Removing a Mirror

 

Removing a mirror from a volume removes or destroys the data from the selected mirror and leaves the other mirror intact. After you remove a mirror, the
space on the disk used by the removed mirrored volume becomes unallocated space. The remaining (no longer mirrored) volume becomes a simple volume on
the disk.

 

To remove a mirror, perform the following steps:

1.

 

Launch Array Manager.

 

See "

Launching Array Manager From the NAS Manager

" in this section of the guide.

Breaking a Mirror

 

Breaking a mirror creates two simple volumes with individual drive letters. Each volume contains the data on the mirror at the time the mirror was broken. The
data is no longer redundant, but it remains intact.

 

To break a mirror, perform the following steps:

1.
