Function: Visually summarizes how each DASD volume is
allocated. Chart summarization is done using one
or more of the account fields, one or more nodes
of the data set name, or using a user-defined
table that translates the data set name prefix
into an owner description. The chart makes it
easy to quickly identify the major users of each
volume.
Users planning for storage products that support
volume pooling can use this report to detect
allocation patterns useful when defining volume
groups.
Features: All current VCA files are combined for this chart.
The VCADAA file provides non-VSAM data set
information, the VCA_VS file provides VSAM data
set information, and the VCAVOA file provides free
space information for each volume. Allocation
information from HSM storage may also be included.
The ability to select the summarization element
allows users to have many different views of the
same data.
Detects potential allocation problems at the
volume level, and identifies groups that are
allocating data sets on the wrong volumes.
Both color graphics and printer charts are
supported.
SMS
Issues: Identifying the primary users of volume space is
an important step when planning SMS storage
groups. This report will enable you to group
volumes with similar allocation patterns together,
thus avoiding potential performance and capacity
problems caused by conflicting users.
COLUMN DESCRIPTIONS
Volume Serial
The volume serial number of the storage medium.
Data on HSM storage will be shown will the logical
values of 'HSMLV1' (migration level 1), 'HSMLV2'
(migration level 2) or 'HSMBAC' (HSM backup
storage).
Pie Slices
The pie slices represent the total amount of space
on the volume allocated to each user, expressed in
millions of bytes (megabytes), and also as a
percentage of the total.
Pie Labels
The labels on each slice identify the user of the
volume. Based on values coded on the report
options panel, this identification can be built
using one or more nodes of the data set name, one
or more of the VCA account fields, or using an
external Data Set Name Table to associate a data
set with its owner. A value of '====> FREE SPACE
' is used to represent the portion of the volume
that is not assigned to any user, and is available
for new allocations. Free space will not be shown
for HSM storage.
