Existing MEDMs continued to be connected to h1iscex, but no new connections were possible. Also I was unable to ping or ssh to h1iscex on the FE-LAN. This also meant that the Dolphin manager was unable to put this node into an offline state. The only recourse was to put SUS-EX and SEI-EX into a safe state and remotely power cycle h1iscex via its IPMI management port. As expected, this in turn glitched the attached Dolphin nodes in the EX-Fabric (h1susex and h1seiex). I restarted all the models on these two systems and Ed is now recovering EX.
