Multipath is not configured as part of the Oracle Linux KVM installation. However, to help ensure that the PowerFlex device is not blocked, the following command needs to be run on each Oracle Linux KVM host, to create a powerflex.conf file.
mkdir -p /etc/multipath/conf.d
vi /etc/multipath/conf.d/powerflex.conf
blacklist_exceptions {
devnode "scini*"
}
