I logged into the target server where the archives are copied over (by scp) and did the following .. still getting errors

asmcd -p
cp '/u50/thread_2_seq_6664.6373.79999999' '+FRA_STANDBY/2012_10_26/thread_2_seq_6664.6373.79999999'

ASMCMD- 0816 copy source->'/u50/thread_2_seq_6664.6373.79999999' ' and target->'+FRA_STANDBY/2012_10_26/thread_2_seq_6664.6373.79999999'
failed
ORA-15406: ASM file name '+FRA_STANDBY/2012_10_26/thread_2_seq_6664.6373.79999999' is not in single-file creation form
