The problem was if using xCAT to manage the osimage of mic node, the default micuser would be removed. It will be fixed soon.

Stop mpss, run micctrl --initdefaults, then start MPSS.

This means the /bin/coi_daemon on the Phi cards cannot start as the init script runs it with the "--coiuser=micuser" argument so it fails with: [root@barcoo062-mic0 /root]# /etc/init.d/coi start Starting COI server...
