how to change an ip of a virtual interface and name of a filer NetApp Release 8.2.3P3 7-Mode

wissem — Wed, 04 Jun 2025 12:06:40 GMT

Hi i need to change the name and the ip of a vif interface on a 7-mode netapp filer could you please advise me on the best way first i m thinking of editing /etc/hosts with wordpad by cifs acess

name:f-ammout new name f-ammout_old

vif inteface: giga0

here content of hosts file ...

127.0.0.1 localhost

old_ip f-ammout f-ammout-giga0

... so by changing it like

new ip f-ammout_old f-ammout_old-giga0

save the file with wordpad then editing rc file

content of rc file ...

#Regenerated by registry Thu Aug 02 10:27:43 EEST 2012

hostname f-ammout

timezone Europe/Istanbul

vif create single giga0 e0a e0b

....

savecore ...

so changing on the rc file only the hostname like below

hostname f-ammout_old

and save the file

then by console launching command

hostname f-ammout_old

now changing the ip of the vif interface giga0 online to block acess to the old filer to users and do some stuff

ifconfig giga0 down

ifconfig giga0 0.0.0.0

ifconfig giga0 new_ip

ifconfig giga0 up

then after stuff done reboot the filer

can you please tell me is this a correct steps for the opération ?

Hi,

Your instructions are almost good.

To make changes permanent across reboot on filer : rc & hosts file must be edited

ssh to filer:

filer>rdfile /etc/rc [copy paste into notepad wordpad is not necessary]
Once changes are made in the notepad, write it out!

filer>wrfile /etc/rc
example change:
ifconfig vif0 `hostname`-vif0 blah blah

Press ctl+c to commit the changes.

Repeat the same for /etc/hosts as well.

2) /etc/hosts
example change:
IP_ADDRESS <HOSTNAME>-vif

Also, to change filer name:
a) Add the new_name entry into the /etc/hosts file
b) filer>hostname new_name

It will immediately reflect.

To reflect the IP change while the FILER is ON:
filer>ifconfig vif0 <NEW IP ADDRESS> netmask <NEW SUBNET MASK>

Note: Any changes made with 'ifconfig' command are not persistent across reboot, and therefore they must also be added to rc & hosts file. Reboot is not necessary but if the filer reboots in future, it will retain the settings/changes you have made.
