CDP-protected VM gets turned off
With heavy load of database transactions, CDP protected VMs on ESXi hosts might get turned off. This situation occurs mostly when the VM performs database schema drop or recreate operations. The subsequent backup jobs for this VM fail with the error The VM to be backed up is disconnected from CDP gateway.
Workaround:
A VM crash does not create data loss. Keep sufficient CPU and memory free to handle sudden IO burst on ESXi. When the VM is back online, NetBackup CDP catches up with the pending I/Os. For HA VM, the VM restarts automatically.
