Re: [xcat-user] [External] Sequential-based discovery when BMC is on management network

[Er Tao Zhao]

Hi, 

 

Yes, the document you mentioned below use the separated BMC/Host network scenario.

But it  works if you set the desire BMC in the same subnet with Host.

 

So, change this line when you follow the document:

 

chdef cn1 mgt=ipmi cons=ipmi ip=10.0.101.1 bmc=<another_ip_in_host_subnet> netboot=petitboot installnic=mac primarynic=mac

Pls let us know if there is any more issue.

 

BTW, it is possible to let us know what kind of server you are managing? What is the size of the cluster? What is the purpose of this cluster?

 

Thx!

Best Regards,

xCAT discovery only discover things that PXE boot (unless explicitly running bmcdiscover).  If the BMC is shared port, it's fine because the MAC that does PXE is not the BMC.

Hello,
 
We have some machines with shared BMC on the first network interface.
 
On other cluster management softwares - Rocks for instance - things get really messy when BMC is discovered as a compute node during the process.
 
So, how xCAT handles this scenarios? It properly discovers the BMC as a BMC device or it should be done with some kind of intervention?
 
I took a look at the docs but it only covers scenarios with a segregated BMC network: https://xcat-docs.readthedocs.io/en/stable/guides/admin-guides/manage_clusters/ppc64le/discovery/seq_discovery.html
 
Thanks,
