Advm driver status of ASM in Oracle 11gR2

The ASM of Oracle 11G provides the features of volume groups and cluster file systems, and is fully compatible with the features similar to that of VxFS. Unlike the previous diskgroup, it truly has the ease of managing the file system. However, in order to continue the Storage Feature of the 10 GB disk group, we will continue to establish the database on the disk group at 11 GB.
Therefore, after 11gRAC is installed, the grid user logs on and uses the asmca tool to create a disk group.

On the ASMCA page displayed by the graphical tool, on the first tab, ASM instances found that the value of advm driver status is installed and loaded.
The instructions on the installation page clearly indicate the ASM Dynamic Volume Manager (ADVM) driver must be loaded on

All nodes of the cluster.

The following shows how to load the advm driver.

/U01/app/11.2.0/grid/network/admin @ serv1 => + ASM1 $ acfsdriverstate version
ACFS-9205: OS/ADVM, ACFS installed version = 2.6.18-8. el5 (x86_64)/090715.1

/Home/grid @ serv1 => + ASM1 $ ls-l/lib/modules/2.6.18-8. el5/extra/usm/

[Root @ serv1 bin] # cd/u01/app/11.2.0/grid/bin
[Root @ serv1 bin] #./acfsload start-s

Go back to the asmca tool interface and refresh it to find that the advm driver has been loaded.
