Table 6-2
Plex condition flags (continued)
DescriptionCondition flag
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out-of-date with respect to the volume.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.
RECOVER
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.
REMOVED
Plex kernel states
The plex kernel state indicates the accessibility of the plex to the volume driver
which monitors it.
No user intervention is required to set these states; they are maintained internally.
On a system that is operating properly, all plexes are enabled.
Table 6-3 shows the possible plex kernel states.
Table 6-3
Plex kernel states
DescriptionKernel 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.
DETACHED
The plex is offline and cannot be accessed.DISABLED
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.
ENABLED
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
