Hi Robert, I tried what you suggested, but when I rebooted, the network services went into maintenance mode. Here’s the /usbkey/config file that I had in place before attempting nictagadm. [root@68-05-ca-0a-2f-c5 ~]# cat /usbkey/config # # This file was auto-generated and must be source-able by bash. #
# admin_nic is the nic admin_ip will be connected to for headnode zones. admin_nic=68:5:ca:a:2f:c5 admin_ip=dhcp admin_netmask= admin_network=... admin_gateway=dhcp myricom_nic=0:60:dd:45:73:22 myricom_ip=192.168.2.2 myricom_netmask=255.255.255.0 headnode_default_gateway= dns_resolvers=8.8.8.8,8.8.4.4 dns_domain= ntp_hosts=192.168.1.1 compute_node_ntp_hosts=dhcp I issued the command “nictagadm update -p mtu=9000 myricom” which put the line “myricom_mtu=9000” into that file. Upon reboot is when it went into maintenance mode for network services. I had to remove that line from the console and reboot, at which point it booted up normally.
