look at the following commands:
rocks set host name rocks set host rank rocks set host rack rocks set host interface name
e.g. to change the name of compute-0-0 to compute-10-13
# rocks set host name compute-0-0 compute-10-13
# rocks set host rank compute-10-13 13
# rocks set host rack compute-10-13 10
# rocks set host interface name compute-10-13 eth0 compute-10-13
# rocks sync config
# rocks sync host network compute-10-13
# rocks run host compute-10-13 "shutdown -r now"
rocks run host "service rocks-grub off"
rocks run host "service rocks-grub stop"
rocks run host "shutdown -r now"
