Check manual page of 3par_volumes
HPE 3PAR: Volumes
This check measures the utilization of a virtual volume. You
can define thresholds as known by other filesystem checks.
Additionally there is information about the used space of this
virtual volume on the filer, the provisioning type and the
associated WWN. If available there is also information about
the compaction and/or deduplication ratio.
The check will also change the state if the virtual volume on
the filer reports a degraded or failed state.
One service is created for each virtual volume.
