Zerto Hyper-V to VMware BSOD

27th March 2017

When converting from Hyper-V to VMware with Zerto you may get a BSOD on boot.

This is due to:

  1. The virtual machine is not configured to start the proper drivers at initial boot time. The 7B error code indicates an inability to locate the disks
  2. Due to Microsoft default SAN policy, the volumes for the virtual machine in the VPG might become offline upon recovery.

To fix, run the following from within the VM or as a script as part of your VPG settings:

san policy=OnlineAll
select disk 1
attributes disk clear readonly
online disk
