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
