原来非多路径的rac怎么更改为多路径

[Please set your asm_diskstring='ORCL:*'.

1) Log into ASM:

SQL> ALTER SYSTEM SET asm_diskstring='ORCL:*';

This init parameter can be dynamically changed.

2) Then, check the change was applied:
======================================================
SQL> show parameter ASM_DISKSTRING

SQL> select path from v$asm_disk;
======================================================
3) Please note: If using RAC, then restart the CRS (Bounce the Cluster on both nodes), after modifying the asm_diskstring.
