Source: VCAVOA file at the DETAIL timespan
HARDVA file at the DAYS timespan
Function: A detailed listing of all volumes that are
considered "exceptional" during the clustering
process.
This permits a rapid review of those volumes that
represent potential performance problems, so that
they can be subjected to further analysis.
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.

COLUMN DESCRIPTIONS
Cluster
The identification of the reporting cluster; an
integer from one to n.
Logical Control Unit (ID)
A four byte field assigned by the z/OS IOCP
process that identifies the specific logical
control unit (LCU) where each volume resides. The
LCU is a logical representation of one or more
physical control units and their associated I/O
devices and is used to control (queue) all I/O
operations.
Control Unit Address
A three-byte field that gives the logical address
of an I/O control unit.
Device Number
The physical address of an I/O device.
Volume (Serial Number)
The volume serial number of the storage medium.
Device I/O Rate
The average (mean) number of I/O operations, per
second for the reported volume.
Average Response Time
The average (mean) response time for the reported
volume. This is calculated as the sum of device
connect, disconnect and pending (busy) times,
divided by the total number of I/O operations
(SSCH Count). The result is then added to the
average queue time.
