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 may 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, or 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.
Date
Indicates the date for which the statistics on
this line apply. The date is expressed in the
format ddmmmyy.
*TOTAL* Data Sets
The total number of data sets allocated by the
users of this summary group on the indicated date.
This total includes data sets on primary storage,
and DFHSM migration storage.
*TOTAL* Megabytes
The total amount of space allocated, in megabytes,
by the users of this summary group on the
indicated date. This total includes space
allocated on primary storage and DFHSM migration
storage.
Primary (Level 0) Data Sets
The total number of data sets allocated on primary
storage by the users of this summary group on the
indicated date.
HSM ML1 (Level 1) Data Sets
The total number of data sets allocated on DFHSM
migration level 1 storage by the users of this
summary group on the indicated date.
HSM ML2 (Level 2) Data Sets The total number of data sets
allocated on DFHSM migration level 2 storage by
the users of this summary group on the indicated
date.
Primary (Level 0) Megabytes
The total amount of space allocated, in megabytes,
on primary storage by the users of this summary
group on the indicated date.
HSM ML1 (Level 1) Megabytes
The total amount of space allocated, in megabytes,
on DFHSM migration level 1 storage by the users of
this summary group on the indicated date.
HSM ML2 (Level 2) Megabytes
The total amount of space allocated, in megabytes,
on HSM migration level 2 storage by the users of
this summary group on the indicated date.
