5.8.4 Switching the Port from Ethernet to
InfiniBand
Make sure that you have started the Mellanox Software Tools (MST) as explain in the
section Starting the Mellanox Software Tools
, and have identified the correct ports to
change.
1. Change the configuration for the network cluster ports to InfiniBand by setting
LINK_TYPE_P1=1 for each port.
The following example configures all 8 network cluster ports.
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf0 set LINK_TYPE_P1=1
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf1 set LINK_TYPE_P1=1
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf2 set LINK_TYPE_P1=1
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf3 set LINK_TYPE_P1=1
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf4 set LINK_TYPE_P1=1
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf5 set LINK_TYPE_P1=1
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf6 set LINK_TYPE_P1=1
~$ sudo mlxconfig -y -d /dev/mst/mt4119_pciconf7 set LINK_TYPE_P1=1
2. Verify the configuration changes have been applied.
$ sudo mlxconfig query | egrep -e Device\|LINK_TYPE
