Re: [xcat-user] confignics -s -r not removing ib0

Hi Javier,
 
Here I tried to clarify your real actions. Could you want to use `confignics` to remove configured nics, then re-configure nics configured in nics table including IB nics? 
 
If the answer is yes, I think you can use scripts order like "confignics -s -r; confignetwork --ibaports=2". "confignics -s -r" will configure install nic and remove some other nics, "confignetwork --ibaports=2" will configure all nics configured in nics table including IB. When "confignetwork --ibaports=2" start to configure IB (--ibports number depends on your own case), it will remove old IB configuration from the compute node, then start to configuration based on nics table.
 
So you do not need to consider using `confignics` to remove IB adapter from compute node before configuring IB, it removes old configuration every time. I carefully check `confignics`, you are right, the "confignics -s -r not removing ib0".
 
You may notice that `confignics` is deprecated in the doc, the new script is `confignetwork`. We noticed that `confignics -r` always make user confuse about `In which scenario, confignics can remove nics?`, so we let user to modify the updates by themselves, `confignetwork` will not do remove work. The old `confignics` is kept here, but we suggest use confignetwork.
 
 
Best Regards

Hi Yuan,

 

There are several other Ethernet devices that are undefined & do get removed (maybe removed is wrong, just not configured) whilst deploying & specifying in the postbootscripts :confignics -s -r

however ib0 gets a config file (but is not enabled) & that causes an error when the network service is loaded

 

tabdump shows:#

 

"host1",,,,,,,,"enp6s0f0!MTU=9000",,,,
"host2",,,,,,,,"enp6s0f0!MTU=9000",,,,
"host3",,,,,,,,"enp6s0f0!MTU=9000",,,,
"host4",,,,,,,,"enp6s0f0!MTU=9000",,,,
 

 

 

Kind Regards

Hi Javier,
 
`confignics -r` is only works in this scenario: If the compute node’s nics were configured by confignics and the nics configuration changed in the nics table, user the confignics -r to remove the undefined nic.
 
 
 
That means: IB interface should be configured by `confignics` at the beginning. When you delete IB interface from nics table, `confignics -r` should work.  Could you use `tabdump nics` to check your nics table? If it does not work, could you open a issue and describe your steps ?
 
 
Best Regards

Hello,

 

I am hoping someone can help.

Deploying a host with xcat & the ib0 adapter config file is not being removed

 

 

 

running:

updatenode nodename -P 'confignics -s -r'

 

produces below output:

 

nodename: confignics on nodename: executed script: 'configib -r' to remove all ib nics and configuration files
nodename: nothing to do.

 

 

This is coming from the configib script, but does not remove the ib0 config file from network-scripts

 

 

 

#if $NIC_IBNICS is not defined, all ib nics' configuration files will be deleted.
if [ -z "$NIC_IBNICS" ]; then
    echo "nothing to do."
fi
