Here is a quick one for you— one of our customers asked me today how to selectively stop the RDMA service on hosts within a Bright Cluster Manager node category that don't have Infiniband. Here it is, a very fast and easy solution when using the CMSH.
[hcsd-head]% device use node001
[hcsd-head->device[node001]]% set finalizescript
# turn off rdma service on hosts without Infinband
lspci | grep -i $module | grep -v grep >/dev/null 2>&1
if [ $res == 0 ]; then
chkconfig rdma off
