We have recently integrated Eaton's Intelligent Power Manager (IPM) v1.50 with our VMware hosts. Our configuration doesn't involve vCenter; rather, IPM communicates directly with our 3 x ESXi 5.1 hosts.
The hosts are configured to "Allow virtual machines to start and stop automatically with the system" and the selected Shutdown Action for each host is "Guest Shutdown". All of this works more-or-less as one might expect ... power goes out, 10 mins later VMs start shutting down, then the host shuts down.
Next time VBR backup jobs ran, a CBT-related warning was issued in every job which had a VM which had been shutdown at the last power-out, auto-VM-and-Host-shutdown event: "Cannot use CBT: Soap fault. Error caused by file ... [etc etc]"
My question: is there any easy way to prevent this CBT failure on the next backup run, or will I have to live with it?
I suppose I could manually run some backups right afterwards, thus clearing the CBT issue before the next regularly scheduled backups needed to run, but that's a bit of a clunky workaround. I was hoping there might be a more elegant solution.
