ESXi remount VMFS

Overview

The ESXi product has a bug that when the cluster is restarted, the cluster is not yet in a healthy state, during which the ESXi side scans early and hangs on VMFS, but it no longer fills up after a certain number of durations; and after the cluster is restored to health, ESXi does not initiate scanning actions anymore.

Write a script, put it on the ESXi side, set a timed task, and initiate a scan.
