Hi Bruno,
We have similar types of nodes and minimal configuration is required
(RHEL7-derived OS). Install device-mapper-multipath or equivalent
package, configure /etc/multipath.conf and enable 'multipathd'. If
working correctly the command 'multipath -ll' should output multipath
devices and component devices on all paths.
For reference, our /etc/multipath.conf is just these few lines:
defaults {
user_friendly_names yes
find_multipaths yes
}
thanks,
Ben
