arcserve-KB : How to rebuild Media in a RAID 5 configuration

Last Update: 2015-12-15 22:35:51 UTC

CA ARCserve Backup lets you rebuild one missing or unusable tape containing backup data in a RAID level 5 environment. Due to the architecture of RAID Level 5 (striping with parity), you cannot rebuild more than one missing or defective tape.
To rebuild RAID tape drives
1.Eject the incomplete RAID set, using the eject option from CA ARCserve Backup Device Manager (choosing   'Eject' while highlighting the RAID ejects all tapes in RAID). 
2.Insert a tape that the user wants to use as the replacement for the missing tape in one of the tape   drives. 
3.Chose Erase from the Device Manager. 
  CA ARCserve Backup erases the tape.
4.Insert the incomplete RAID set in the other tape drives and click the Rebuild toolbar button. 
  CA ARCserve Backup rebuilds the media. 
To rebuild RAID tape libraries
1.If there are no blank tapes in the library, import one tape, or erase an unused tape in the library. 
2.Choose the RAID set that you want to rebuild and click the Rebuild toolbar button. 
  CA ARCserve Backup rebuilds the media.
