Luis,
Please visit the documentation page:
http://sourceforge.net/apps/mediawiki/xcat/index.php?title=XCAT_Documentation
and pull up the xCAT iDataPlex Cluster Quick Start
If you follow this guide, running getmacs manually is not required.
Autodiscovery magic should take over and do it for you, this includes the
programming the IMM.
We are following that guide, but, in our case (surely, it's our failure
configuring something) the Autodiscovery magic don't work, or it work
randomly (only one node get the mac configured, and no node get the rigth
IP). And I don't know how to fix it.
Main problems:
* How I set a node to new state? I want a node that I test to install, to
start again.
/opt/xcat/share/xcat/tools/rmnodecfg
# ./rmnodecfg n1 – n10
I tried (noderm nodeXX ; nodeadd node6 groups=ipmi,idataplex,compute,all
), but it did not start in discovery state again.
* How can i test that the switch is cofigured for autodiscovery? There is
something I can manually do, similar to the xCat proccess to check if a
node is plug in the rigth position.
You could try snmpwalk to see how the port for a particular switch is
defined.
What type of switch are you using. I am not familiar with setting such as
Ethernet7 ?
This was posted in xcat a while back but can give you an example:
As an example, we had an IBM j48e gigabit switch that wasn't discovering
correctly. We ran:
snmpwalk -v 1 -c public j48 .1.3.6.1.2.1.31.1.1.1.1 | less
The output shows the port we're looking for (port 5) is:
IF-MIB::ifName.512 = STRING: ge-0/0/5
IF-MIB::ifName.512 = STRING: ge-0/0/5.0
We found that the mac was on the 5.0 interface, so it seemed to match all
of those. Inside of our switch table we put:
node0342,j48,ge-0/0/5.0
This then allowed autodiscover.
* Why a node is not getting the rigth IP, even when it have the
autodiscovery MAC rigth. e.g, node7 is installed with IP 10.22.1.249 with:
What does your switch tab look like, could be that it doesn't
understand Ethernet7 setting for port 7?
