Function: Concisely summarizes how each DASD volume group is
allocated. This summarization can be 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 first node
of the data set name into an owner description.
Features: For SMS users, grouping for this report is
automatically done based on the storage group
assigned to each volume.
For non-SMS users, grouping is done by means of a
volume table that is created by the StorageMate
product and maintained by you.
Even after volume pooling is implemented, both SMS
and non-SMS users can use this volume table to
simulate proposed changes before they are made.
All current VCA files are combined for this
report. 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 within the
group. The ability to select the summarization
element allows users to have many different views
of the same data.
The report lists all users who have data sets
allocated on each volume group, with the users
occupying the most space listed first.
The report also detects potential allocation
problems at the volume group level and identifies
users that are allocating data sets on the wrong
groups.
Both color graphic and printer plots are
supported.
Generation of the summary report is automatic.

Issues: Prior to SMS implementation, this chart can be
used to simulate storage groups, making sure that
volumes with similar allocation patterns are
grouped together.
After implementation, the same chart can be used
to monitor and tune each group, and to simulate
proposed changes to the groups.
COLUMN DESCRIPTIONS
Volume Group Name
The volume group to which the information that
follows will apply. Volume group is determined
automatically for SMS users, as it is the same as
the SMS storage group. For non-SMS users, volumes
can be assigned to volume pools (at least for
reporting purposes) by specifying a Volume Group
Table name on the report options screen.
User
The identification of this user of the volume
group. 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
<====' under this column is used to represent
unallocated space in the volume group.
Percent of all Space
The percentage of this volume group that is
allocated to data sets belonging to this user.
For the Free Space entry, this represents the
percentage of the volume group that is unused.
Entries under this column are sorted so that the
primary users of the volume group appear first.
Total Space (MB)
The total amount of space, expressed in millions
of bytes (megabytes) allocated from this volume
group on behalf of this user. For the Free Space
entry, this represents the amount of space in the
volume group that is unused. Entries under this
column are sorted so that the primary users of the
volume group appear first.
Percent of all Data Sets
The percentage of all the data sets allocated on
this volume group that belong to this user. This
will contain a value of zeros for the Free Space
entry.
Total Number of Data Sets
The number of data sets allocated on this volume
group that belong to this user. This will contain
a value of zeros for the Free Space entry.
Minimum Size (KB) Data Set
The smallest data set allocated on this volume
group that belongs to this user, expressed in
thousands of bytes (kilobytes). This will contain
a value of zeros for the Free Space entry. This
will also contain zeros for users that have data
sets with VTOC entries but no tracks allocated.
Maximum Size (KB) Data Set
The largest data set allocated on this volume
group that belongs to this user, expressed in
thousands of bytes (kilobytes). This will contain
a value of zeros for the Free Space entry.
