Restore an ASM file

Question

Hi,
10g R2 on Unix
I try to copy an Archived log but it fails :
RMAN> run{
2>
4> set archivelog destination to '/home/oracle/';
5> restore archivelog sequence=364825 thread=1;
6> }
using target database control file instead of recovery catalog
allocated channel: CH_1
channel CH_1: sid=467 instance=XXX devtype=SBT_TAPE
channel CH_1: NMO v4.5.0.0
allocated channel: CH_2
channel CH_2: sid=466 instance=XXX devtype=SBT_TAPE
channel CH_2: NMO v4.5.0.0
executing command: SET ARCHIVELOG DESTINATION
Starting restore at 18/05/11
archive log thread 1 sequence 364825 is already on disk as file +DGRE1_FS/archivelog/2011_05_18/thread_1_seq_364825.4013.751421997
restore not done; all files readonly, offline, or already restoredAny solution ?
is it a way to copy a file on ASM into a normal file system ? In ASM commandes I do not see copy :
commands:
cd
du
find
help
ls
lsct
lsdg
mkalias
mkdir
pwd
rm
rmalias
Thank you.

RMAN> copy spfile '+DGDATA_DB/spfilemydb.ora' to '/tmp/afile';
RMAN-00558: error encountered while parsing input commands
RMAN-01009: syntax error: found "spfile": expecting one of: "archivelog, backup, check, controlfilecopy, current, datafile, datafilecopy, keep, (, level, nochecksum, nokeep, reuse, tag"From RMAN you can restore,
You can create pfile/spfile from ASM to non-ASM the pfile/spfile
example
SQL> create spfile='/tmp/spfile.ora' from pfile;
or
RMAN> backup spfile to '<destination>';
