RedHat(RHEL)6 support ASMLIB (RHEL6支持asmlib)

With the annoucement of Oracle’s database support on RHEL6 and OEL6, they have decided to stop making ASMLIB for RHEL compatible kernels. ASMLIB is now only available if you are using Oracle Unbreakable Linux Kernel. RHEL6 has also deprecated the use of setting LUN permissions using multipath.conf therefore we have to fall back to UDEV rules.

Recent events enabled Red Hat and Oracle to work together, and Oracle is now officially supporting ASMlib on Red Hat Enterprise Linux 6.4 and newer.

ORACLE sound:

All ASMLib installations require that the ‘kmod-oracleasm’,'oracleasmlib’ and ‘oracleasm-support’ packages be installed on the system. The ‘oracleasmlib’ and ‘oracleasm-support’ packages are available for download at the locations listed below.

The kernel driver package ‘kmod-oracleasm’ is available directly from Red Hat, and can be installed from the “RHEL Server Supplementary (v. 6 64-bit x86_64)” channel on Red Hat Network (RHN). Use the ASMLib kernel driver that corresponds to the version of the Red Hat Enterprise Linux kernel you’re running.

To identify which version of the ASMLib kernel driver you need, view the description field of the ‘kmod-oracleasm’ package in the “RHEL Server Supplementary (v. 6 64-bit x86_64)” channel on RHN.

Redhat Sound:

Oracle ASMLib availability and support. Kernel module kmod-oracleasm package is now available for Red Hat Enterprise Linux 6.

Oracle ASM (Automated Storage Management) is a data volume manager for Oracle databases. ASMLib is an optional utility that can be used on Linux systems to manage Oracle ASM devices. ASMLib consists of the following components:
- kmod-oracleasm (open-source (GPL) kernel module package)
- oracleasm-support (open-source (GPL) utitilies package)
- oracleasmlib (proprietary library package)

The ASMLib kernel module package is provided for the convenience of our customers but is not supported,

Please note that Red Hat is continuing to develop fully open-source alternatives to ASMLib. Red Hat has provided a reference architecture for Oracle RAC clusters using upstream-accepted technologies such as dm-multipath and udev.
