CentricStor - Virtual Tape Library
Operation
2.4 Operation
CentricStor is operated via the graphical user interfaces GXCC (Global Extended Control
Center) and XTCC (Extended Tape Control Center). These are used to perform all
administration and configuration tasks.
Using this control center, it is possible to display the current operating statuses of all
CentricStor components, together with a large amount of performance and utilization data.
For a description, refer to
chapter “Operating and monitoring CentricStor” on
page 83
,
chapter “GXCC” on page 119
and
chapter “XTCC” on page 325
.
2.5 Administering the tape cartridges
Tape cartridge administration is performed separately by the PLM for each physical volume
group (PVG) (see also
section “Partitioning on the basis of volume groups” on page 63
).
Each PVG has its own scratch pool. All reorganization parameters can be set separately for
each PVG.
2.5.1
Writing the tape cartridges according to the stacked volume principle
The figure below shows the location of logical volumes on the magnetic tape:
Figure 9: Position of the logical volumes on the magnetic tape
Each tape cartridge of the robot archive is administered by CentricStor as a stacked
volume, where a series of logical volumes is stored consecutively on the tape. In this way,
tapes are filled almost to capacity. There will be a small section of unused tape, since a
logical volume will always be written in full onto a physical tape cartridge (no continuation
tape processing).
