Poor ventilation and cooling in and around the machine that hosts your administration server and a clustered managed server causes a local hard drive failure and thus both servers crash as well. This is the first time this crash has occurred in production but an automatic Whole Server Migration kicks in as expected. The clustered server migrates to a machine on which it has never run before, and for that reason the server cannot be started on this new machine. Which action could have helped to launch this migrated clustered server? (Choose the best answer.) 

Answer options:

A. Shut down and relaunch the Node Manager.
B. Ensure that the Administration Server is up when the server migration is being performed.
C. First restart the Administration Server, remove this managed server from the cluster, restart it manually, and then target it back to the cluster.
D. Use a shared disk/NFS for all the migratable servers in the cluster.
E. Copy the Node Manager security files to the new machine that hosts your migrated server.

D

There is no built-in mechanism for transferring files that a server depends on between machines. Using a disk that is accessible from all machines is the preferred way to ensure file availability. If you cannot share disks between servers, you must ensure that the contents of domain_dir/bin are copied to each machine.
