On the VEM, run the vem-health script using the VSM MAC address you found in
Step 3
Note
vem-health check vsm_mac_address
The vem-health script output shows the cause of the connectivity problem and recommends next steps
in troubleshooting.
Example:
~ # vem-health check
VSM Control MAC address: 00:50:56:a3:36:90
Control VLAN: 90
