message on takeover "Unable to determine primary for interface e0a"

[ol15]

helllo,

on filer NetApp Release 8.2.3P6 7-Mode

i have a message for each interface when i test a "cf takeover"

Wed Jan  6 13:32:46 GMT [xxxxxa:net.ifconfig.noLocal:error]: ifconfig: Unable to determine primary for interface e0a.
Wed Jan  6 13:32:46 GMT [xxxxxa:net.ifconfig.noLocal:error]: ifconfig: Unable to determine primary for interface e0b.
Wed Jan  6 13:32:46 GMT [xxxxxxa:net.ifconfig.noLocal:error]: ifconfig: Unable to determine primary for interface e0c.
Wed Jan  6 13:32:46 GMT [xxxxxxxxa:net.ifconfig.noLocal:error]: ifconfig: Unable to determine primary for interface e0d.

what does mean those messages ?

here is the first line of the two filers /etc/rc:

#Auto-generated by setup Wed Dec  9 11:09:35 GMT 2015
hostname xxxxx
ifconfig e0a mtusize 9000
ifconfig e0b mtusize 9000
ifconfig e0c mtusize 9000
ifconfig e0d mtusize 9000
ifconfig e0M `hostname`-e0M netmask 255.255.255.224 mtusize 1500 partner e0M

You have no proper partner configured in rc file, and also, is your host file configured?

hello

thanks for your reply

i have this message since i had the four primary lines

ifconfig e0a mtusize 9000
ifconfig e0b mtusize 9000
ifconfig e0c mtusize 9000
ifconfig e0d mtusize 9000

without those files on my rc file, there is no error messages , but after a takeover and a giveback the mtusize pass from 9000 to 1500 so i had those 4 lines on the rc files and now i have this new message ""Unable to determine primary for interface e0a""

see below the /etc/rc files

You already set MTU for each logical interface; why do you need to do it for physical interfaces as well? You do not use them directly.

[JGPSHNTAP]

Also, i'm a bigger fan of LACP vs. Multi.  LACP is much more robust.

hello,

i must put those 4 lines because:

without those files on my rc file, there is no error messages , but after a takeover and a giveback the mtusize value change from 9000 to 1500 so i had those 4 lines on the rc files and now i have this new message ""Unable to determine primary for interface e0a""

i have to use mutli cause switchs didn't supports lacp

Where are you IP definitions from filer B

Also, in the ifconfig statement of the vif for the IP, you should put the MTU size, no on t he individual interface..

And, please review TR-3802 for ethernet best practices

hello,

change :

ifconfig e0a mtusize 9000
ifconfig e0b mtusize 9000
ifconfig e0c mtusize 9000
ifconfig e0d mtusize 9000

by

ifconfig e0a flowcontrol full mtusize 9000
ifconfig e0b flowcontrol full mtusize 9000
ifconfig e0c flowcontrol full mtusize 9000
ifconfig e0d flowcontrol full mtusize 9000

then no messages like : "unable to ....e0a"

regards
