Re: [xcat-user] Hello Newbie who need some help. - Benjamin.
Hi Benjamin, It has been several years since I tried installing on VBox, and not all the instructions make sense to me any longer, but here is what little I had documented from my install: Note: The node 'vh01' below is put for the computer that you are running VBox on (desktop, laptop, etc.) Add your nodes so that they can work with the Virtual Box plugin. nodeadd node1 groups=testgrp,vboxgrp vm.host=vh01 Followed by: chtab node=vboxgrp nodehm.mgt=vbox nodehm.power=vbox That tells the nodehm table what settings to run for the nodes in the vboxgrp group so that they can properly run as VM nodes in VirtualBox. Then add the host computer vh01 as a node (your port number may be different): nodeadd vh01 groups=websrv websrv.port=18083 websrv.username=test websrv.password=test chtab node=vh01 hosts.ip=IP of vh01 hosts.comments=“The host running VBox” Manually set the MAC addresses in the mac table. Finally you must launch the VirtualBox webservice on the physical host machine. You may first want to execute (I don't remember why I made this note, or what problem it solves): VBoxManage setproperty websrvauthlibrary null Then when you are prepared to launch the webservices run in a separate shell (it must remain open running) or in the backgroud: vboxwebsrv Final note to resolve an issue with a VM's name as shown in VirtualBox and the hostname of the xCAT node being named the same thing (which you would think wouldn't be a problem): “Sometimes the VirtualBox machine name can not equal the xCAT node name, especially in test cases that might occur. There is a feature for this situation: add somewhere in the comment field of the vm table a schema like vmname:NAME! and replace NAME by the vm name on the VirtualBox host system. You may insert other comments before and after that schema. For example the xCAT node vm03 should point to the virtual machine machine03 on the VirtualBox host vh01.” (This “trick” was absolutely necessary for me - else the rpower command would not work) Example config in vm table: node1,vh01,,,vmname:xCat_Node1!, I hope maybe that helps. That's all I've got. :-) Best regards, Josh Nielsen On Tue, Aug 4, 2015 at 6:21 PM, Benjamin LIPERE benjamin.lipere...@gmail.com wrote: Hello. I am a newbie with XCAT.

[xcat-user] Hello Newbie who need some help. - Benjamin.
Hello. I am a newbie with XCAT. I am a little lost on the installation. Can some one help me to start on XCAT with a VirtualBox Cluster, please, step by step, and by e-mail of course ??

[xcat-user] Autodiscovery for HP Cluster - SNMP iLo Question
Hello, We are planning to use xCAT to deploy ESX on an HP BladeSystem c7000 cluster (BL460C Gen 9 blade servers). For the time being I was going to skip iLo setup since I am confused about how to get that working with xCAT. However, what I want to know is if I can still do autodiscovery of our nodes as long as the nodes are defined in the switch table and the switches have SNMP enabled. The documentation available online sends mixed signals about this. Sumavi's documentation seems in some places to suggest that SNMP being enabled is the only critical component for autodiscovery: *So you may not have the ability to have SNMP read access to the network switches to do autodiscovery. Not a problem. You'll just have to fill in the MAC addresses yourself.* (From: http://sumavi.com/sections/skipping-autodiscovery) Elsewhere it also seems to suggest SNMP is all is needed: *If xCAT doesn't know who the node is, then it will automatically run the autodiscover code. This code looks through all the switches in the switch table trying to map the port to the mac to the node. It does this by running snmpwalk commands through the switches.* But then it disappointingly (and possibly outdated-ly) says: *Autodiscovery has not been tested with HP blades. Therefore, you are better off just running getmacs when these nodes are defined to map the mac address*. (From: http://sumavi.com/sections/understanding-autodiscovery) But then elsewhere it says this, which seems to imply that the management module is needed for autodiscovery, and not merely SNMP: *In order to automate discovery for IPMI and iLo nodes there needs to be a mapping of nodes to switch ports. This relationship is defined in the switch table. The methods, passwords, etc to communicate with the switches is in the switches table. Notice that with blades this step usually isn't necessary. xCAT can discover IBM blades through the management module.* (From: http://sumavi.com/sections/switch-and-switches) Is this perhaps only talking about the nodeX-bmc definition in regards to autodiscovery and not the base nodeX definition itself? My main question is, based on the above, if SNMP and the management module both have a part to play in autodiscovery is there any chance that HP Blades can work with discovery, as long as I explicitly map the nodes to port numbers in the switch table? Will I have to configure iLo to make autodiscovery work or can I leave iLo alone and just enable SNMP and configure the switch table?
