TEMPRM Plex State

A TEMPRM plex state is similar to a TEMP state except that at the

completion of the operation, the TEMPRM plex is removed. Some

subdisk operations require a temporary plex. Associating a subdisk with

a plex, for example, requires updating the subdisk with the volume

contents before actually associating the subdisk. This update requires

associating the subdisk with a temporary plex, marked TEMPRM, until

the operation completes and removes the TEMPRM plex.

If the system fails for any reason, the TEMPRM state indicates that the

operation did not complete successfully. A later operation dissociates and

removes TEMPRM plexes.

TEMPRMSD Plex State

The TEMPRMSD plex state is used by vxassist when attaching new data

plexes to a volume. If the synchronization operation does not complete,

the plex and its subdisks are removed.

Plex Condition Flags

vxprint may also display one of the following condition ﬂags in the

STATE ﬁeld:

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normal volume I/O. The plex is out-of-date with respect to the volume,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 could 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 the 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.
