Disables the Oracle ASM proxy resource. Oracle ASM will restart if it contains Oracle Clusterware data or if the node restarts and it was running before the node failed. The srvctl disable asm command also prevents the srvctl start asm command from starting Oracle ASM instances.
Disabling the Oracle ASM proxy resource prevents the databases and disk groups from starting because they depend on the Oracle ASM proxy resource.
Note:
To manage Oracle ASM on Oracle Database 12c installations, use the SRVCTL binary in the Oracle Grid Infrastructure home for a cluster (Grid home). If you have Oracle RAC or Oracle Database installed, then you cannot use the SRVCTL binary in the database home to manage Oracle ASM.
Oracle ASM is part of the Oracle Clusterware stack and when OCR and voting files are stored on Oracle ASM, then Oracle ASM starts when OHASD starts the Oracle Clusterware stack. The srvctl disable asm command does not prevent the Oracle ASM instance managed by OHASD from starting. Oracle ASM, therefore, starts as needed by the Oracle Clusterware stack.
The srvctl disable asm command prevents the Oracle ASM Oracle Clusterware proxy resource, and any resources that depend on it, from starting. So, the command prevents Oracle Clusterware-managed objects, such as databases, disk groups, and file systems that depend on Oracle ASM, from starting. For example, the srvctl start database | diskgroup | filesystem command fails to start any of those objects on nodes where the Oracle ASM Oracle Clusterware proxy resource is disabled. The command also prevents the srvctl start asm command from starting Oracle ASM on remote nodes.
Use the srvctl disable asm command with the following syntax:
srvctl disable asm [-proxy] [-node node_name]
