hi Jarrod,

Did your team verified rhels7.5 diskless on x3850? Do you have any thought on how to debug this? thanks

Hi Sam,

From the http log, the root image tarball bas been downloaded successfully, the system boot up hang while switching root to the uncompressed root image directory, not just lost console.

have you tried the suggestion from Michael Robber and David Johnson?

the “hard” needs to be nulled out, that is setting hardware flow control…

when you "

tried removing the cons setting, to no avail

", did you rerun nodeset to apply the change?

Now we do not have any IBM x3850 X5 machine on hand, let's ask the lenovo staff in the list to see whether they have any suggestion

SSH Attempt:

ssh: connect to host node01 port 22: No route to host

I did a fresh reboot to ensure I got everything and only that which is applicable.

hi Sam,

the status is "netbooting", means the provision process has stepped over the initrd boot phase and in the root image boot up process. If only console is lost, the following boot up steps can still continue, what happens if you try to ssh the node?

and what is the last entries you see in the /var/log/httpd/access_log on MN when the provision hang?

thanks

~]# lsdef node01 -i status

Object name: node01

status=netbooting

Also, when we try to use rcons on the machine we get the following error:
~]# rcons node01

[Enter `^Ec?' for help]

Acquiring startup lock...done

Info: SOL payload already de-activated

Info: SOL payload disabled

I have tried removing the cons setting, to no avail. The console settings are “115200”.

Group entry from the nodehm table: “"ipmi","ipmi","ipmi",,,,,"0","115200","hard",,,,,,”

Thank you all,

Sam

Hello,

I am trying to setup a new HPC cluster using XCAT (2.14). I have installed the management node and created the boot image (RHEL 7.5). The node has been discover and PXE boots, downloading the image file. But the boot process stalls and never finishes. I have even copied over a working RHEL 7.3 image from our other cluster to see if that is the issue. I’ve tried disabling and enabling hyperthreading in the client machine. I’ve also updated the firmware on the client machine. Does anyone have any ideas of what I might try next?

Node Hardware

IBM x3850 X5

256 GB RAM

Machine Type 7143 AC1

4 x Intell Xeon E7 4820
