2.4.6.4.1 DASD Multiple Volume Analysis Report Inquiry Panel
The DASD Multiple Volume Analysis Report is produced by
executing the DASD Multiple Volume Analysis Report Inquiry
panel (see Figure 2-124). This report normally analyzes and
recommends DASD volumes to be combined together on a higher
density device. You can produce an alternative report that
monitors existing double density volumes (8650s) or proposed
groupings (2, 3, or 4-way) through specifying the MONITOR
option and specifying which volumes are to be grouped.
The following is a discussion of the fields on this panel.
Timespan: The specification of whether the data is to be
taken from the DETAIL or DAYS timespan.
Cycle(s): One or more cycles from the CA MICS files
that you want to use for analysis. Because SMF
data sets are not normally dumped at exactly
midnight at most installations, a cycle from the
CA MICS file usually contains a 24-hour period
spanning two days. Hence, some other type of
selection may be required to generate a daily
report. This selection capability is provided
by the DATE and HOUR control parameters.
Database: The single-character CA MICS identifiers for the
databases you want to access.
Allow The indication of whether the database
Runtime identifier and/or the Cycles specification can
Override: be overridden at inquiry execution time.
Number of The specification that determines whether groups
VOLs to be containing two, three, or four devices must be
combined: combined and reported.
Plot The specification of whether the plot of the
contention inter-volume contention index will be produced
index: for each recommended grouping.
Volume The following three fields combine to specify
Table which volumes are to be analyzed or monitored.
Analysis
Method:
Analyze or ANALYZE specifies that a recommendation report
Monitor: is to be produced. MONITOR specifies that the
groupings you specified will be used in the
analysis.
Analyze Specifies that groups containing unlike device
unlike types (such as a 3380 with a 3350) must be
VOLS: allowed. This is not recommended and will occur
only if explicitly specified.
Specify Specifies that a table of VOLSERs is to be
Volume defined.
Table:
Least The following two fields instruct the inquiry to
Active analyze the specified number of volumes having
Volume the least activity.
Analysis
Method:
Device The device type (3350, 3380) of the DASD that is
type: being combined to a higher density device.
NUM The number of DASD volumes to be analyzed having
of VOLs: the least activity.
Date: The day(s) used for the analysis. This field is
normally used with the IOA Analysis inquiry to
drop the extra day from a cycle due to the
timing of the SMF dump.
Hour: An hour or range of hours for which data is
reported.
Zone: The specification that zone selection is being
applied. If zone 1 definition is 8:00 a.m. to
6:00 p.m., daily reports covering that time
period can be specified by using the ZONE field
set to 1.
Specify The specification that allows you to supply
extended additional report options. These options
options: include special SAS data selection statements,
non-standard input, and output files. These
options are discussed in the sections that
follow.
The operation of the time selection control parameters
depends on definitions made during the installation of
CA MICS. If you are not sure about the zone definitions
for your installation or the CA MICS database update
procedures, consult your CA MICS System Administrator.
