Re: [SGE-discuss] Compute nodes not coming back on line

2018-10-26 Thread Zorger, Richard
Hello,

Our nodes can now see rest of the network but still are not booting to Rocks. 
The movers had not cabled the port connecting the enclosure to the network. 
Luckily I had snapped a picture of the wiring before the move.

Now I can ssh from the head node to each compute node via its name or IP 
address. However when I boot them they are not finding the head node to load 
SGE, even if I force them to use PXE. I have tried PXE booting from both the 
console and the Open Management Controller from the enclosure.

What are some troubleshooting steps I could try?

thanks

Does the headnode have two network interfaces? One for the utside world and one 
for inside the cluster?
