NOTE No user intervention is required to set these states; they are maintained
internally. On a system that is operating properly, all plexes are enabled.
The following plex kernel states are defined:
DETACHED Plex Kernel State
Maintenance is being performed on the plex. Any write request to the
volume is not reflected in the plex. A read request from the volume is not
satisfied from the plex. Plex operations and ioctl function calls are
accepted.
DISABLED Plex Kernel State
The plex is offline and cannot be accessed.
ENABLED Plex Kernel State
The plex is online. A write request to the volume is reflected in the plex.
A read request from the volume is satisfied from the plex.
Attaching and Associating Plexes
A plex becomes a participating plex for a volume by attaching it to a
volume. (Attaching a plex associates it with the volume and enables the
plex for use.) To attach a plex to an existing volume, use the following
command:
# vxplex [-g diskgroup] att volume plex
For example, to attach a plex named vol01-02 to a volume named vol01,
use the following command:
# vxplex att vol01 vol01-02
If the volume does not already exist, a plex (or multiple plexes) can be
associated with the volume when it is created using the following
command:
