RMAN-06189: after recovering controlfiles

Hello.

I have the following scenario:

I have databases A and B.

I want to restore A on B.

When trying to restore controlfile and startup mount I get RMAN-06189. What I'm I doing wrong? I kept the original spfile on B.

RMAN> shutdown immediate;

database dismounted
Oracle instance shut down

RMAN> startup nomount;

connected to target database (not started)
Oracle instance started
