ORA-15072: command requires at least 2 regular failure groups, discovered only 1

Hi,

 

I'm trying to create a diskgroup for a temporary purpose. I didnt mention the type of redundancy. When i ran the below command i got the mentioned errors.

SQL> Create diskgroup temp_dg disk '/dev/mapper/003w1_e2p5' attribute 'compatible.asm' = '11.2.0.0.0';

Create diskgroup temp_dg disk '/dev/mapper/003w1_e2p5' attribute 'compatible.asm' = '11.2.0.0.0'

*

ERROR at line 1:

ORA-15018: diskgroup cannot be created

ORA-15072: command requires at least 2 regular failure groups, discovered only 1

 

When i used two disks, then diskgroup got created.

 

All the diskgroups in ASM are of EXTERNAL redundancy.

 

 

SQL> Select distinct type from v$asm_diskgroup;

 

 

TYPE

------

EXTERN

 

I would like to know why it was asking to create diskgroup of NORMAL redundancy. Is there some thing like default REDUNDANCY in ASM.

 

Please share your views.
