"show switches" on the master should show the master and the local.
"show switches" on the local should show only the local.
Neither of your devices can reach each other. If the controller ipsec key(s) are entered, it is expected that the controllers would only be able to reach each other through that tunnel. If the keys are wrong, they won't be able to reach each other.
Please try re-entering the keys.
On the master type :
encrypt disable
show running-configuration | begin localip
That will show you the key on the master side. Make sure it matches on the local side.
Also type "show crypto ipsec sa" to see if the ipsec tunnel between controllers is up.
