Enable a SAN Policy for Windows VMs

To enable disks that must be brought online as part of a VM conversion process, enable a SAN policy for the source VM.

Procedure

Open a command line or PowerShell session locally on the VM.
Open the disk partition tool:
```
C:> diskpart
```
Verify that the SAN policy is set to Offline Shared:
```
DISKPART> SAN
SAN Policy : Offline Shared
```
Change the policy to OnlineAll:
```
DISKPART> SAN POLICY=OnlineAll
```
