Switch failure on Nov 17 2018

We will have a reboot of the NetApp as part of an upgrade, starting from 9:30 AM on Monday, November 19, 2018, to address a bug that causes NetApp issues caused by the network switch outage we had on Nov 14, 2018. Any cluster nodes, OnDemand service, and all filesystems won't be impacted by the reboot. We also do not expect any disruptions to users' jobs due to this reboot.
