CUTDEVRTM

Syntax

Syntax explanations

The number is a value that indicates the I/O response time, in milliseconds.

Rules

• The CUTDEVRTM command works together with the CUTDEVIOR and the CUTDEVUTL commands.

  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 for CUTDEVRTM is 50 milliseconds per I/O response time.

  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

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.
