Changing the state of a plex

Plex states

A plex can be in one of the following states:

Offline--The plex is not available for read or write access.
Online--The plex is available for read or write access and the contents of the plex are current. An online plex can be in the following states:
- Active--The plex is available for use.
- Adding disks--Data ONTAP is adding disks to the RAID group or groups of the plex.
- Empty--The plex is part of a volume that is being created and Data ONTAP needs to zero out one or more of the disks targeted to the volume before adding the disks to the plex.
- Failed--One or more of the RAID groups in the plex failed.
- Inactive--The plex is not available for use.
- Normal--All RAID groups in the plex are functional.
- Out-of-date--The plex contents are out of date and the other plex of the volume has failed.
- Resyncing--The plex contents are being resynchronized with the contents of the other plex of the volume.

Changing the plex state

Data ONTAP changes the state of a plex to resyncing when synchronizing the two plexes of a mirrored volume. For example, when you create a mirrored volume by adding a plex to an existing unmirrored volume, Data ONTAP puts the added plex in a resyncing state.

Data ONTAP allows you to change the state of a plex from offline to online and from online to offline.
