metrocluster configuration-settings calibration measure

Measure latency and bandwith values

Availability: This command is available to cluster administrators at the advanced privilege level.

Description

The metrocluster configuration-settings calibration measure command measures the bandwidth and latency between local and remote nodes in a MetroCluster over IP configuration.

This command should not be run when the MetroCluster configuration is under a heavy load. Bandwidth measurements will attempt to fully saturate network connections to the remote cluster and may disrupt the quality of service.

Examples

The following example shows the output for the calibration measure command in MetroCluster over IP configurations:

	clusA::*> metrocluster configuration-settings calibration measure

	Warning: This operation will attempt to fully saturate the network connection to
		 the remote cluster for measuring bandwidth. This may disrupt
	         performance and should not be run when MetroCluster is under heavy
		 load. Do you want to continue? {y|n}: y
