Creating Mirrored Disks

This option creates a mirror or duplication of an existing disk on the HP Media Vault.

When you save files to a mirrored disk, 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 total storage space of 200GB, not 400GB.

Note
 

When creating a mirror, you must use a blank hard disk that is the same size or larger than the source disk you want to mirror.

 

Data on a mirrored disk is safe unless both disks fail at the same time. If one hard disk fails, the server administers a warning. The failed hard disk should be replaced immediately.

To create a mirror

You must insert a new internal disk that is the same size or larger than the existing disk into your HP Media Vault prior to completing this procedure.

  1. At the computer, click Start, All Programs, HP Media Vault, and then Control Center.
  2. On the Tools tab, click Customize HP Media Vault.
  3. You are prompted for an administrator name and password if you set one up. For additional information, see Editing System Settings.
  4. On the Disks tab, locate the disk you want to mirror.
  5. Click Add.
  6. A message displays giving you the option to expand the current storage space or to make the storage space redundant.
  7. Click Allocate disk to make current storage mirrored (protects current storage, RAID 1).
  8. Click Accept.
  9. This process may take several hours before the disk is completely mirrored. You can continue to use the server during this time.
    10. Note
     

    If the expansion disk does not have enough space, the option to create a mirror is grayed out.

    Note
     

    The server does not automatically show the progress of the mirroring. To view the progress, click Refresh. The progress status is indicated under Status on the Disk Settings page.
