VxFlex Network Deployment Guide using Dell EMC Networking 25GbE switches and OS10EE

Troubleshoot SDS connectivity

SDS connectivity problems affect VxFlex performance. VxFlex has a built-in tool to verify that all SDS nodes

in a given protection domain have connectivity. From the VxFlex Command Line Interface (SCLI), run the

VxFlex internal network test to verify the network speed between all the SDS nodes in the Protection Domain.

The following commands test all SDS nodes with a payload of 10 GB, using eight parallel threads:

VxFlex-172-16-33-12:~ #

scli --mdm_ip 172.16.33.13 --start_all_sds_network_test

--protection_domain_name PD01 --parallel_messages 8 --network_test_size 10
