I am sorry I didn't make myself understood correctly, but I certainly know we cannot pair a vsim with a physical node to create an HA.
Now let me make it clearly: assume that I got a FAS2240A, and I use one controller to create a single-node cluster, and just leave the other controller not configured(but with 8.2 cDOT image installed). Now I want to convert the single-node cluster to pair the unused controller to create an HA pair cluster. what is the specific conversion processes?
I got what I want to know, thank you so much for your input.
Actually it was a simulator(8.2 cDOT) environment, and I use one vsim to create a single-node cluster, and I want to convert this single-node cluster to a two node cluster by adding another vsim, I just didn't know how to do this.
