1. All nodes as Root
RPM-IVH oracleasmlib-2.0.4-1.el6.x86_64.rpm
Rpm-qa *asm*kmod-oracleasm-2.0.8-13.0.1.el6_8.x86_64oracleasm-support-2.1.8-1.el6.x86_ 64oracleasmlib-2.0.4-1.el6.x86_64

2. After loading the required RPM, you can start configuring Asmlib.
Configure Asmlib by running the following on all nodes:
Sudo/etc/init.d/oracleasm Configure
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
Initializing the Oracle asmlib driver: [OK]
Scanning the system for Oracle asmlib disks: [OK]
3.Modify ASM config file (root) all nodes (Alredy do by Linux team) – Validate this.
[Email protected] ~]$ cat/etc/sysconfig/oracleasm-_dev_oracleasm
Oracleasm_enabled=true
Oracleasm_uid=oracle
Oracleasm_gid=dba
Oracleasm_scanboot=true
Oracleasm_scanorder= "DM"
Oracleasm_scanexclude= "SD"
Oracleasm_use_logical_block_size=false
4. Restart the Asmlib service
Sudo/etc/init.d/oracleasm stop
Sudo/etc/init.d/oracleasm start
5.create Disk:

Use the Asmlib Createdisk to build a candidate disk that can be used by ASM
Sudo/usr/sbin/oracleasm Createdisk OCR_VTE01/DEV/MAPPER/MPATHL
Sudo/usr/sbin/oracleasm Createdisk Ocr_vte02/dev/mapper/mpathn
Sudo/usr/sbin/oracleasm Createdisk Ocr_vte03/dev/mapper/mpathm
Sudo/usr/sbin/oracleasm Createdisk dsk01/dev/mapper/mpathe
Sudo/usr/sbin/oracleasm Createdisk DSK02/DEV/MAPPER/MPATHF
Sudo/usr/sbin/oracleasm Createdisk DSK03/DEV/MAPPER/MPATHG
Sudo/usr/sbin/oracleasm Createdisk Dsk04/dev/mapper/mpathh
Sudo/usr/sbin/oracleasm Createdisk Dsk05/dev/mapper/mpathi
Sudo/usr/sbin/oracleasm Createdisk DSK06/DEV/MAPPER/MPATHJ
Sudo/usr/sbin/oracleasm Createdisk DSK07/DEV/MAPPER/MPATHK
Sudo/usr/sbin/oracleasm Listdisks
Sudo/usr/sbin/oracleasm-discover
Run the below on other nodes:
Sudo/usr/sbin/oracleasm Scandisks
Sudo/usr/sbin/oracleasm Listdisks
Sudo/usr/sbin/oracleasm-discover
About the pre-preparatory work to do here is similar, next time is to start the cluster installation.
This section is mainly about the installation configuration of the Asmlib and the use of the disks needed to make the disks available to ASM.
