During your approved time slot, you will be able to ssh into the console of the respective domain. A console is a dedicated machine that allows access to all resources in that domain.
For example, to access the sandbox1:

- Before we begin using the nodes, it's a good idea to check their status first. This is done with the omf stat command.
omf stat
This omf command is used to display the power status of the node/domain.
Usage: omf stat
username@consoles.outdoor:omf stat Returns the status of the nodes in a testbed Usage: omf-5.4 stat [-h] [-s] [-t TOPOLOGY] [-c AGGREGATE] With: -h, --help print this help message -s, --summary print a summary of the node status for the testbed -c, --config AGGREGATE use testbed AGGREGATE -t, --topology TOPOLOGY a valid topology file or description (defaults to 'system:topo:all') Some Examples: omf-5.4 stat omf-5.4 stat -s omf-5.4 stat -t omf.nicta.node1,omf.nicta.node2 -c sb1 omf-5.4 stat -t system:topo:all -c gridIndividual nodes are identified in the output of stat command by their fully qualified domain name (FQDN). This establishes their "coordinates" and the "domain" to which they belong. Nodes in different domains typically can NOT see each other. Node can be in 1 of 3 states:
POWEROFF Node is Available for use but turned off POWERON Node is Available and is on NOT REGISTERED Node is not Available for use Example: omf stat on the outdoor domain

- It is recommended that the node be in the POWEROFF state prior to any experiment process. If the node is in the POWERON state you can use the omf tell command to get the node into the off state.
omf tell
OMF command to control the power state/reset the nodes.
Usage: omf tell
user@console:omf tell Switch ON/OFF and reboot the nodes in a testbed Usage: omf tell [-h] -t TOPOLOGY -a ACTION [-c AGGREGATE] With: -h, --help print this help message -a, --action ACTION specify an action ACTION: on turn node(s) ON offs turn node(s) OFF (soft) offh turn node(s) OFF (hard) reboot reboots node(s) (soft) reset resets node(s) (hard) -h, --help print this help message -t, --topology TOPOLOGY a valid topology file or description (MANDATORY) -c, --config AGGREGATE use testbed AGGREGATE Some Examples: omf tell -a reset -t node1-1.grid.orbit-lab.org omf tell -a on -t system:topo:all -c grid omf tell -a reboot -t node1-1 omf tell -a offh -t [1..2,1..5] omf tell -a offh -t system:topo:all omf tell -a reset -t system:topo:imagedThe commands are: on, offh (equivalent to pulling out the power cord), offs (software shutdown), reboot (software reboot) and reset (hardware reset).
Example: turn off node1-1 on the outdoor domain

- Once node set is on an POWEROFF state, load an image with omf load command
omf load
Load command is used to put an image onto the hard disk of the node.
Usage: omf load
Install a given disk image on the nodes in a testbed Usage: omf-5.4 load [-h] [-i IMAGE_PATH] [-o TIMEOUT] [-t TOPOLOGY] [-c AGGREGATE] With: -h, --help print this help message -c, --config AGGREGATE use testbed AGGREGATE -t, --topology TOPOLOGY a valid topology file or description (defaults to 'system:topo:all') (if a file 'TOPOLOGY' doesn't exist, interpret it as a comma-separated list of nodes) -i, --image IMAGE disk image to load (default is 'baseline.ndz', the latest stable baseline image) -o, --timeout TIMEOUT a duration (in sec.) after which imageNodes should stop waiting for nodes that have not finished their image installation (default is 800 sec, i.e. 13min 20sec) --outpath PATH Path where the resulting Topologies should be saved (default is '/tmp') --outprefix PREFIX Prefix to use for naming the resulting Topologies (default is your experiment ID) Some Examples: omf-5.4 load omf-5.4 load -t system:topo:all -i baseline-2.4.ndz omf-5.4 load -t omf.nicta.node1 -i wireless-2.6.ndz omf-5.4 load -t omf.nicta.node1,omf.nicta.node2 -i baseline.ndz -o 400 omf-5.4 load -t system:topo:circle -i my_Own_Image.ndz omf-5.4 load -t my_Own_Topology -i baseline-2.2.ndz -t 600 -c grid omf-5.4 load -t my_Own_Topology --outpath ./ --outprefix my_Own_PrefixTwo important arguments are TOPOLOGY describing the set of nodes one wishes to image , and !IMAGE specifying the name of the image one wants to load the nodes with. If the imaging process does not does not finish within the default timeout period, that period can be increase by using the -o flag (e.g. -o 1600). Typical command to load both nodes of sandbox 1 with the baseline image would look like:
If the node is in the NOT REGISTERED state, you may need to wait for it to recover the POWEROFF state (it some times requires a few moments for the services to sync up). If the node takes more than 60 seconds to come out of the NODE NOT AVAILABLE state please report it to an administrator.Example: omf load-i baseline.ndz -t node1-1
