2. When tried to add ORCLDISKASM1040 to existing ASm disk group following error is seen

---

SQL> ALTER DISKGROUP disk_group_1 ADD DISK ‘\.ORCLDISKASM1040’;

ALTER DISKGROUP disk_group_1 ADD DISK ‘\.ORCLDISKASM1040’

*

ERROR at line 1:

ORA-15032: not all alterations performed

ORA-15031: disk specification ‘\.ORCLDISKASM1040’ matches no disks

Please help/suggest on how to fix this………………………………

Anu,

1. Does the disk appear under v$asm_disk?

You can check it as:

select group_number, name, path from v$asm_disk;

2. Is this a new LUN created?

3. Have you used asmtoolg to delete any existing lun ?

If asmtoolg was used to delete any existing lun then it is mandatory to bounce the ASM instance and then try to add a lun from scratch.
