How can i make a APIC to a factory default ?

In case fabric domain name mismatch, the mismatched APIC under a APIC cluster can be handled by console and GUI.

I've checked a lot of documents regarding APIC troubleshooting but i couldn't find it.

I think i have to do initial setup to put it on APIC cluster. 

Could you tell me What i should do?

If the APICs were ever successfully converged into a cluster, rescue-user will use the password of the cluster. if the APICs never formed a cluster then rescue-user will not have a password if I'm not mistaken, so yes i believe that would solve your problem. 

If you noticed during the initial setup script, only APIC-1 asked for a password, subsequent APICs are assumed to become cluster members after fabric discovery and password is exchanged to all other APICs for local authentication purposes. if the fabric is never discovered and the APICs do not negotiate the password, then rescue-user will not have a password.
