Displaying plex information
IOFAIL plex condition
The plex was detached as a result of an I/O failure detected during normal volume I/O.
The plex is out-of-date with respect to the volume, and in need of complete recovery.
However, this condition also indicates a likelihood that one of the disks in the system
should be replaced.
NODAREC plex condition
No physical disk was found for one of the subdisks in the plex. This implies either that the
physical disk failed, making it unrecognizable, or that the physical disk is no longer
attached through a known access path. The plex cannot be used until this condition is
fixed, or the affected subdisk is dissociated.
NODEVICE plex condition
A physical device could not be found corresponding to the disk ID in the disk media
record for one of the subdisks associated with the plex. The plex cannot be used until this
condition is fixed, or the affected subdisk is dissociated.
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late to prevent the plex from becoming out-of-date with respect to the volume.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:
