Removing a Mirror From a Volume
CAUTION Removing a mirror can result in loss of data redundancy.
The Mirror Remove procedure removes a mirror from its volume. This
procedure breaks the link between the mirror and its volume and
returns the mirror disk space to the free space pool for reuse. You can
remove an extra mirror from a volume to make the underlying disk space
available for use elsewhere. However, this may leave the volume
unmirrored and unprotected against disk failure.
To remove a mirror from a volume
Step 1. Select the volume that contains the mirror to be removed.
Step 2. Choose Actions > Mirror > Remove.
Step 3. Complete the Remove Mirror dialog box as follows:
Volume Name: If the correct volume name does not already
display in this field, enter the volume name or
select the volume from the drop-down menu.
Removal Method: Specify the mirrors and/or number of mirrors
to be removed:
• To specify how many mirrors should be
removed, select By Quantity/Disk. Enter
the number of mirrors to be removed in the
Mirror quantity field.
• To specify the disks on which mirrors
should be preserved, select By
quantity/disk.
• Specify the names of disks or mirrors to be
removed from the list of available disks or
mirrors.
