ORA-15260 resolution when Oracle 11g ASM increases Disk

In Oracle 11g, add a disk to an existing disk group. The operation command is "alter diskgroup webdg add disk '/dev/raw/raw4 ';", however, if you use sysdba for connection, an error is returned.

ORA-15260: permission denied on ASM disk group
Inform the permission to be rejected.
