How to Register and Configure the Scalable Device-Group Resource Group

Ensure that the Oracle ACFS file system is created. See How to Create an Oracle ACFS File System.

If you use Solaris Volume Manager for Sun Cluster, register and configure a scalable device-group resource group. Perform all steps from one node of the global cluster.

If your configuration does not use Solaris Volume Manager for Sun Cluster, do not perform this procedure. Proceed to How to Register and Configure the Oracle ASM Resource Group.

1. Assume the root role or become an administrator that provides solaris.cluster.admin and solaris.cluster.modify authorizations.
2. Create a scalable resource group to contain the scalable device-group resource.

   Set a strong positive affinity by the resource group for the multiple-owner volume-manager framework resource group.

   # clresourcegroup create -S \
   -p rg_affinities=++vucmm-fmwk-rg \
   -p rg_description="description"] \
   scal-dg-rg

3. Register the SUNW.ScalDeviceGroup resource type.

   # clresourcetype register SUNW.ScalDeviceGroup

4. Add an instance of the SUNW.ScalDeviceGroup resource type to the SUNW.ScalDeviceGroup resource group.

   Set a strong dependency for the instance of SUNW.ScalDeviceGroup on the svm-rs resource in the SUNW.vucmm_svm framework resource group. Limit the scope of this dependency to only the node where the SUNW.ScalDeviceGroup resource is running.

   # clresource create -t SUNW.ScalDeviceGroup -g scal-dg-rg \
   -p resource_dependencies=svm-rs{local_node} \
   -p diskgroupname=disk-group scal-dg-rs

5. Bring online and in a managed state the scalable device-group resource group.

   # clresourcegroup online -emM scal-dg-rg

6. Set an offline-restart dependency on crs-fmwk-rs by scal-dg-rs.

   # clresource set -p resource_dependency_offline_restart=scal-dg-rs crs-fmwk-rs
