Symptoms
PSU or Disk cannot be contacted on physical view of VxRail Manager plug-in, but it is present and working everywhere else.
This issue may happen when performing PSU or Disk replacement or expansion but the action is not triggered from VxRail manager plug-in UI, for example from vCenter procedure directly or by powering off the host then performing physical parts replacement directly.
Cause
When the PSU or Disk serial number or slot number does not match with the baseline file on the host, physical view displays that PSU or Disk "cannot be contacted."
