Recreation of controlfile fail

Question

Hi all,
I am attempting to recreate the controlfile for a 2 node RAC (10g) on EL4.I am using ASM for the shared storage. I copied the relevant section from the ASCII backup controlfile, when I run the script I am getting the following errors:
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-12720: operation requires database is in EXCLUSIVE mode
.

Answer 1

Thanks for the reply.
Yes I lost a diskgroup that contained the controlfile.
I must also share that the shared file system was NFS before I migrated it to ASM. I took a backup after I migrated to ASM.
When I restored the DB it restored the datafiles to the previous NFS location ( Could this be because DB_CREATE_FILE_DEST is set to '/share1/oradata' in the spfile?), I therefore had to change the path to the datafiles from '+DG1/devdb/datafile/' to the NFS location as seen in the ascii file.
The ASCII is as follows
