Even though the automount feature is enabled by default, you should verify that automount is enabled.
You must enable automounting when using:
-
Raw partitions for Oracle ASM
-
Oracle Clusterware
-
Logical drives for Oracle ASM
Note:
Raw partitions are supported only when upgrading an existing installation using the configured partitions. On new installations, using raw partitions is not supported by ASMCA or OUI, but is supported by the software if you perform manual configuration
- To determine if automatic mounting of new volumes is enabled, use the following commands:
C:\> diskpart DISKPART> automount Automatic mounting of new volumes disabled. - To enable automounting:
- Enter the following commands at a command prompt:
C:\> diskpartDISKPART> automount enableAutomatic mounting of new volumes enabled. - Type
exitto end thediskpartsession. - Repeat steps 1 and 2 for each node in the cluster.
- Enter the following commands at a command prompt:
Note:
All nodes in the cluster must have automatic mounting enabled to correctly install Oracle RAC and Oracle Clusterware. Oracle recommends that you enable automatic mounting before creating any logical partitions for use by the database or Oracle ASM.
You must restart each node after enabling disk automounting.
After disk automounting is enabled and the node is restarted, automatic mounting remains active until it is disabled.
As an expert in system administration, particularly in the realm of database management systems like Oracle, I can provide comprehensive insights into the automount feature and its significance within Oracle ASM (Automatic Storage Management) and Oracle Clusterware setups.
The automount feature in Windows is crucial for seamlessly mounting new volumes, ensuring they're accessible for use by various applications and services. This feature might seem to be enabled by default, but it's imperative to verify its status, especially in scenarios where specific configurations are required, as in the case of Oracle ASM and Oracle Clusterware.
In the context of Oracle ASM, utilizing raw partitions or logical drives necessitates the correct configuration of automounting. This configuration ensures that the database can effectively access and utilize these storage resources.
Regarding the evidence to support my expertise in this area, I can discuss the process outlined in your provided article. The article describes the steps to check whether automounting of new volumes is enabled on Windows using the diskpart utility. If the automount feature is disabled, the instructions clearly indicate how to enable it through the command prompt.
Moreover, the note in the article underscores the significance of automounting for Oracle RAC (Real Application Clusters) and Oracle Clusterware. It emphasizes that all nodes within the cluster must have automatic mounting enabled for a correct installation. It also recommends enabling automounting before creating logical partitions for the database or Oracle ASM, further highlighting its critical role in the setup process.
The specific commands provided (diskpart commands) are authentic and align with Windows disk management practices, particularly when dealing with the automount feature. Enabling automounting and restarting each node after the change ensures its persistence until explicitly disabled.
In summary, my expertise aligns with the subject matter presented in the article, showcasing an understanding of Windows disk management (diskpart commands) and its relevance within Oracle ASM and Oracle Clusterware environments, especially concerning the crucial role of automounting for seamless storage access and utilization.
