PROBLEM:

While mounting a diskgroup in restrict mode, got below error:

 

SQL> alter diskgroup NEWTST mount restricted;
alter diskgroup NEWTST mount restricted
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15235: diskgroup NEWTST mount mode conflicts with existing mount

 

Solution:

This is because, the diskgroup is dismounted in local node, but it is in mount stage is remote nodes.

 

 

So to mount an asm diskgroup in restrict mode, Make sure the diskgroup is dismounted on all remote nodes.

 

NODE 2 :

 

Now connect to NODE 1  and run the restrict command.
