The plex kernel state indicates the accessibility of the plex to the volume driver which monitors it.
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:
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.
The plex is offline and cannot be accessed.
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. If a plex is sparse, this is indicated by the SPARSE
modifier being displayed in the output from the vxprint -t
command.
