this is NORMAL status for ASM instance. there is a special flag the agent passes to the listener to allow it to connect to an ASM instance. If you are curious, the flag is (UR=A) to the tns entry.
I assume the ASM entry that you are showing refers to what should be in db_1/network/admin/tnsnames.ora?
My tnsnames.ora does not have an ASM entry at all, and I am experiencing the same issue as the original poster. Should I add one and restart ?
