If there are zero details in any of the CRS related logs about fencing or eviction or anything of that nature, then it sounds like the servers were not evicted by the clusterware. Rather, they hit a hardware/driver fault and restarted. I've seen this happen during storage maintenance work as well. It's tough to ever find a root cause because storage people never want to admit that anything could have gone wrong. If you're using Powerpath or something similar, you may want to check to see if updates are available, or if there are bugs in the release you're using, etc... Good luck.
