Excerpt from
Understanding the Special Items in the Job Queue
IMPORTANT: ‘Wait for host to go offline and come back online’ should be used carefully. In particular, we do not recommend using this special action with virtual machine target computers. The reason for this is because virtual machines can often reboot within just a couple of seconds, which unfortunately can be too fast for BatchPatch to successfully detect. If the machine reboots so rapidly that BatchPatch does not know that it ever went offline, then ‘Wait for host to go offline and come back online’ will hang until the global timeout is reached, which will leave you with undesirable results. Here is one possible way you might use ‘Wait for host to go offline and come back online’ in your job queue when the target computer is not a virtual machine.
You could instead do something like this:
Step 1: Download and install updates + reboot always
Step 2: Wait 10 minutes
Step 3: Wait for host to be detected online
Step 4: Download and install updates + reboot if required
