WARNING: Before you begin any of the procedures in this section, read the
safety information that shipped with your system. For additional best practices
information, see the Dell Regulatory Compliance website at

Oracle Real Application Clusters (RAC) is a complex database configuration
that requires an ordered list of procedures. The following sections describe
how to verify, adjust and configure the storage disks for the Fibre Channel,
direct-attached SAS, or iSCSI storage on your host.
Verifying and Identifying Your Storage Disks
While configuring the clusters, create partitions on your Fibre Channel,
direct-attached SAS, or iSCSI storage system. To create the partitions, all the
nodes must detect the external storage devices.
NOTE: The procedure in this section describes how to deploy the Oracle database
for direct-attached SAS storage as well as for Fibre Channel storage. For illustration
purposes, Fibre Channel storage nomenclature is used. If direct-attached SAS or
iSCSI storage (Dell PowerVault MD3000, MD3000i, MD32xx, MD32xxi, or Dell
EqualLogic storage array) is used, see
Table 7-1 to translate Fibre Channel
nomenclature to PowerVault MD3000, MD3000i or Dell EqualLogic nomenclature.
