Let’s see one of the new functions of vSphere 7u2 and precisely the possibility of parallelizing the remediation function with LifeCycle Manager

We must use the new version of vCenter 7u2 and once we have performed the stage on all the nodes of a cluster we can proceed to remediate by putting first the nodes we want to update in maintenance mode manually

In my case we put three hosts in maintenance mode

Among the additional options, of the remediate phase, we enable parallelism and we can choose whether the number of contemporary hosts on which the update will be made is managed automatically….

… or we manually specify how many to do

And then off….
