Changes

In order to function, all the disks in a RAID 5 configuration must be online and healthy. If the RAID 5 set displays ''Failed Redundancy'' and the volume is listed as ''Offline'', ''Missing'' or ''Online (Errors)''there is a problem which needs to be resolved.

If the status is ''Offline'' or ''Missing'', check that the disk is connected and powered up. If the problem is resolved select ''Rescan Disks'' from the ''Actions'' menu. Once the rescan is complete right click on the problematic drive and select ''Reactivate''. All being well the drive status will change to ''Regenerating'' as the data is rebuilt using the parity information on the other drives in the array. If, once regeneration is complete , the status does not return to ''Healthy'', right click once again and select ''Regenerate Parity''.

If a disk in a RAID 5 configuration is listed as ''Failed'' or ''Online (Errors)'' repeat the above steps. If this fails the disk may be unrecoverable and will need to be replaced. To achieve this, right click on the volume on the failed disk and select ''Remove Volume'' from the popup menu. Once the volume has been removed, right click on a suitable block of unallocated space on another dynamic disk which is not already part of the RAID 5 array, has sufficient space and has a matching partition style and select ''Repair Volume''. This will rebuild the RAID 5 configuration using the space on new disk drive together with the remaining healthy disks from the original RAID 5 configuration.
