ABORT

Clause
The Oracle ASM instance immediately shuts down without the orderly dismount of disk groups. This causes recovery to occur upon the next Oracle ASM startup.

If any database instance is connected to the Oracle ASM instance, then the database instance aborts.

If any Oracle Automatic Storage Management Cluster File System (Oracle ACFS) file systems
are currently mounted on Oracle ADVM volumes, those file systems should first be dismounted. Otherwise, applications encounter I/O errors and Oracle ACFS user data and metadata may not be written to storage before the Oracle ASM storage is fenced.
