Hi Dhana,

You might want to make sure to follow the steps mentioend at this link: Ensuring RAID Pairs Rebuild Successfully

Further, if you are using recovery CD, please make sure to run option 7 more than once and then option 8 to install the image on box.

  1. Configure Network

  2. Manufacture flash

  3. Install flash cookie

  4. Install flash image from network

  5. Install flash image from cdrom

  6. Install flash image from disk

  7. Recreate RAID device (WAE-674/7341/7371 only)

  8. Wipe out disks and install .bin image

  9. Exit (Eject and reboot)

Looks like this may be the RAID controller failure. Please open a TAC case to RMA the device.
