VM fails to boot after ASR failover

Hi,

After a test failover the VM (WS 2012 R2 core) has problems booting. It starts chkdsk on boot for C:, then goes into "preparing devices" and it does not always boot successfully at all.

The source VM seems to be OK - no chkdsk problems, no problems rebooting, no eventlog errors etc.

Other VMs have no such problems.

I have tried reprotecting (establishing replication from scratch), to no avail.

Kind regards,

Pawel

    i can add some potential analysis methods

    • Verify the failed VM network configuration
    • Use a tool like bcdedit to export the Boot Configuration Data for comparison.
    • Run chkdsk /f /r for more thorough repair.
