Source: VCAVOA file at the DETAIL timespan
HARDVA file at the DAYS timespan
Function: Concisely summarizes performance and capacity
information at the volume level. This information
is reported for each volume and string.
This makes it easy to identify potential
performance or capacity problems, at both the
volume and string level.
Users planning for storage products that support
volume pooling can use this report to design
various volume groupings to find combinations that
provide optimum performance and availability.
Features: Two different CA MICS files are combined to
produce this report; one provides space
information and the other provides performance
information. The HARDVA file can be filtered at
the hour or zone level so that the performance
information reflects a specific time period.
Volumes that appear in the HARDVA file but not the
VCAVOA file (because they were not scanned) can be
excluded by user option or may still appear on the
report, but will have 'N/A' or zeros in those
fields obtained from the VCAVOA file.
SMS The response time and capacity values obtained
Users: from this report can help when defining SMS
storage classes and storage groups.
COLUMN DESCRIPTIONS
Control Unit Address
A three-byte field that gives the logical address
of an I/O control unit.
Device Address
The physical address of an I/O device.
C.U. Path
The Logical Control Unit (MVS/XA users) or Logical
Channel (non-XA users) through which this volume
is attached to the I/O subsystem.
Volume Serial Number
The volume serial number of the storage medium.
Device Type
The type of I/O device.
Volume Usage
The current DASD Volume Use Attributes. The value
'(N/A)' will appear in this column if this volume
was not found in the VCAVOA file, but was found in
the HARDVA file, and the unmatched volume option
was specified on the report options screen.
SMS Volume Status
The current System Managed Volume Status. The
value '(N/A)' will appear in this column if this
volume was not found in the VCAVOA file, but was
found in the HARDVA file, and the unmatched volume
option was specified on the report options screen.
Volume Free
The percent of space that is available for
allocation on this volume. A value of zero will
appear in this column if this volume was not found
in the VCAVOA file, but was found in the HARDVA
file, and the unmatched volume option was
specified on the report options screen.
Fragmentation Index
A measure of how fragmented the allocated space is
for the current volume. A value of zero will
appear in this column if this volume was not found
in the VCAVOA file, but was found in the HARDVA
file, and the unmatched volume option was
specified on the report options screen.
Total Data Sets
The total number of data sets residing on this
volume. A value of zero will appear in this
column if this volume was not found in the VCAVOA
file, but was found in the HARDVA file, and the
unmatched volume option was specified on the
report options screen.
Non-VSAM Data Sets
The percentage of Non-VSAM data sets residing on
this volume. This is calculated by dividing the
number of Non-VSAM data sets by the total number
of data sets on the volume. A value of zero will
appear in this column if this volume was not found
in the VCAVOA file, but was found in the HARDVA
file, and the unmatched volume option was
specified on the report options screen.
VSAM Data Sets
The percentage of VSAM data sets residing on this
volume. This is calculated by dividing the number
of VSAM data sets by the total number of data sets
on the volume. A value of zero will appear in
this column if this volume was not found in the
VCAVOA file, but was found in the HARDVA file, and
the unmatched volume option was specified on the
report options screen.
Total I/O Rate
The average number of I/O requests per second
being received by this volume.
Average Response Time
The average time a user of this volume waits, in
thousandths of a second (milliseconds), for an I/O
request to complete.
