  - The following list describes the SHUTDOWN modes and the behavior of the Oracle ASM instance in each mode.
  
  - NORMAL Clause - Oracle ASM waits for any in-progress SQL to complete before performing an orderly dismount of all of the disk groups and shutting down the Oracle ASM instance.
  - Before the instance is shut down, Oracle ASM waits for all of the currently connected users to disconnect from the instance.
  - If any database instances are connected to the Oracle ASM instance, then the SHUTDOWN command returns an error and leaves the Oracle ASM instance running.
  - NORMAL is the default shutdown mode.
  
  - IMMEDIATE or TRANSACTIONAL Clause - Oracle ASM waits for any in-progress SQL to complete before performing an orderly dismount of all of the disk groups and shutting down the Oracle ASM instance.
  - Oracle ASM does not wait for users currently connected to the instance to disconnect.
  - If any database instances are connected to the Oracle ASM instance, then the SHUTDOWN command returns an error and leaves the Oracle ASM instance running.
  - Because the Oracle ASM instance does not contain any transactions, the TRANSACTIONAL mode behaves the same as IMMEDIATE mode.
  
  - 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.
