If you are configuring them with oVirt, you could also make a after_network_setup hook that did as below. > > #!/bin/sh > echo connected > /sys/class/net/ib0/mode > echo connected > /sys/class/net/ib1/mode > > Markus > > > - Trey > > > > On Oct 19, 2014 10:11 AM, "Arman Khalatyan" <[email protected]> wrote: > > > > > > Hi, > > > > > > I need to add following line in the hosts ifcfg-ib0 interface: > > > > --------------------------------------- > > CONNECTED_MODE=yes > > > > MTU=65520 > > > > IPV6INIT=no > > > > --------------------------------------- > > From the web Interface I can change only custom MTU. > > > > IB interface supports big MTUs only if it is in the "connected mode". > > > > > > Are there way to set it during the deployment/upgrade process? > > Thanks, > > Arman. > > > > > > > _______________________________________________ > > Users mailing list > > [email protected] > > http://lists.ovirt.org/mailman/listinfo/users > > > > > > > > > > _______________________________________________ > Users mailing list > [email protected] > http://lists.ovirt.org/mailman/listinfo/users > _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
