Indicates whether a reorganization
is running for the PV group
If the number of free volumes specified here is not reached, reorganization will take
place in the reorganization time shown further below.
In the event of reorganization between the soft and hard limits, volumes are
recorded whose occupancy level (data volume of the valid cartridge images / data
volume of all cartridge images, specified in %) fall below the value set here.
Time in which the reorganization runs should usually take place. Times with a low
productive load should be chosen here.
Currently only a timeframe common to all weekdays can be selected on the
graphical user interface.
If the number of free volumes specified here is not reached a reorganization run is
started immediately regardless of the occupancy level.
If this number of empty volumes is reached or fallen below, all resources are used
for a reorganization run. Save and restore requests from the VLM which are not
related to the reorganization are not accepted. This considerably restricts the
productive operation of CentricStor.
The following hierarchy applies:
Soft Minimum > Hard Minimum > Absolute Minimum.
