I got ” ORA-15001: diskgroup “DATA” does not exist or is not mounted | ORA-15018 ORA-15001 RMAN-06956 ” error in Oracle database.

ORA-15001: diskgroup “DATA” does not exist or is not mounted | ORA-15018 ORA-15001 RMAN-06956

Details of error are as follows.

RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 12/02/2020 17:12:11
ORA-01119: error in creating database file '+DATA'

The ORA-15018 ORA-15001 RMAN-06956 error is related with the permission issue.

Issue is related to permission issue, check and fix it .

The Grid home  is owned by oinstall

ls -lrt /<oracle home>/bin/oracle




-rwsr-s--x 1 oracle oinstall 327811823 Oct 2 16:50 /<oracle home>/bin/oracle

The ASMdisks would be owned by grid:asmadmin so if the database needs to access those disks then the oracle binaries have to be oracle:asmadmin.

Change the group to asmadmin :

chown oracle:asmadmin oracle

chgrp asmadmin /<oracle home>/bin/oracle


 ls -lrt  /<oracle home>/bin/oracle


 -rwsr-s–x 1 oracle asmadmin 327811823 Oct 5 16:50 <oracle home>/bin/oracle

SET NEWNAME FOR DATAFILE

If this issue is not permission in your environment, then use SET NEWNAME command to specify path\location on the target server.

To solve this error, modify the restore DATAFILE command would be “SET NEWNAME FOR DATAFILE” followed by file number and the path where the file is to be restored.

To solve this error, use SET NEWNAME FOR DATAFILE command before restore database as follows

connect target /
run

allocate channel ch01 device type disk;
allocate channel ch02 device type disk;
allocate channel ch03 device type disk;
allocate channel ch04 device type disk;
