Before initiating vCHA, perform the below steps on the vCSA active node -

• Take a snapshot of the vCSA VM.
• Login to vCSA with root credentials via SSH.
• Modify statsmonitor service config for vMon

               sed -i '/StartTimeout/d' /etc/vmware/vmware-vmon/svcCfgfiles/statsmonitor.json

               sed -i '/ApiHealthFile/a "StartTimeout": 600,' /etc/vmware/vmware-vmon/svcCfgfiles/statsmonitor.json

• Reload vMon service config through SIGHUP

               kill -HUP $(cat /var/run/vmon.pid)

• Stop and start statsmonitor service.

               /usr/lib/vmware-vmon/vmon-cli -k statsmonitor

               /usr/lib/vmware-vmon/vmon-cli -i statsmonitor

• Enable vCHA.
