NetApp Losing IP Config After Reboot


If your interfaces are losing configuration you must edit the /etc/rc file. The filer uses this file at boot for settings. You can change this file by:

1.Running setup again.
2. Edit etc rc file

*****Makes sure you read the /etc/rc file into memory first using:   rdfile /etc/rc *****

CAUTION: If you make a change using wr file and you have NOT run the rdfile command first you will delete the original rc file. 

I would reccomend copying the return of the rdfile command to a notepad just in case.

The command to append your changes to the rc file is:     wrfile -a /etc/rc

**Example RC File**

hostname SAN1
vif create multi Prod1 -b ip e0a e0b
ifconfig Prod1 `hostname`-Prod1 mediatype auto netmask 255.255.255.0 partner Prod2
route add default 10.10.20.1 1
routed on
options dns.enable off
options nis.enable off
savecore

**Example command to append an interface configuration to the file

wrfile -a /etc/rc ifconfig e0P 10.10.10.31 netmask 255.255.255.0 mediatype auto

** Example of the rdfile output after running wrfile -a

hostname SAN1
vif create multi Prod1 -b ip e0a e0b
ifconfig Prod1 `hostname`-Prod1 mediatype auto netmask 255.255.255.0 partner Prod2
route add default 10.10.20.1 1
routed on
options dns.enable off
options nis.enable off
savecore
ifconfig e0P 10.10.10.31 netmask 255.255.255.0 mediatype auto
