Is it possible to setup HA cluster using 8.1.x 7-mode? Or should I use C-mode instead?
You can setup a "HA Pair" meaning you have two single controllers clustered together, so that in the event of a failure (controller, cable, nic, switch) the other controller takes over.
C-Mode will enable you to cluster multiple "HA Pairs" together, and is pretty much the direction everything is heading. But 7-Mode is perfectly suitable if you only need two controllers in one "HA Pair".
Here is a good NetApp 101 I found
I have two single controllers and want to pair them. Have got NO cf license. I did change the SERIAL_NUMBER and SYSID on the second controller.
A clue of how to do it would be appriciated, thanks!
add a CF license and then type "cf enable"
You can pull your licenses down from support.netapp.com if you bought an HA pair it would come with a CF license
and where is the license? I am using VSIM and the license is not included in the license text file?
Did you find the license you were looking for? I too have a dual controller setup and would like to enable HA but can't seem to find a CF license on the support page.
I find a license for cf : JQIGWWF
I do the change of the S/N on the second node, but I can't still do it working.

Any idea ?
i searched the web and it doesn't seam to be possible to have a ha pair configuration in sim 8.x.x.
