Due to built in fault tolerance, raid disk configurations are very common in organizations to handle the increased use of data. See our technical resouces to under more about raid disk configuration such as RAID 0, RAID 1, RAID 3 and RAID 5.
Ironically, due to lack of backup and belief that the raid array should not fail, raid disks failures happen to be one of the more common types of enterprise storage failure despite the built-in redundancy.
In case of raid disk failure, you should refrain from doing "rebuild" or hard disk swapping in the hope to bring back the raid volume. Rebuild is normally possible only if the raid array is still running in degraded mode. Frequently, due to controller failure, logical corruption of VRAM resulting in loss of logical volume, a hasty rebuild or reinitialization may result in total loss of data.
