We are having an issue with one of the HBA's on a host within a 4-node cluster. Each host is currently using an average of 82.75% memory utilization. If I were to put the suspect host into maintenance mode for a reboot, I calculate the memory utilization to increase to 110% per host. This being the case, will I still be able to put a host into maintenance mode? Will the only consequences of doing this be poor performance due to memory swapping? Thank you in advance for your replies.
