If the servers are offline then it won't be consider for load balancing.
Note:These are my personal opinions, nothing to do with my employer

Several weeks ago we replaced the three servers with a similarly configured cluster upgraded to the current patch level. The data store was migrated from the original cluster to the new cluster. The group has now been running some time and we are seeing the majority of sessions (active and pseudo) landing on one of the servers (master). The ratio of sessions is approximately (100:2:20). In fact the middle server now has no sessions (after a restart). This is quite different from the behaviour we have seen previously where the sessions balance reasonably well. Nothing obvious in the SunRay or systems logs. Would anybody be able to suggest a possible cause and consequent solution?
