single vif creation at production filer

[Raju Mahala]

Hello everybody,

we are planning to configure vif(single mode) so please sugest how to
perform.
below is the plan :-
four ports are available :- 9a 9b 11a 11b
current vif is : vif1(multi mode) -> 9a 11a these ports are from one
switch as a trunck
For redundency we want to take two more ports in trunck mode from
another switch to have another vif called vif2(multi mode) and then
main vif called vif3(single mode) having members vif1 and vif2
so final conf. :
vif1 -> 9a + 11a (currently exists with IP setting)
vif2 -> 9b + 11b
vif3 -> vif1 + vif2
how we can carry out this with minimal intruption. we did it at R200
but that has to be reboot may be due to some problem.

According to me, the easilest way to perform this would be to run setup and make the changes so the RC file would also gets updated and then reboot to check if the RC file has the correct settings.
 

but if you don't want to reboot, then you can also perfom this manually but using the VIF commands and then make the entries in the RC file manually. but you would have to be very careful and ensure that, in case the filer happens to reboot at a later date your RC file has the correct entries otherwise you would have major issues.

 

To execute the RC file without rebooting I guess you could use this command from the telnet session:  /etc/frc

Just out of curious, vif3 will be single mode or multi mode ? I am sure you have multimode configs for vif1 and vif3

 

Kind regards...Avi

Avinash,

vif1 and vif2 will be multi mode and vif3 would be sinle mode having
member as vif1 and vif2.
vif1 will have two ports from one switch as a trunck (which is
requirement for multi vif) and vif2 again two port from another switch
as a trunck.
so if one switch fails storage access remains intact from another
switch.

I did it at R200. I made the entries at /etc/rc file and then rebooted.
I feel it was not safe method as Jay mentioned. Best is to run setup
but our goal is to have as less impact as possible. so wer thinking to
do it online. if one or two minute outage happens then not a problem
because NFS can take that much.
I feel should explore /etc/frc script for safe go so I make entries at
/etc/rc and then run /etc/frc script if it works.

Thanks Jay

Jay if I run setup on running filer then whether it makes changes
online or changes comes in effect after reboot ?

Raju...you have to reboot

What Ever !!!

So it means as long as filer is not rebooted after completing the
setup command, all currently running service will be continue and
there will be no impact on running NFS services. Once it rebooted new
config will come in effect.

Then I think its better because filers are in cluster mode and during
reboot partner will provide the services.
Am I right ?

Yes your right. But be carefull when you run the setup command and configure it as a wrong change can make the services unavailable as the failover process doesnt include the network check.
