Guidelines for Migrating from Legacy CFS Package to Modular CFS Package

•You must migrate the legacy CFS packages to modular CFS package only when the package is offline.

•It is recommended that all the disk groups and mount points used by an application in a package be consolidated into one single modular package so that the dependencies need not be configured explicitly in the configuration files. It is also recommended not to share the consolidated modular package between applications unless the applications are interdependent.

•A mount point in the consolidated modular package must have its disk groups in the same package and vice versa.

•It is not recommended to configure the storage belonging to different applications into one modular package.

•All the disk group and mount point packages that are consolidated into the modular package must be configured on the same set of nodes in the cluster.

•The storage checkpoint and snapshot packages cannot be merged with other general purpose disk group and mount point packages. It is recommended that all checkpoint and snapshot packages are merged into individual modular checkpoint and snapshot packages respectively. However, configuring diskgroups in snapshot packages is allowed to enable consolidation of storage required by snapshots in the same package.

•When you have Metrocluster for Oracle RAC clusters on different sites, the same package configuration must be present on all the sites for modular CFS packages. In other words, there should be an exact mirror copy of the package configuration on all the sites in a Metrocluster for Oracle RAC cluster environment.

Use Case Scenarios — Migrating Legacy CFS Packages to Modular CFS Packages

Use Case 1: Migration of application using two disk groups

Figure 37 depicts the legacy style of packaging where a separate package is created for each disk group and mount point in the cluster. The disk groups cvm_dg1 and cvm_dg2 are configured in the packages SG-CFS-DG1 and SG-CFS-DG2 respectively. The mount points /cfs1 and /cfs2 are configured on cvm_dg1/lvol1 and cvm_dg2/lvol2 in the packages SG-CFS-MP-1 and SG-CFS-MP-2 respectively.
