CUTDEVIOR number

Syntax explanations

The number specifies the minimum I/O rate per second.

Rules

  • The CUTDEVIOR command works together with the CUTDEVRTM and the CUTDEVUTL commands as follows:

    A device is not included in the result files if its activity is below all three limits set by the CUTDEVIOR, CUTDEVRTM, and CUTDEVUTL commands, that is, if it has less than the CUTDEVIOR I/O rate per second and less than the CUTDEVRTM millisecond per I/O response time and less than the CUTDEVUTL percentage device utilization.

  • The default value for CUTDEVIOR is an I/O rate of 10 per second.

    For modeling purposes activity, all of the excluded devices are accumulated in delay server AGGR. For Visualizer activity, all of these devices are included in the total SSCH rate by logical system.

Examples

CUTDEVIOR 15
CUTDEVRTM 10
CUTDEVUTL .01

In this example, devices with utilization >0.1% will never be excluded even if their I/O rate is <15% and response time is <10 msec per I/O.
