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 an aggregate or traditional volume that is being created and Data ONTAP needs to zero out one or more of the disks targeted to the aggregate or traditional 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- Out-of-date--The plex contents are out of date and the other plex of the aggregate or traditional volume has failed.
- Resyncing--The plex contents are being resynchronized with the contents of the other plex of the aggregate or traditional volume.

Changing the plex state

Data ONTAP specifies the state of a plex as resyncing when synchronizing the two plexes of a mirrored aggregate or traditional volume. For example, when you create a mirrored aggregate or traditional volume by adding a plex to an existing unmirrored aggregate or traditional 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.

To change the state of a plex, complete the following step.

Step	Action
1	Enter the following command: { aggr \| vol } online \| offline plexname
