Function: Allows users to obtain a visual summary of 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. The plot makes it easy
to identify the major users of each volume group.
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 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 within the
group. The ability to select the summarization
element allows users to have many different views
of the same data.
This chart 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.
SMS
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 on this
chart will apply. Volume group is determined
automatically for SMS users, because 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.
Pie Slices
The pie slices represent the total amount of space
in the volume pool 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 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
' is used to represent the portion of the volume
pool that is not assigned to any user, and is
available for new allocations.
