IBM DS3400 2 failed drives in a raid 5 array

We have 12 drives in a raid 5 array and we lost two drives.  The recovery GURU is showing an Incomplete array. We have replaced both drives but they are showing unassigned. I assume we would need to assign them to the old array and reconstruct them. Does anyone know the correct script to do this?

You have 100% data loss with 2 failed disks.  Turn off everything and contact a data recovery professional and take them all the drives.  (Be prepared for minimum cost of $5000)  RAID5 can only tolerate a single HDD failure.


Hopefully you have a backup you can restore from. A 12 drive raid 5 group is very risky, and you just got burned. The probability of two drives failing increases as the drive count increases. Raid 10 or 6 are much safer.

The drives are reaching the end of their life so this is to be expected. We will switch over to a new storage device.
