"Reconnect host" task appears multiple times during ESXi host reboot in Deep Security Manager

Summary

During the preparation of ESXi host upgrade, Deep Security Manager (DSM) generates a lot of "Reconnect host" tasks in vCenter event log.

Details

The issue happens because rebooting the cluster node may take a long time, causing "Reconnect host" event to spam the vCenter console.

To prevent the said message:

Before starting the Prepare host command, manually set the ESXi host to Maintenance Mode.
Select No when asked to automatically reboot the host.
After the preparation, manually reboot the host.
Manually exit the Maintenance Mode when needed.
