Recovery Initialize 
When a VM recovery is triggered, an escEvent of type VM_RECOVERY_INIT with a status of SUCCESS will 
be sent to Netconf subscribers. This indicates that the recovery workflow has been started. This will 
hard reboot the VM instance and checks if the VM comes back up.  
If the VM comes up successfully, an escEvent of type VM_RECOVERY_COMPLETE with a status of 
SUCCESS with be sent. 
Attempts for recovery 
If the VM did not come up after this attempt, then ESC tries to undeploy and redeploy the VM and 
corresponding  escEvent of type VM_RECOVERY_UNDEPLOYED and VM_RECOVERY_DEPLOYED will be 
sent. If the undeploy and redeploy also fails to get the VM back up, this undeploy and redeploy cycle will 
be retried to a maximum value of “
vm_recovery_retries_max
”
 times which is configurable.
 
Recovery complete 
If the VM comes alive at any attempt during the undeploy and deploy, an escEvent of type 
VM_RECOVERY_COMPLETE with a status of SUCCESS with be sent. But if the VM does not come up after 
all the redeploy attempts, then 
an escEvent of type 
VM_RECOVERY_COMPLETE with a status of FAILURE 
will be sent. 
The various event notifications generated during VM recovery are given below.
