haneshparag — Wed, 04 Jun 2025 16:09:49 GMT

Please may you help?

I have created a vif lacp and succesfully added the changes to the /etc/rc file.

#Auto-generated by setup Fri Aug 2 18:46:55 GMT 2013
hostname ED-STRG-DR
ifgrp create multi VIF_1DR -b ip e0d e0c
ifgrp create lacp vif0 -b ip e0a e0b
ifconfig VIF_1DR `hostname`-VIF_1DR netmask 255.255.255.0 mtusize 1500 trusted wins up
ifconfig vif0 `hostname`-vif0 -b ip e0a e0b netmask 255.255.255.0 mtusize 9000
ifconfig vif0 10.10.20.1 mediatype auto netmask 255.255.255.0 mtusize 9000
ifconfig e0a flowcontrol full
ifconfig e0b flowcontrol full
ifconfig e0M flowcontrol full
#route add default NONE 1

Hi @haneshparag

Have you entered the ip address entry in /etc/hosts file like below example.

example : 10.10.20.1 fas01-vif0

ifgrp create lacp vif0 -b ip e0a e0b
ifconfig VIF_1DR `hostname`-VIF_1DR netmask 255.255.255.0 mtusize 1500 trusted wins up
ifconfig vif0 `hostname`-vif0 mediatype auto netmask 255.255.255.0 mtusize 9000

Please modify linke the above. Please let me know that is it a HA pair or stand alone controller.?

If it is HA-pair than you need to create ifgrp on partner also and need to add like below

Hi Naveenpusuluru,

Thanks for getting back, this is standalone controller setup. The 192.168.10.x network (which is live) was not configured correctly, hence the need for a lacp jumbo frame setup.

1. My Host File is configured as follows:

ED-STRG-DR> rdfile /etc/hosts
#Auto-generated by setup Fri Aug 2 18:46:55 GMT 2013
127.0.0.1 localhost localhost-stack
127.0.10.1 localhost-10 localhost-bsd
127.0.20.1 localhost-20 localhost-sk
# 0.0.0.0 ED-STRG-DR-e0M
# 0.0.0.0 ED-STRG-DR-e0P
# 0.0.0.0 ED-STRG-DR-e0b
# 0.0.0.0 ED-STRG-DR-e0c
# 0.0.0.0 ED-STRG-DR-e0d
192.168.10.158 ED-STRG-DR-VIF_1DR
10.10.20.1 ED-STRG-DR-vif0

ED-STRG-DR>

2. ETC/RC file

If I remove the

ifconfig vif0 10.10.20.1 mediatype auto netmask 255.255.255.0 mtusize 9000 from the etc/rc, system manger will alert with the issue attahced

Hence my confusion on how to confgure the rc file

Hi @haneshparag

Please modify the rc file and host file like below.

Host file :

#Auto-generated by setup Fri Aug 2 18:46:55 GMT 2013
127.0.0.1 localhost localhost-stack
127.0.10.1 localhost-10 localhost-bsd
127.0.20.1 localhost-20 localhost-sk
# 0.0.0.0 ED-STRG-DR-e0M
# 0.0.0.0 ED-STRG-DR-e0P
# 0.0.0.0 ED-STRG-DR-e0b
# 0.0.0.0 ED-STRG-DR-e0c
# 0.0.0.0 ED-STRG-DR-e0d
192.168.10.158 ED-STRG-DR-VIF_1DR
10.10.20.1 ED-STRG-DR-vif0

rc file :

#Auto-generated by setup Fri Aug 2 18:46:55 GMT 2013
hostname ED-STRG-DR
ifgrp create multi VIF_1DR -b ip e0d e0c
ifgrp create lacp vif0 -b ip e0a e0b
ifconfig VIF_1DR `hostname`-VIF_1DR netmask 255.255.255.0 mtusize 1500 trusted wins up
ifconfig vif0 `hostname`-vif0 mediatype auto netmask 255.0.0.0 mtusize 9000
ifconfig e0a flowcontrol full
ifconfig e0b flowcontrol full
ifconfig e0M flowcontrol full
#route add default NONE 1 ---> route add default 192.168.10.1 1(it will be like this)
routed on
options dns.enable off
options nis.enable off
savecore

For vif0 ip configuration you have mentioned wrong subnet. You are assigning 10.10.20.1, means this is class A ipaddress. Please take subnet from your network team for this ip. Normally it will be 255.0.0.0

One more thing i have noticed from your rc file is you guys have not configured default gateway. You need to configure it in order to other networks outside data center to communicate with netapp box(for remote login .... etc).

Trust me i have configured these rc and host files alot. Please modify your rc file like the above.

Please post me the output of below command here.

route -s

The error what you are seeing in tools is due to recent configuration changes you made on rcfile and host file. Please reboot the system once you cnfigured everything. This error will be washed away.

Hi @haneshparag

If you are using two different networks then you need to add the route again like below.

route add 10.10.20.1 192.168.10.1 1

However, the rc file is still giving me problems.

I tried changing the netmask from 255.255.255.0 to 255.0.0.0 but still the system manger reflects 255.255.255.0

I am wondering if the config in memory and the rc file are not synchronising? No matter what change I do in the rc file, there is always an alert issue by the system manager!

Here is the ifconfig -a

Hi @haneshparag

After making changes in rc file, just reboot the node. So what ever changes you made in the rc file will reflect.

Please configure default gateway and also make sure that your SP(rlm) ip address and root password with you before rebooting the controller.
