To prevent a Hyper-V host server from automatically assigning drive letters to newly mapped volumes, disable the automount feature. Automount is enabled by default. Disabling automount is beneficial in recovery scenarios when having the host automatically assign drive letters to previously formatted volumes is undesirable. These volumes could include a thin clone of an existing volume. Disabling automount can also be helpful when it interferes with a recovery process. We recommend disabling automount on Hyper-V servers in a PowerStore environment.
The following figure shows how to disable the automount feature by running diskpart from a command prompt with administrator privileges.
