We have identified two separate disks that have failed simultaneously. 1B-C3 and 16C-C5 in symmetrix.
Unfortunately they are both in the same raid group. Raid-5 (7+1).
We are currently unable to initiate a replacement of either Drive, because of potential data loss on the other drive.

Total 5 devices affected. These are assigned to different servers.

Any procedure to replace the disks without data loss. I really appreciate your help.
