Unfortunately, while ILO is great at identifying the defective drive, it has no ability to enable the UID on the drive, and given that this unit is at a remote site, we had no way of knowing in advanced if the fault light was actually turn on for this drive before the HPE field engineering arrived to swap the drive.

When you create virtual drives in hardware mode, you must use only this type of proprietary controller or some compatible of the same company.

more platform independent when using software RAID / device mapper devices.

not using the cache (RAM) of the controller, so it may lower the risk of data loss caused by power outages.

You may have more features in the created logical device (or file system) – caching or managing the disks and so on
