tmp]# /usr/sbin/oracleasm configure -i
Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets (‘[]’). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done

 

Step 7

[tmp]# /usr/sbin/oracleasm init
Creating /dev/oracleasm mount point: /dev/oracleasm
Loading module “oracleasm”: oracleasm
Configuring “oracleasm” to use device physical block size
Mounting ASMlib driver filesystem: /dev/oracleasm

#

Step 8

[tmp]# systemctl enable oracleasm
Synchronizing state of oracleasm.service with SysV service script with /usr/lib/systemd/systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable oracleasm

#

Step 9

[ tmp]# systemctl start oracleasm
