VM,s Failed while Draining the Roles

Hi Team,

We have 10 Node clustering Environment. In that when i drain the role from one node  for patching maintenance. while Draining the role few of the VM's like 10 to 15 VM's  getting  failed status in the Roles section from different nodes.

I tried bring Power ON those VMs from Hyper-V but it's failed.

And Entire cluster is getting refreshing every 5 Mints.

But our Onsite folks solved the problem after 10 Mints when he come to know while i am asking he is not sharing the information to me. 

I know it should be the know issue i researching many website but i am still curious how will be solved by 10 Mints.

Cluster Event IDs:

1205,1254,1069,21502

Thanks and Regards
