Tandem Capacity Model (TCM) Manual

NUMCSVS Entry
The NUMCSVS entry specifies the number of CSV files you want MeasTCM to produce. If you do
not specify a value, the default is 1.
The syntax follows:
NUMCSVS * | ALL | n
where:
* | ALL
instructs MeasTCM to produce as many CSVs as possible.
n
is a positive integer.
The number of CSV files generated depends on the start time, stop time, and intervals used in the
input Measure data file or files in addition to the user-supplied CSVLO and CSVHI keyword
parameters. The number of CSV files produced can differ from the requested number.
MeasTCM first calculates the maximum number of CSV files possible based on the lowest common
multiple of the interval times, the start and stop times of the Measure data files, and the user-supplied
CSVLO and CSVHI times if any.
For example, suppose that one Measure data file used has a start time of 10 a.m., a stop time of
11 a.m., and an interval of 5 minutes. With no CSVLO and CSVHI time supplied, the maximum
number of CSVs is 12 (one for every 5-minute interval). If you specify NUMCSVS *, MeasTCM
creates 12 CSVs, each including one interval of 5 minutes.
If you specify NUMCSVS 5, MeasTCM creates 5 CSVs. The first four CSVs include 2 intervals each
(12/5 = 2 intervals, ignoring the remainder), for a total of 10 minutes each. The last CSV includes
4 intervals, for a total of 20 minutes.
Example
This example shows the required entries:

NUMTMFTRAIL Entry
The optional NUMTMFTRAIL entry supports multiple auxiliary TMF audit trails in MeasTCM. If you
do not specify NUMTMFTRAIL in the control file, the default value of one master audit trail is
generated in the CSV file.
The syntax follows:
NUMTMFTRAIL m
where:
m
specifies the number of audit trails used in the measurement. The default value is one master
audit trail (MAT). In addition to the one master audit trail, you can specify up to 15 auxiliary
(AUX) audit trails. Therefore, if you enter 2, one master audit trail and one auxiliary audit trail
is used.
NOTE: NUMTMFTRAIL is a new feature available only from SPR T6042H01^ABC.
DISKCONVERTTO Entry
The DISKCONVERTTO entry represents the output disk model number. If the measurement data
file contains mixed disk types, the CSV file has disk busy seconds scaled to this disk type.
Effective with SPR T6042H01^ABD and later, SAS disks and the write cache enable option are
supported. However, XP disks are partially supported.
