FSPM and Clustering Overview

Oracle FS Path Manager (FSPM) can be used in a cluster environment. Refer to the operating system for information on cluster requirements and support. Additional information to support FSPM in a cluster environment is presented here.

For all operating systems, FSPM must be installed before you set up clustering. Once FSPM is installed, then set up clustering to avoid configuration errors.

For Red Hat, the Cluster Logical Volume Manager (CLVM) associated with the shared storage unit and the Red Hat Global File System are both required to prevent failed nodes from accessing shared devices.

For more information on how to set up clustering in your environment using Red Hat, refer to the RHEL documentation (http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Cluster_Suite_Overview/index.html) or documentation (http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Cluster_Administration/index.html)

Note: For Red hat, the Red Hat Cluster Suite installs and enables the scsi_reserve service by default. This service should be disabled if the scsi_fence option is not used as a fencing mechanism. To disable the scsi_reserve service, run the following command:

# chkconfig scsi_reserve off

For Oracle Linux, to obtain additional information on how to set up clustering in your environment, refer to the Oracle Real Application Clusters (RAC) documentation (http://www.oracle.com/technetwork/database/clustering/overview/index-086583.html).

For Oracle Linux, the Oracle Clusterware associated with the shared storage unit and the Oracle Clustering File System (OCFS) are both required to prevent failed nodes from accessing shared devices.

For SLES 11, refer to the SUSE Linux Enterprise High Availability Extension Guide( https://www.suse.com/documentation/sle_ha/singlehtml/book_sleha/book_sleha.html) for instructions.
