Function: Provides a summary of the allocated space within
each DFSMS Storage Group within each primary
summarization group. The total number of data
sets and allocated space for each summarization
group is presented, and the amount of space
distributed within each Storage Group is also
displayed. You can quickly determine the overall
"health" of the storage subsystem, by reviewing
the mapping of allocations for each summarization
group across the respective Storage Groups. The
default value for the primary summarization group
is Storage Class. Generally, each Storage Class
should map to only a small number of groups,
ideally one to one. When a given storage class
maps to many groups, the definitions within the
Storage Class should be reviewed and adjusted as
required.
The report format is controlled by limiting the
number of Storage Groups to be displayed in the
report. This filtering is done by selecting those
storage groups that represent at least 2 percent
of all data sets and combining all others into a
single definition. Additionally, all non-SMS
managed data sets are grouped together as well.
Features: An additional element for summarizing and
reporting the allocation data can be specified.
For example, the DFSMS Management Class can be
specified so that all allocations are mapped by
management class within storage class to better
verify the DFSMS definitions.
SMS After SMS implementation, the report is useful as
Issues: part of the ongoing monitoring and tuning of the
SMS system.
COLUMN DESCRIPTIONS
The valid data element choices for primary summarization
key are: STORAGE (storage class); MANAGE (management
class); DATA (data class); and ACCOUNT, one of the
VCAACTx elements. The default value is STORAGE.
An additional element can be used for secondary
summarization. The valid choices are: MANAGE
(management class); DATA (data class); ACCOUNT (VCAACTx);
and NONE. The default value is NONE, indicating that
only primary summarization will be used.
Following is a list of field descriptions for the
summarization elements.
Storage Class
The name of the DFSMS Storage Class assigned to
this data set. A value of '(NONE)' indicates that
no value has been assigned.
Management Class
The name of the DFSMS Management Class assigned to
this data set. A value of '(NONE)' indicates that
no value has been assigned.
Data Class
The name of the DFSMS Data Class assigned to this
data set. A value of '(NONE)' indicates that no
value has been assigned.
Account fields
These are the VCAACTx elements that were specified
during VCA component installation. Any of the
defined account codes may be chosen; however, the
report design limits the display of any
summarization elements to 12 bytes.
The DFSMS Storage Group, discussed below is not used for
summarization purposes, but is used to display the
distribution of allocated space.
Storage Group
The name of the DFSMS Storage Group assigned by
the installation. Only those Storage Groups that
represent at least 2 percent of the allocated
space are selected and then only the top 8 groups
are actually displayed. All others are grouped
together as "OTHER".
Number of Datasets
The number of data sets within the summarization
group.
Total Space (MB)
The total allocated space, displayed in megabytes
within the summarization group.
