How do I recover a RAID Set

The “RESCUE” function can recover the missing RAID set information.

  • The RAID controller uses the time as the RAID set signature.
  • The RAID set may have different time after the RAID set is recovered.

The “SIGANT” function can regenerate the signature for the RAID set.

Rescue Volume only if Areca  RAID Set Hierarchy page is listing the RAIDSET but Volume state is missing or indicating error as seen below

Check Windows Disk Management Utility if the Volume was recognized,  if it prompts for DISK initialize then there was never a volume defined for that array or it was deleted.
