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, 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.
DFSMS Storage Class
If sub-grouping by storage class was requested,
this indicates the name of the SMS storage class
represented by this summary line.
DFSMS Management Class
If sub-grouping by management class was requested,
this indicates the name of the SMS management
class represented by this summary line.
*TOTAL* Data Sets
Represents the total number of data sets in this
summary group allocated across all storage
platforms. This includes online DASD (primary or
level 0), HSM migration levels 1 and 2, and HSM
backup. Note the data set count for HSM backup
data sets does not include multiple backup copies
of the same data set.
*TOTAL* Megabytes
Represents the total amount of space allocated, in
megabytes, by all the data sets in this summary
group allocated across all storage platforms.
This includes online DASD (primary or level 0),
HSM migration levels 1 and 2, and HSM backup.
Note the space allocated for HSM backup data sets
includes space allocated by multiple backup copies
of the same data set.
Data Sets on Levl 0 Storage
Represents the total number of data sets in this
summary group that reside on primary (or level 0)
volumes.
Megabytes on Levl 0 Storage
Represents the total amount of space allocated, in
megabytes, by all the data sets in this summary
group that reside on primary (or level 0) volumes.
Data Sets on Levl 1 Storage
Represents the total number of data sets in this
summary group that reside on HSM migration level 1
storage.
Megabytes on Levl 1 Storage
Represents the total amount of space allocated, in
megabytes, by all the data sets in this summary
group that reside on HSM migration level 1
storage.
Data Sets on Levl 2 Storage
Represents the total number of data sets in this
summary group that reside on HSM migration level 2
storage.
Megabytes on Levl 2 Storage
Represents the total amount of space allocated, in
megabytes, by all the data sets in this summary
group that reside on HSM migration level 2
storage.
Data Sets on Backup Storage
Represents the total number of data sets in this
summary group that reside on HSM backup storage.
If a data set has multiple backup copies, it is
still only counted once in this total.
Megabytes on Backup Storage
Represents the total amount of space allocated, in
megabytes, by all the data sets in this summary
group that reside on HSM backup storage. This
amount includes space occupied by multiple copies
of the same data set.
