I have a Snap Server 520 , the power failure occured. We have a Netvault utility running on different servers which will take backup of these server's data and write it to library in snap server and then to tape drive which we replace everyday. After Power failure whenever the backup runs the message status keeps showing as "Waiting for Media". Also when I go to Status under Netvault utility it does not shows any drive under device status . when I check the Snap server interface it says RAID Resync 49% completed. Does someone know if the drive will be unavailable while its resynching? Also how much time would it take for around 3TB to completed resynching , its already 49% complete now. Also if someone has any experience with Netvault and If I can do anthing to troubleshoot this issue from there that would be helpful. Appreciate the help and time.
