OpenHPC: Setup the IPMI BMC Network in OpenHPC

Add the Warewulf IPMI module

 yum install warewulf-ipmi-ohpc
# rebuild the VNFS to include the IPMI init scripts 
 wwvnfs -y --chroot=/opt/ohpc/admin/images/centos7.2-hfi/

Now add the IPMI modules to the nodes

• Assumes compute nodes have already been added

# Example
    wwsh -y ipmi set ${c_name} --autoconfig=1                \
                               --ipaddr=${c_bmc[$i]}         \
                               --netmask=${bmc_netmask}      \
                               --username="${bmc_username}"  \
                               --password="${bmc_password}"

# In practice / quick script. there will be better ways
#!/bin/bash

for ((i=2; i<10; i++))
do
        echo "wwsh -y ipmi set node00${i} --autoconfig=1 --ipaddr=10.10.10.10${i} --netmask=255.255.255.0 --username=ADMIN --password=ADMIN"
done

for ((i=10; i<=52; i++))
do
        echo "wwsh -y ipmi set node0${i} --autoconfig=1 --ipaddr=10.10.10.1${i} --netmask=255.255.255.0 --username=ADMIN --password=ADMIN"
done

Check and confirm the IPMIs are configured

[root@head ~]# wwsh ipmi list
