RECOVER Plex Condition
A disk corresponding to one of the disk media records was replaced, or
was reattached too late to prevent the plex from becoming out-of-date
with respect to the volume. The plex required complete recovery from
another plex in the volume to synchronize its contents.
REMOVED Plex Condition
Set in the disk media record when one of the subdisks associated with
the plex is removed. The plex cannot be used until this condition is fixed,
or the affected subdisk is dissociated.
Plex Kernel States
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:
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.
