Preparing Shared Storage 25

Installing and Configuring ASMlib

Use

oracle.com/technetwork/server-storage/linux/downloads/rhel5-

084877.html

to download the following files:

• oracleasm-support

• oracleasmlib

•

oracleasm

NOTE: If your current OS distribution is Oracle Linux, you can obtain the

software from the Unbreakable Linux Network using ULN.

NOTE: Download the latest versions of oracleasm-support and oracleasmlib

but the version of oracleasm must match the current kernel used in your

system. Check this information issuing the command

uname -r.

Enter the following command as

root

rpm -Uvh oracleasm-support-* \

oracleasmlib-* \

oracleasm-$(uname -r)-*

NOTE: Replace * by the correct version numbers of the packages or you can

leave them in place of the command ensuring that there are no multiple

versions of the packages in the shell's current working directory.

Using ASMLib to Mark the Shared Disks as Candidate Disks

To configure ASM use the init script that comes with the oracleasm-

support package. The recommended method is to run the following

command as root:

# /usr/sbin/oracleasm configure -i

NOTE: Oracle recommends using the oracleasm command found under

/usr/sbin. The /etc/init.d path has not been deprecated, but the oracleasm

binary provided by Oracle in this path is used for internal purposes.
