Newly added volumes are not available until they have been initialized by the PLM.
The height of the bar represents the number of volumes. If less volumes are available than
the minimum values usually displayed for “Hard Minimum” and “Soft Minimum”, then the
minimum values cannot be displayed using this form of representation and thus do not
appear on the diagram. This situation occurs regularly when the PVG is being filled.
If CentricStor controls cleaning of the drives in a library, the degree of use of the cleaning
PVG will be shown to the right of the PVG of the library. The representation is, in principle,
identical to that of the PVG. The overall number given under the bar shows the total number
of cleaning cycles that are available. The counter shows how many of these cycles have
already been used. The “Soft Minimum” (green number, green line) specifies how many
cycles must still be available when the soft minimum is achieved. The “Hard Minimum” (red
number, red line) specifies the minimum for the “Hard Minimum”. These values are specified
by CentricStor according to the number of tape drives, and cannot be modified at the user
interface.
If “Hard Minimum” and “Soft Minimum” are violated, a message is output on the operator
console indicating the degree of urgency.
How to use and administer the physical volumes in CentricStor is described in the section
“Administering the tape cartridges” on page 35 .
