This option creates a mirror of an existing volume or source volume on the HP Media Vault. A volume is a portion of one or more hard disks configured to store data. A mirror duplicates the source volume on another hard disk. For more information on mirroring, see Understanding disk mirrors and concatenated disks.

When you save files to a mirrored volume, your files are saved to both hard disks. The end result is that half the total amount of space is available to store your files. For example, two 200GB drives mirrored together result in a mirrored volume of 200GB, not 400GB.

To create a mirror, you must select unallocated space on another hard disk. The unallocated space has to be the same size or larger than the source volume you want to mirror. If all of your space is allocated, you might be able to create unallocated space by resizing a volume. (To resize volumes, see Modify a volume.)

  • Data on a mirror volume is safe unless both disks fail at the same time. If one hard disk fails, the media vault will administer a warning. The failed hard disk should be replaced immediately.

To access the Disk Settings screen:

  • Double-click the HP Media Vault icon on your desktop.
  • Click Customize your HP Media Vault’s settings.
  • If the Welcome Screen appears, click Configure Device.
  • Click the Disk Settings tab.

To create a mirror:

  1. Select a volume by clicking the Select a Volume drop-down list.
  2. Click Create a Mirror.
  3. A screen opens displaying the volume you have chosen. For example: You have chosen Volume1 to mirror.
  4. To select a hard disk that you want to become a mirror of the selected volume, click the Disk assignment drop-down list.
  5. Click Accept or Cancel. If you click Cancel, a mirror will not be created.
  • Creating a mirrored volume can take several hours.
