Function: Summarizes the installation's usage of various
DFSMS classes.
Helps the user track growth rates of SMS classes,
detect potential problems, and ensure that DFSMS
is assigning classes correctly.
DFSMS classes are set either by the user or by the
DFSMS ACS routines, and are used to group data
sets with similar attributes and needs.
Features: The user specifies the type of class to be
summarized: (data class, storage class, storage
group, or management class). The report shows the
names of the various classes found, the number of
data sets using each class, and the amount of
space this represents, both in terms of space
allocated and space used. Flexible filtering
criteria, plus summarization at both the class and
system levels, allows many different views of SMS
class usage information.
The ability to include data from real DASD plus
HSM allows the ability to monitor SMS classes as
data sets migrate through various storage levels.
SMS This report is useful during SMS implementation to
Issues: ensure that your SMS ACS routines are assigning
class names as designed. After SMS
implementation, the report is useful for
monitoring the usage of SMS classes in various
environments.
COLUMN DESCRIPTIONS
Storage Class
The name of the DFSMS Storage Class for which this
summarization applies. A value of '(NONE)' is
used to represent data sets that have not been
assigned to any class. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report.
Management Class
The name of the DFSMS Management Class for which
this summarization applies. A value of '(NONE)'
is used to represent data sets that have not been
assigned to any class. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report.
Data Class
The name of the DFSMS Data Class for which this
summarization applies. A value of '(NONE)' is
used to represent data sets that have not been
assigned to any class. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report.
Storage Group
The name of the DFSMS Storage Group for which this
summarization applies. A value of '(NONE)' is
used to represent data sets that have not been
assigned to any group. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report. Because Storage Group is not
available for data sets managed by HSM, values of
'HSM LV1' (migration level 1), 'HSM LV2'
(migration level 2) and 'HSM BACK' (HSM backup)
will appear in this column for HSM data.
Total Data Sets
The total number of data sets found in the input
data that were assigned to this class or group.
Non-VSAM Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
were defined as having a data set organization
other than VSAM. This value includes only data
sets that still reside on primary DASD (no HSM
data).
VSAM Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
were defined as having a VSAM organization. This
value includes only data sets that still reside on
primary DASD (no HSM data).
HMIG Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
had been migrated to HSM level 1 or level 2
volumes.
HBAC Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
belonged to data sets residing on the HSM backup
volumes. Each unique data set is only included
once in this count, even if multiple backup copies
exist.
Total Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group, expressed in millions of bytes (megabytes).
Non-VSAM Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and belonged to data sets with a data set
organization other than VSAM. This value only
includes space allocated by data sets still
residing on primary DASD (no HSM data).
VSAM Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and belonged to data sets with a VSAM data
set organization. This value is expressed in
millions of bytes (megabytes), and only represents
data sets residing on primary DASD (no HSM data).
H-Migrate Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and was allocated by data sets that had been
migrated to HSM level 1 or level 2 volumes.
H-Backup Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and was allocated to HSM backup storage.
This value may include multiple backups of the
same data set.
