Setting up Power Control

Power control can be configured once all of the managed servers have been added successfully and the network interfaces have been updated. To do this, install fence-agents-vbox on the adm node and on all of the server nodes:

vagrant sh -c "sudo yum install -y fence-agents-vbox" adm oss1 oss2 mds1 mds2

Next, ssh into the adm node and install the “fake” IPMI hardware:

cd /usr/share/chroma-manager
python scripts/fake_ipmi_vbox.py
    # Enter "10.0.2.2" for the IP
    # Enter your computer username
    # Enter your computer password

Note There is currently a bug that causes the fake_ipmi_vbox.py script to fail on the first run; the process will hang indefinitely.

To fix this, hit ctrl+Z to suspend the process.

Next, run ps aux | grep "fake_ipmi" to get the process number and kill the process by executing, kill -9 <processId>.

Once the process has been destroyed,

Navigate to Configuration->Power Control. Add the following entries for each server:

Server PDU
mds1.lfs.local mds1
mds2.lfs.local mds2
oss1.lfs.local oss1
oss2.lfs.local oss2

Initially, each entry will highlight with a light orange background. Wait for 30 seconds and refresh the page; each entry will now be green. Your power control is now setup.
