RAID Recovery
cannot work with RAID6 having missing disks.
