History data Global Status
PVG statistics are displayed in the first line.
The next block contains the parameters for controlling reorganization.
soft minimum number of empty PVs:
If the number of free volumes specified here is not reached, reorganization will take
place in the reorganization time shown further below.
amount of valid data for REORG
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.
timeframe for REORG
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.
hard minimum of empty PVs
If the number of free volumes specified here is not reached a reorganization run is
started immediately regardless of the occupancy level.
absolute minimum number of empty PVs
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.
