e0i not configured after a reboot when using Set-NaNetInterface in advance

[skellner]

After using Set-NaNetinterface regardless of which changes have been applied the rc file looks like this. After a takeover/giveback the e0i Ports or e0a on older systems doesn't come up because it is not configured. It seems that the mediatype parameter prevents that. When I delete the mediatype parameter from the ifconfig e0i* line and issue the command again the port gets configured. Any time you use Set-NaNetInterface the mediatype parameter is added to the ifconfig line again. That's very inconvenient as I use the cmdlet to have the rc file updated automatically.

This seems to happen on systems > Ontap 8.2.3. Is it a new bug with net-config-set-persistent ZAPI like 710228?

I think you might be seeing an undesired result of this fix:  

http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=820862

It looks like why that command fails can be found in the MAN page for IFCONFIG:  

https://library.netapp.com/ecmdocs/ECMP1511537/html/man1/na_ifconfig.1.html

Refer to the statement: "All 1000Base-T devices support autonegotiation and the speed cannot be explicitly set to 1000 Mbps."

I have updated our internal team who worked on resolving the issue in the bug report at the top of this issue you are seeing.

Great,

that's it. Thanks. I wrote a powershell script that changes the rc-file afterwards. Maybe of interest for others

read-nafile /vol/$((get-navolroot).name)/etc/rc | out-file $input_file
get-content $input_file | foreach {
    if ($_ -match "^ifconfig") {
        $out = $_ -replace "(mediatype auto[-_A-Za-z0-9]+\s)",''
        Add-Content -Path $output_file -Value $out
    }
    else {
        Add-Content -Path $output_file -Value $_
    }
}
get-content $output_file

Hi, skellner-san,

Our customer faces the same problem now.

Your report is very useful for us, thank you.

I want to confirm 2 things:

1. Does this bug(?) not fixed yet on 8.2.3?

mcgue-san commented above:

"I have updated our internal team who worked on resolving the issue in the bug report at the top of this issue you are seeing."

Did you get any update of it?

2. The problem was fixed by applying your script?

I'll try to apply it, but I want to confirm that it works right?

Thanks and Regards,

Masaki

Hi Masaki

The issue sounds like BURT 746803. I posted a workaround solution to this here:

Thank you Matt-san,

I'll check your workaround solution.

Thanks and Regards,
