Error: “No servers available for disk” When Booting from vDisk

When configuring a vDisk for private mode, any device booting from that vDisk gets the “No servers available for disk” error.

For example, when connecting to the Provisioning Services (PVS) console on the first server, the vDisk is listed as private mode. When the console is connected to PVS console on the second server, the error appears when viewing the vDisk.
