Is is possible to script this on my filer in the lab ( either from the filer itself or from the lab unix machine ) since i have e0a and e0b connected? I thought networking could configure what they need, then I'll just down e0a and up e0b and vice versa.
Guess I'm looking for commands or scripting ideas to use with OnTap and the networking interfaces. Thanks.
You should have a console for this... a serial console or ip console that can connect to the serial console port on the 250. The 250 doesn't have an ethernet console like newer systems (bmc/rlm/sp). THen you can ifconfig e0a and e0b down and up and make changes.
You could look at creating text files with all your commands then source the command file with "source filename" on the controller... if all the commands and timing work out you'd lose console but it would come back when ifconfig is done... once you down the interface you can't ifconfig to bring it up on that network which is down...but with a source file that has the ifconfig new settings it would bring it back...risky but if a lab you can try this. A serial console would be easiest though.
you could write a text file for example source.txt to /vol0/etc with some commands
ifconfig vifname 0.0.0.0 down
vif destroy vifname
ifconfig e0a ip netmask x.x.x.x up
ifconfig e0b ip netmask x.x.x.x up
then type "source -v /etc/source.txt" and it should bring the network back up...but any typos or timing issues will be a risk...so from a console is best but this can work with some testing and low risk since lab setup.
