Reorganisation Parameters
PLM Refresh Interval (Days)
Number of days after which this group's volumes are to be refreshed. This value must
be defined in accordance with the tape manufacturer's recommendations.
Value range: min: 90, max: 999, default: 365
Absolute Minimum (Volumes)
Absolute minimum number of free volumes. When this minimum is reached all
resources are used with priority for reorganization. The following hierarchy applies:
Soft Minimum > Hard Minimum > Absolute Minimum.
Hard Minimum (Volumes)
If the number of free volumes specified here is not reached, a reorganization run is
started regardless of the time.
Soft Minimum (Volumes)
If the number of free volumes specified here is not reached, reorganization takes place
in the specified reorganization time.
Fill Grade (%)
During reorganization volumes are recorded in which the share of the capacity
occupied by valid volume images falls below the specified percentage.
Time Frame
Time in which reorganization runs should usually take place. Times with a low
productive load should be chosen here.
Parallel Request Number (Jobs)
When a PV is reorganized, a movement request for each LV of this PV is sent to the
VLM.
The parameter defines the number of such movement requests which can be
processed in parallel. It is the same as the number of parallel movement requests for
the corresponding PV group as at most one PV of a PV group can be reorganized at
the same time.
It must be pointed out that disc space in the TVC will be allocated for this number of LVs.
If the parameter selected is too high, other LVs may be unnecessarily displaced from
the TVC.
Range: min: 2; max: 99; default: 5
Move Cancel Time (sec)
If a move request issued by the PLM to the VLM remains in an unchanged status
beyond this time (in seconds) it is canceled by the PLM. This does not apply for moves
started by an operator command.
Value range: min: 1800, max: 99999, default: 1800
