ORA-15046: ASM file name is not in single-file creation form

We got an below error copying the file from the existing ASM location to the New ASM Disk as shown below

ASMCMD> cd +FRA/RACDBN1/BACKUPSET/2020_12_16/

ASMCMD> ls
nnndn0_FRIDAY_LEVEL_0_0.333.1059285491

Need to copy the above file to new asm disk

ASMCMD> cp +fra/RACDBN1/backupset/2020_12_16/nnndn0_FRIDAY_LEVEL_0_0.333.1059285491 +backup/fdbbkp/

copying +fra/RACDBN1/backupset/2020_12_16/nnndn0_FRIDAY_LEVEL_0_0.333.1059285491 -> +backup/fdbbkp/nnndn0_FRIDAY_LEVEL_0_0.333.1059285491
ASMCMD-8016: copy source '+fra/RACDBN1/backupset/2020_12_16/nnndn0_FRIDAY_LEVEL_0_0.333.1059285491' and target '+backup/fdbbkp/nnndn0_FRIDAY_LEVEL_0_0.333.1059285491' failed
ORA-15056: additional error message
ORA-15046: ASM file name '+backup/fdbbkp/nnndn0_FRIDAY_LEVEL_0_0.333.1059285491' is not in single-file creation form
ORA-06512: at "SYS.X$DBMS_DISKGROUP", line 617
ORA-06512: at line 3 (DBD ERROR: OCIStmtExecute)

Note: The above cp command failed due to the ASM file name was not in a form that can be used to create an single file, here the file name should not contain the file number/incarnation.

To overcome this issue, remove the number/incarnation from the file and copy as shown below

ASMCMD> cp nnndn0_FRIDAY_LEVEL_0_0.333.1059285491 +backup/fdbbkp/nnndn0_FRIDAY_LEVEL333
copying +fra/RACDBN1/backupset/2020_12_16/nnndn0_FRIDAY_LEVEL_0_0.333.1059285491 -> +backup/fdbbkp/nnndn0_FRIDAY_LEVEL

Hence copyied successfully.

Verify

ASMCMD> cd +BACKUP/FDBBKP

ASMCMD> ls
nnndn0_FRIDAY_LEVEL333

Note: In case if you have the multiple files to copy, Use the excel to create number of files in correct format.
