Arif, Several points to clarify:
1. hosts.otherinterfaces will be deprecated for outside using. That means the definition of second interfaces for host will not use hosts.otherinterfaces. But xCAT still uses it inside. Additionally, the hosts table is still been using. 2. Mostly, the nics table should be used to configure the second interfaces (that means not include the primary interface). Maybe someday later, xCAT will support it completely. Even xCAT could support it, the code logic is complicated. 3. Presently, the primary IP of host and BMC should be put in host.ip. 4. Setting the IP of host (primary interface) and IP of BMC in the host.ip is necessary for sequential discovery.

As part of the otherinterfaces in the hosts table allows me to automatically create the hosts file, without having to do it manually, or adding the nodes individually into the nodelist table. i.e. assign the ip to the node, so that it is not cluttered. In the same way, I grasped the idea to do the same thing with the nics table, to not necessarily create the interface on the nodes itself, but to automaticllay create the hosts table, and hence the named configuration I would expect though that the discovery method to lookup a specific value from the ipmi table, and cross check with the nics tables to see what the IP address and and use that as part of the discovery process. correct me if my assumption here on how it should work is wrong. regards, Arif On 16/05/13 15:49, Xiao Peng Wang wrote: Arif, The nics table only can be used to configure the host, but can NOT set the bmc. If you set the attribute nicips.bmc, that means you should have interface named 'bmc' in the host, so that during the boot up of the node, confignics postscript will configure the interface 'bmc' base on the attribute values. Guang Cheng, Please correct me for the usage of nics table.

If you add the entry in the hosts table for the ip of bmc, it would work.

Run 'nodediscoverls -t seq' to display the discovery result. I started the discover by running the following command # nodediscoverstart noderange=node00[1-4] Below is my definition of the node itself. # lsdef node001 Object name: node001 bmc=node001-bmc chain=runcmd=bmcsetup,shell cons=ipmi groups=compute,ipmi ip=10.0.0.1 mgt=ipmi netboot=xnba nichostnamesuffixes.bmc=-bmc nichostnamesuffixes.ib0=-ib0 nicips.bmc=10.0.1.1 nicips.ib0=10.0.2.1 nicnetworks.bmc=xcat_nw nicnetworks.ib0=xcat_ib nictypes.bmc=ipmi nictypes.ib0=infiniband ondiscover=nodediscover postbootscripts=otherpkgs postscripts=syslog,remoteshell,syncfiles power=ipmi serialport=0 serialspeed=19200 I would expect xCAT to grab the IP from the defined IPs in the nics table, and assign this IP.
