Function: Concisely summarizes how each DASD volume is
allocated. This summarization is done using one
or more of the account fields, one node or more of
the data set name, or using a user-defined table
that translates the data set name prefix into an
owner description.
Users planning for products that support volume
pooling can use this report to detect allocation
patterns useful in defining volume groups.
Features: 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.
Information relating to HSM storage may also be
included. The ability to select the summarization
element allows users to have 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.
Lists all groups who have data sets allocated on
each volume, with the groups occupying the most
space listed first.
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.
HSM storage data will be shown will the logical
values of 'HSMLV1' (migration level 1), 'HSMLV2'
(migration level 2) or 'HSMBAC' (HSM backup
storage).
User
The identification of this 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 <====' under this
column is used to represent unallocated space on
the volume. Free space will not be shown for HSM
data.
Total # of Data Sets Present
The number of data sets allocated on this volume
that belong to this user. This will contain a
value of zeros for the Free Space entry.
Percent of all Data Sets
The percentage of all the data sets allocated on
this volume that belong to this user. This will
contain a value of zeros for the Free Space entry.
Space Allocated in MB
The total amount of space, expressed in millions
of bytes (megabytes) allocated from this volume on
behalf of this user. For the Free Space entry,
this represents the amount of space on the volume
that is unused. Entries under this column are
sorted so that the primary users of the volume
appear first.
Percent of all Space
The percentage of this volume that is allocated to
data sets belonging to this user. For the Free
Space entry, this represents the percentage of the
volume that is unused. Entries under this column
are sorted so that the primary users of the volume
appear first.
Minimum Size (KB) Data Set
The smallest data set allocated on this volume
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 that
belongs to this user, expressed in thousands of
bytes (kilobytes). This will contain a value of
zeros for the Free Space entry.
