When attempting to failover/failback a VM, it may fail at Step 5 (failback) or Step 2&4 (failover). It may be confirmed the same VM(s) were able to failover/failback previously and no changes have been made in the environment.
VMware Live Cyber Recovery 7.26.x and older
A failover/failback may fail if the same set of VMs has been failed over/back more than 8 times. This limitation is due to a clone depth limit, and it cannot be reduced/increased in the current version.
The limitation is removed in VMware Live Cyber Recovery version 7.27.x and later.
Workaround:
To workaround the issue in the current version, please clone the VM and perform the failover/failback on the cloned VM.
