Function: This facility allows the storage administrator to
monitor the daily movement of data between real
DASD and HSM migration volumes. Installations
using HSM should experience a daily migration of
less-active data to HSM level 1 and level 2
volumes. If HSM and/or SMS parameters are not set
correctly, or if certain groups or users abuse HSM
commands to cause data set movement, severe
capacity or performance problems may result.
A summary report will analyze the first and last
dates found in the input data, and create a
summary of the changes between those two dates.
This could be used, for example, to analyze data
from a Monday and a Friday and summarize changes
that occurred during the week. If potential
problems are found, history reports can be used to
provide more detailed information about certain
groups or users.
These reports may be useful when changes have been
made to HSM or SMS parameters, to validate the
changes are having their intended effect on the
operation of HSM.
Features: Summarization options allow you to analyze the
data based on its owner (using one or more of the
CA MICS accounting fields), its SMS storage class,
its SMS management class, or by system (SYSID).
These various levels of summarization make it easy
to isolate particular problems or trends.
Data filtering allows you to include data from
selected summary groups. For example, you could
choose to report on specific departments groups or
individuals, or on a specific SMS class.
Output reports from this facility include tabular
reports, printer plots, and color graphic plots.
Reporting can be based on the number of data sets,
the amount of allocated space, or both.
SMS
Issues: The ability to summarize by an SMS storage or
management class makes it easy to monitor the
activity within each of your defined classes. The
ability to filter and summarize by a specific
management class, for example, could be used to
verify that changes made to the HSM parameters in
a management class were working as intended.
COLUMN DESCRIPTIONS
SYSID
This value appears at the top of each page and
identifies the System Identifier (system) to which
this data applies.
Owner
Specifies the department, group, or individual to
which this report applies. This value is
specified as a report option, and represents one
or more of the CA MICS accounting fields assigned
to a group of data sets.
Storage Class
If summarization by storage class was requested,
this indicates the name of the SMS storage class
represented by this report. All of the data sets
assigned to the indicated storage class were
summarized to produce this report.
Management Class
If summarization by management class was
requested, this indicates the name of the SMS
management class represented by this report. All
of the data sets assigned to the indicated
management class were summarized to produce this
report.
If reporting by data set was requested, the following report
columns will be present:
Total Data Sets CHANGE
The difference in the total number of data sets
allocated by this summary group between the two
dates indicated. This value includes data sets
found on primary storage and DFHSM migration
storage. The difference is calculated using the
values for the first and last dates found within
the input data.
Percent Data Sets CHANGE
The percentage change in the total number of data
sets allocated by this summary group between the
two dates indicated. This value includes data
sets found on primary storage, and DFHSM migration
storage. The difference is calculated using the
values for the first and last dates found within
the input data.
Primary Data Sets (date)
This column appears twice--once for the first date
found in the input data, and once for the last
date found. The value in the column represents
the total number of data sets allocated on primary
storage for this summary group on the date
indicated.
Primary Data Sets -CHANGE-
Represents the difference in the number of data
sets reported in the previous two columns. This
represents the difference in the number of data
sets allocated on primary storage between the two
dates shown in previous columns.
HSM Lev1 Data Sets (date)
This column appears twice--once for the first date
found in the input data, and once for the last
date found. The value in the column represents
the total number of data sets allocated on HSM
migration level 1 storage for this summary group
on the date indicated.
HSM Lev1 Data Sets -CHANGE-
Represents the difference in the number of data
sets reported in the previous two columns. This
represents the difference in the number of data
sets allocated on HSM migration level 1 storage
between the two dates shown in previous columns.
HSM Lev2 Data Sets (date)
This column appears twice--once for the first date
found in the input data, and once for the last
date found. The value in the column represents
the total number of data sets allocated on HSM
migration level 2 storage for this summary group
on the date indicated.
HSM Lev2 Data Sets -CHANGE-
Represents the difference in the number of data
sets reported in the previous two columns. This
represents the difference in the number of data
sets allocated on DFHSM migration level 2 storage
between the two dates shown in previous columns.
If reporting by space allocated was requested, the following
report columns will be present:
Total Megabytes CHANGE
The difference in the total amount of space, in
megabytes, allocated by this summary group between
the two dates indicated. This value includes
space allocated on primary storage, and DFHSM
migration storage. The difference is calculated
using the values for the first and last dates
found within the input data.
Percent Megabytes CHANGE
The percentage change in the total amount of space
allocated by this summary group between the two
dates indicated. This value includes space
allocated on primary storage and DFHSM migration
storage. The difference is calculated using the
values for the first and last dates found within
the input data.
Primary Megabytes (date)
This column appears twice--once for the first date
found in the input data, and once for the last
date found. The value in the column represents
the total amount of space, in megabytes, allocated
on primary storage for this summary group on the
date indicated.
Primary Megabytes -CHANGE-
Represents the difference in the amount of space
reported in the previous two columns. This
represents the difference, in megabytes, in the
amount of space allocated on primary storage
between the two dates shown in previous columns.
HSM Lev1 Megabytes (date)
This column appears twice--once for the first date
found in the input data, and once for the last
date found. The value in the column represents
the amount of space, in megabytes, allocated on
DFHSM migration level 1 storage for this summary
group on the date indicated.
HSM Lev1 Megabytes -CHANGE-
Represents the difference, in megabytes, between
the amount of allocated space reported in the
previous two columns. This represents the
difference in the space allocated on HSM migration
level 1 storage between the two dates shown in
previous columns.
HSM Lev2 Megabytes (date)
This column appears twice--once for the first date
found in the input data, and once for the last
date found. The value in the column represents
the amount of space, in megabytes, allocated on
DFHSM migration level 2 storage for this summary
group on the date indicated.
HSM Lev2 Megabytes -CHANGE-
Represents the difference, in megabytes, between
the amount of allocated space reported in the
previous two columns. This represents the
difference in the space allocated on HSM migration
level 2 storage between the two dates shown in
previous columns.
