Print this pageRestoring a Mirrored Volume
A mirrored volume is a volume that protects sensitive data by keeping two copies of your data on separated physical hard disks. This insures that if a hard disk failure occurs, all the data on the volume is still intact and the volume is still available for reading and writing. But your data is no longer protected by a redundant copy.
When one half of a mirrored volume is missing from the device, or has failed, you should restore the missing or failed disk as soon as possible.
Removing a Mirror
Removing a mirror does not destroy the entire volume, but only one of the redundant copies.
To remove a mirrored volume that you no longer want or need, see Remove a Mirror.
Mirror rebuilding when one of the disks has been removed, then reconnected
If one disk containing a volume mirror is disconnected, mirroring is interrupted. Reconnecting the same disk does not cause the mirror to completely rebuild. Once that same disk is reconnected to the HP Media Vault, Click the FIX button to begin the rebuild. Please be aware that while this rebuilding operation is taking place, your data is not protected with a redundant copy. Also be aware that the mirror rebuild may take many hours.
Mirror restoration when a disk (other than the SYSTEM disk) has failed
When a disk (other than the SYSTEM disk) for a mirrored volume fails, the HP Media Vault raises a system tray alert that warns you of the loss of data redundancy. To restore the device to the same level of protection, you must remove the failed hard disk and replace it with a new, working disk. However, the device does not presume that the new disk was attached to recreate the missing half.
