When many virtual machines perform boot operations at the same time, you might see errors during array-based and vSphere Replication recovery.
Problem
When powering on many virtual machines simultaneously on the recovery site, you might see these errors in the recovery history reports:
- The command 'echo "Starting IP customization on Windows ..." > > % VMware_GuestOp_OutputFile%.
- Cannot complete customization, possibly due to a scripting runtime error or invalid script parameters.
- An error occurred when uploading files to the guest VM.
- Timed out waiting for VMware Tools after 600 seconds.
Cause
By default, Site Recovery Manager does not limit the number of power-on operations that can be performed simultaneously. If you encounter errors while virtual machines power on on the recovery site, you can modify the vmware-dr.xml file to set a limit on the number of virtual machines that power on simultaneously.
If you encounter these errors, limit the number of power-on operations on the recovery site according to the capacity of your environment for a standalone host or for a cluster.
