Plex states (continued)
DescriptionState
The vxmend off task indefinitely detaches a plex from a volume by
setting the plex state to OFFLINE. Although the detached plex
maintains its association with the volume, changes to the volume do
not update the OFFLINE plex. The plex is not updated until the plex
is put online and reattached with the vxplex att task. When this
occurs, the plex is placed in the STALE state, which causes its contents
to be recovered at the next vxvol start operation.
OFFLINE
This state indicates a snapshot plex that is being attached by the
snapstart operation. When the attach is complete, the state for the
plex is changed to SNAPDONE. If the system fails before the attach
completes, the plex and all of its subdisks are removed.
SNAPATT
This state indicates a snapshot plex that is fully attached. A plex in
this state can be turned into a snapshot volume with the vxplex
snapshot command. If the system fails before the attach completes,
the plex is dissociated from the volume.
See the vxplex(1M) manual page.
SNAPDIS
The SNAPDONE plex state indicates that a snapshot plex is ready for
a snapshot to be taken using vxassist snapshot.
SNAPDONE
The SNAPTMP plex state is used during a vxassist snapstart
operation when a snapshot is being prepared on a volume.
SNAPTMP
If there is a possibility that a plex does not have the complete and
current volume contents, that plex is placed in the STALE state. Also,
if an I/O error occurs on a plex, the kernel stops using and updating
the contents of that plex, and the plex state is set to STALE.
A vxplex att operation recovers the contents of a STALE plex from
an ACTIVE plex. Atomic copy operations copy the contents of the
volume to the STALE plexes. The system administrator can force a
plex to the STALE state with a vxplex det operation.
STALE
Setting a plex to the TEMP state eases some plex operations that
cannot occur in a truly atomic fashion. For example, attaching a plex
to an enabled volume requires copying volume contents to the plex
before it can be considered fully attached.
A utility sets the plex state to TEMP at the start of such an operation
and to an appropriate state at the end of the operation. If the system
fails for any reason, a TEMP plex state indicates that the operation is
incomplete. A later vxvol start dissociates plexes in the TEMP
state.
