Tape library information (external)
Function: This facility allows the storage administrator to
monitor the day-to-day allocation of new data
sets. This permits early identification of groups
or users that are allocating excessive space or
using space incorrectly. One of the most common
causes of space shortages in a typical
installation is the intentional or unintentional
allocation of large new data sets. These reports
will help solve that type of problem, as new data
sets occupying large amounts of space can be
easily identified and corrected before they cause
space shortages.
The facility permits you to indicate which data
sets are to be considered new for the purposes of
the reports. This option can help provide many
different views of the same data. For example,
you could analyze all the data sets created
yesterday to isolate problem data sets, or you
could look at all data sets created in the last
month to establish growth patterns for each
department.
Because this facility also supports input data
describing the tapes in your tape library, the
reports can also prove useful to those measuring
the usage and growth of that resource. Those
persons responsible for tuning DFHSM or DFSMS can
also benefit from running these reports with HSM
input to determine how soon new data sets are
migrated to HSM.
Features: Summary reports can show new allocation trends
based on volume serial number, volume group (or
SMS storage group), system, SMS management class,
SMS management class, one or more data set name
nodes, one or more CA MICS accounting fields, or
by using an external table of data set name
patterns. Each summary report can be produced as
a tabular report, printer graphic report, or color
graphic report. Up to two different summary
elements may be specified, to provide you with
many different data views.
If a summary report indicates a potential problem
or anomaly, a detailed report can be produced to
give more information about individual new data
sets. You can specify whether all new data sets
should be listed or just the largest. You can
also specify whether the sort order of the detail
report should be based on data set name or size.
Data filtering allows you to include data from
selected groups. For example, you can choose to
report on specific volumes, volume groups, or
select new data sets allocated by only certain
users or departments.
SMS
Issues: The reports in this facility will help you
maximize your storage usage while SMS
implementation is taking place. Even after SMS is
fully implemented, poor allocation practices will
still occur, as users can still override many of
the SMS defaults. The ability to monitor new data
set activity by storage group, storage class or
management class will also help you make sure your
SMS system is working as designed.
COLUMN DESCRIPTIONS
SYSID
This value appears at the top of each page and
identifies the System Identifier (system) to which
this data applies.
Data Set Name
Indicates the name of the new data set. All of
the data sets that appear on this detailed report
are considered "new" as determined by the options
you coded on the report options panel.
Alloc Space (MB)
The amount of storage space being allocated by
this data set, expressed in megabytes.
Used Space (MB)
The amount of storage space allocated by this data
set that is actually being used for the storage of
data. The value is expressed in megabytes.
Volume Serial Number
The serial number of the volume on which this data
set resides.
Date Created
The date this data set was created, in the format
ddmmmyy.
Date Last Used
The date this data set was last referenced, in the
format ddmmmyy.
Data Set Org.
The data set organization for this data set.
Block Size
The block size (BLKSIZE) of this data set.
Record Length
The logical record length (LRECL) of this data
set.
Record Format
The record format (RECFM) of this data set.
