  1. Check the serial ID and on which DG the VM is present. In the case of FC-0 (_DCF_default___RR-INE-0_RE0_), this is DG0 and the serial is " 15013 ".

[root@dg0 ~]# ccif_vm_ports
TAG NODE PID SERIAL MONITOR VNC ACTIVE
_TAG_DRE_ dg1 17189 15010 20010 10 1
_TAG_DCF_ROOT_RE1_ dg1 5381 15009 20009 9 1
_TAG_DCF_ROOT_RE0_ dg0 26272 15010 20010 10 1
_DCF_default___NW-INE-0_RE0_ dg1 23583 15007 20007 7 1
_DCF_default___RR-INE-0_RE0_ dg0 20773 15013 20013 13 1
_DCF_default___NW-INE-0_RE1_ dg0 5786 15012 20012 12 1
_DCF_default___RR-INE-1_RE0_ dg1 7786 15013 20013 13 1

  • Telnet to the VM as follows:

[root@dg0 ~]# telnet dg0 15013
