deletedisk Unmark a disk device. Do not unmark a device that is currently in an ASM
disk group!
querydisk Determine if a specific disk is marked by the oracleasm driver.
listdisks List all disks attached to the server that are marked for use by oracleasm.
scandisks Identify disks marked for use by the cluster as oracleasm disks.
Software Installation
Whether you are creating a 2-node or a 16-node cluster, the procedure is the same; if you have
configured your servers as detailed in the previous sections, the installations you will perform
in the following sections will automatically push to each node you specify in the configuration
screens for Cluster Ready Services and the Oracle Database software itself.
Therefore, the following discussion is divided into three parts: CRS to prepare the clustering
environment, Oracle Database 11g software installation, and creating an instance of the database
on each node in the cluster. As I review each screen of each installation, I will provide background
and explanation as required so that you??™re prepared to make adjustments to your environment
once the installations are complete.
In many cases, the installation steps for the database software, the database itself, and ASM are
similar or identical to what you??™ve already seen in Chapters 1 and 4, and will find detailed in the
appendix. In the following sections, we??™ll focus on the differences you??™ll see for a RAC installation.
