Mike, Use this as an example:
> ro ramdisk_size=40000 cio_ignore=all,!condev > ip=10.16.105.69::10.16.111.254:21:train6.redhat.com:enccw0.0.0600:none > rd.znet=qeth,0.0.0600,0.0.0601,0.0.0602,layer2=0,portname=FOOBAR > nameserver=10.16.46.224 nameserver=10.16.36.29 > rd.dasd=0.0.0100 rd.dasd=0.0.0101 > inst.repo=http://10.13.145.5/rhel7_s390/ or > inst.repo=nfs:[options:]server:/path > vnc vncpassword=redhat Where: The documentation explains the semantics of all the bits and pieces: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/chap-anaconda-boot-options.html#list-boot-options-network The upstream docs might explain the double colon, which is just an optional "peer" option that is not needed in our case: https://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html#_network "ip=<client-IP>:[<peer>]:<gateway-IP>:<netmask>:<client_hostname>: <interface>:{none|off|dhcp|on|any|dhcp6|auto6|ibft}:[:[<mtu>][:<macaddr>]] " or "ip=<client-IP>:[<peer>]:<gateway-IP>:<netmask>:<client_hostname>: <interface>:{none|off|dhcp|on|any|dhcp6|auto6|ibft}[:[<dns1>][:<dns2>]] " "<peer> is optional and is the address of the remote endpoint for pointopoint interfaces" If one does not follow the ip= syntax to the very last detail, it just fails (or falls back to dhcp) without helpful user message [see more recent pre-validation comments of bug 1070104]. or Try Neale suggestion - it also worked :-) Kind Regards, Filipe On Sep 16, 2014, at 1:39 PM, Michael MacIsaac <[email protected]> wrote: > Neale, Felipe, > > Thanks for the quick replies.
