Unable to cast object of type ‘LogicalUnitPolicy’ to type ‘FixedLogicalUnitPolicy’

When trying to change the Preferred Path on Storage Adapter I was greeted with the following Error message

Unable to cast object of type ‘LogicalUnitPolicy’ to type ‘FixedLogicalUnitPolicy’

I checked my other Storage Adapters and these too gave me the same error.

The Fix

To fix this problem all you need to do is Rescan the Storage Adaptors using the following steps

1. In the vSphere Client, select the Host which has the Storage Adaptors that are giving you the error and click the Configuration tab.
2. In the Hardware panel, select Storage Adapters
3. Select one of your Storage Adaptors and click Rescan above the Storage Adapters panel.
4. Perform Step 3 for the rest of your Storage Adapters.
