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.
