Change the mirror status

Change the mirror status

You can make the following two changes to the status of a mirror chunk:

Change a mirror chunk from online to down
Change a mirror chunk from down to recovery

You can take down or restore a chunk only if it is part of a mirrored pair. You can take down either the primary chunk or the mirror chunk, as long as the other chunk in the pair is online.

For information about how to determine the status of a chunk, see Monitor disk usage.
