17. When asked if you want to start the HP Clustered File System service,
answer yes. If you are not prompted to start the service, go to the
Cluster Wide Configuration tab and start HP Clustered File System on
the upgraded server. The upgraded server will now rejoin the cluster.
18. For each remaining server in the cluster, repeat this procedure
through step 12. Next, open the HP CFS Management Console (if it is
not already open) and import the cluster configuration from a server
running HP Clustered File System 3.6 to the server being upgraded
(the new license is included in the imported configuration). You can
then start the HP Clustered File System service on the newly
upgraded server.
19. After all servers in the cluster are operational, complete the
appropriate post-upgrade steps as described in Chapter 5.
