Hi All

This is neto from Brazil

How are you?

IMHO the issue is:

--[ INFO] PLAT-00010: Creating mapping from disk "/dev/sdb1" to raw device "/dev/raw/raw10".

Based on it, you have mounted sdb1 to raw10 and worked.

--[ INFO] ASM-00000: Mounting ASM Disk Group DG1_20100513162059538_1 on host dell67.

--[ERROR] FLOW-11019: Failure in ExecuteConnectionSteps: ORACLE-10003: Error executing SQL "ALTER DISKGROUP DG1_20100513162059538_1 MOUNT" against Oracle database +ASM: ORA-15032: not all alterations performed

ORA-15024: discovered duplicately numbered ASM disk 0

Seems to me that ASM instance doesn't have configure the ASM disktring and ASM is trying to discover all disks and ASM could be discovering two disks with same id (sdb1 and raw10).

You could try to use the following on ASM configuration: (ASM disk string)

Add:

/dev/raw/, /opt/NetApp/mount/

Please let me know the results

All the best
