Installing and Configuring Oracle ASMLIB Software

Review this information to install and configure the Oracle Automatic Storage Management library driver software manually.

Oracle ASMLIB is included with the Oracle Linux packages, and with SUSE Linux Enterprise Server. If you are a member of the Unbreakable Linux Network, then you can install the Oracle ASMLIB RPMs by subscribing to the Oracle Linux channel, and using yum to retrieve the most current package for your system and kernel. For additional information, see the following URL:

http://www.oracle.com/technetwork/topics/linux/asmlib/index-101839.html

Note:

• You must install Oracle ASMLib v3 (oracleasmlib-3.0.0 or later and oracleasm-support-3.0.0 or later) on all Oracle Database servers with Oracle Linux 8 and later kernels.
• You must install Oracle ASMLib v2 (oracleasmlib-2.0.17 or later and oracleasm-support-2.1.3 or later) on all Oracle Database servers with Oracle Linux 7 and earlier kernels
• You can also use dnf instead of yum. For more information, see Comparing Yum Version with DNF

1. Enter the following command to determine the kernel version and architecture of the system:

   # uname -rm
   

2. Depending on your operating system version, download the required Oracle Automatic Storage Management library driver packages and driver:

   http://www.oracle.com/technetwork/server-storage/linux/asmlib/index-101839.html

   See Also:

   My Oracle Support note 1089399.1 for information about Oracle ASMLIB support with Red Hat distributions:

   https://support.oracle.com/rs?type=doc&id=1089399.1

3. Switch to the root user:

   $ su -

4. Depending on your operating system, you must install the oracleasmlib and oracleasm-support packages for all Oracle ASMLIB installations.

   Note:

   Oracle Unbreakable Enterprise Kernel includes driver module, so you do not need to install kmod-oracleasm.

   Method 1 (recommended): If you have subscribed to Unbreakable Linux Network (ULN), then you can install the Oracle Automatic Storage Management library driver packages using a single yum command.

   For Unbreakable Enterprise Kernel

   # yum install oracleasm-support
   # yum install oracleasmlib
   # yum install libbpf
   # yum install libbpf-devel

   For Red Hat Compatible Kernel

   # yum install oracleasm-support
   # yum install oracleasmlib

   Method 2: Alternatively, download the Oracle Automatic Storage Management library driver packages as described in Step 2 and run the following rpm -ivh commands to install the packages in sequence.

   For Unbreakable Enterprise Kernel

   # rpm -ivh oracleasm-support-version.arch.rpm
   # rpm -ivh oracleasmlib-version.arch.rpm
   # rpm -ivh libbpf-version.arch.rpm
   # rpm -ivh libbpf-devel-version.arch.rpm

   For Red Hat Compatible Kernel

   # rpm -ivh oracleasm-support-version.arch.rpm
   # rpm -ivh oracleasmlib-version.arch.rpm

   Where version is the version of the Oracle Automatic Storage Management library driver, arch is the system architecture, and kernel is the version of the kernel that you are using.

   For example, if you are using Oracle Linux 9 on an x86_64 system, then enter a command similar to the following:

   # rpm -ivh oracleasmlib-3.0.0-9.el9.x86_64 \
              oracleasm-support-3.0.0-21.el9.x86_64

5. For SUSE Linux Enterprise Server 15, install the latest oracleasmlib and oracleasm-support RPM from:
   https://www.oracle.com/linux/downloads/linux-asmlib-sles15-downloads.html

   Note:

   ASMLib v3 is not supported for SUSE Linux Enterprise Server.

   Install the latest oracleasm driver module from the refreshed SUSE Linux Enterprise Server repository. The package name is oracleasm-kmp-default. For example, oracleasm-kmp-default-2.0.8_k5.14.21_150500.55.36-150500.7.3.1.x86_64

6. Enter the following command to run the oracleasm initialization script with the configure option:

   # /usr/sbin/oracleasm configure -i 

   Note:

   The oracleasm command in /usr/sbin is the command you should use. The /etc/init.d path is not deprecated, but the oracleasm binary in that path is now used typically for internal commands.
7. Enter the following information in response to the prompts that the script displays:

   Prompt	Suggested Response
   Default user to own the driver interface:	Standard groups and users configuration: Specify the Oracle software owner user (for example, oracle) Job role separation groups and users configuration: Specify the Grid Infrastructure software owner (for example, grid)
   Default group to own the driver interface:	Standard groups and users configuration: Specify the OSDBA group for the database (for example, dba). Job role separation groups and users configuration: Specify the OSASM group for storage administration (for example, asmadmin).
   Start Oracle ASM Library driver on boot (y/n):	Enter y to start the Oracle Automatic Storage Management library driver when the system starts.
   Scan for Oracle ASM disks on boot (y/n)	Enter y to scan for Oracle ASM disks when the system starts.

   The script completes the following tasks:

   • Creates the /etc/sysconfig/oracleasm configuration file

   • Mounts the ASMLIB driver file system

     Note:

     The Oracle ASMLIB file system is not a regular file system. It is used only by the Oracle ASM library to communicate with the Oracle ASMLIB.
8. Enter the following command to enable the Oracle ASMLIB file system:
   # systemctl enable oracleasm
9. Enter the following command to start the Oracle ASMLIB file system:
   # systemctl start oracleasm
