Initial CMC Config File

The cmc config file is /etc/gridservices/cmc.yaml. The Orbit administrator creates this file. Once created, only the 'node_alias' and the 'inactive_list' fields are dynamically updated by the CMC. At creation, the administrator can set a list of nodes to INACTIVE by specifying the node coordinates in the 'inactive_list' of the testbed.

Config File Updates

On startup, CMC will dynamically update the 'node_alias' field of this config file based on the existing interfaces specified in the inventory database. If there are no nodes for an interface, then "NONE" is specified for that interface.

node_alias:
    - "Atheros 802.11a/b/g:  [[13,14], [20,20], [1,17], [17,11], [11,6]]"
    - "Intel 802.11a/b/g: NONE"
    - "Belkin Bluetooth USB: NONE"
    - "Crossbow Telos Rev.B MOTE: NONE"
    - "GNURadio USRP: NONE"
    - "Marvell 88E8001 Gigabit Ethernet Controller: NONE"
    - "Intel Corporation 82540EM Gigabit Ethernet Controller: NONE"
    - "Intel 802.11a/b/g:  [[11,1], [20,4], [15,15], [20,18], [20,8]]"

The 'inactive_list' field will be dynamically updated for whenever the user sets a node to ACTIVE/INACTIVE. When a node (that is currently ACTIVE) is set to INACTIVE, the node coordinates are added to this field. Again when a node that is currently INACTIVE is set to ACTIVE, the coordinates for that node are removed from the 'inactive_list'.

Example

A) inactive_list: "[]"

B) wget -O - "http://cmc:5012/cmc/nodeSetNodeInactive?domain=grid.orbit-lab.org&nodes=[1,1..2]"
   inactive_list: "[[1,1], [1,2]]"

C) wget -O - "http://cmc:5012/cmc/nodeSetNodeActive?domain=grid.orbit-lab.org&nodes=[1,1..2]"
   inactive_list: "[]"
