Function: This facility allows the storage administrator to
monitor the allocation of space across both the
real DASD and HSM platforms. In a typical HSM
environment, as data becomes less frequently used
it should migrate off of primary, or Level 0,
storage and onto HSM migration level 1 storage.
If the data continues to remain inactive, it
should eventually migrate onto HSM level 2
storage. The HSM backup facility might also be
employed to make regular incremental backups of
data sets. The reports produced by this facility
will give the storage administrator a concise
summary of how the data sets in a particular group
are allocated across these various storage levels.
These reports may be useful when investigating
short-term capacity or performance problems. They
can also detect problems caused by an HSM or SMS
parameter not being set correctly, as well as
problems caused by users not following
installation standards.
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 its system (SYSID).
These various levels of summarization make it easy
to isolate particular problems or trends. For
example, if you summarize by SYSID on a regular
basis, you will get a general feeling of the
health of your storage system. When you discover
an anomaly in one of these summaries, additional
reports at different summarization levels can
isolate the problem to a particular group, or even
a particular SMS class.
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 charts, or color graphic charts.
Summarization by both SMS storage class and
management class may be done in the same report
execution.
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, can verify that
changes made to the HSM parameters in a management
class are working as intended.
ELEMENT 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 sub-grouping by storage class was requested,
this indicates the name of the SMS storage class
represented by this chart. All of the data sets
used to create this particular chart were assigned
to the indicated storage class.
Management Class
If sub-grouping by management class was requested,
this indicates the name of the SMS management
class represented by this chart. All of the data
sets used to create this particular chart were
assigned to the indicated management class.
PRIMARY (L0)
A pie slice with this label represents the amount
of space allocated by data sets in this summary
group on primary (level 0) storage. Numeric
values may be present indicating the total amount
of space allocated, expressed in megabytes
(millions of bytes), and also the percentage of
all space for this user represented by this pie
slice.
MIGRATE LEVEL 1
A pie slice with this label represents the amount
of space allocated by data sets in this summary
group on HSM migration level 1 storage. Numeric
values may be present indicating the total amount
of space allocated, expressed in megabytes
(millions of bytes), and also the percentage of
all space for this user represented by this pie
slice.
MIGRATE LEVEL 2
A pie slice with this label represents the amount
of space allocated by data sets in this summary
group on HSM migration level 2 storage. Numeric
values may be present indicating the total amount
of space allocated, expressed in megabytes
(millions of bytes), and also the percentage of
all space for this user represented by this pie
slice.
BACKUP
A pie slice with this label represents the amount
of space allocated by data sets in this summary
group on HSM backup storage. Numeric values may
be present indicating the total amount of space
allocated, expressed in megabytes (millions of
bytes), and also the percentage of all space for
this user represented by this pie slice.
