How to Create an Oracle Clusterware Oracle ASM Resource for Interoperation With Sun Cluster Software

Depending on your configuration, some Oracle components that are represented as Oracle ASM resources might depend on file systems and global devices that Oracle Solaris Cluster manages. Create an Oracle Clusterware Oracle ASM resource for each Oracle Solaris Cluster resource for scalable device groups and scalable file-system mount points on which Oracle components depend. The Oracle Clusterware Oracle ASM resources that you create track the status of their associated Oracle Solaris Cluster resources. The Oracle Clusterware Oracle ASM resources also ensure the orderly startup of Oracle Clusterware Oracle ASM resources.

1. Become superuser.
2. On each node where Support for Oracle RAC is to run, create the /var/cluster/ucmm/profile directory, if it does not already exist.

   # mkdir -p /var/cluster/ucmm/profile

   Profiles for Oracle Clusterware resources are created in this directory.

3. Create a profile for the Oracle Clusterware Oracle ASM disk-group resource.

   # crs-home/bin/crs_profile \
   -create sun.node.asm-dg-rs \
   -t application -d "description" \
   -dir /var/cluster/ucmm/profile \
   -a /opt/SUNWscor/dsconfig/bin/scproxy_crs_action \
   -p restricted -h node -f -o ra=60,st=20

   asm-dg-rs

   Specifies the name of the Oracle Clusterware Oracle ASM disk-group resource.

4. Register the Oracle Clusterware Oracle ASM disk-group resource for which you created a profile in Step 3.

   # crs-home/bin/crs_register sun.node.asm-dg-rs \
   -dir /var/cluster/ucmm/profile

5. Ensure that the Oracle Solaris Cluster resource, for which the Oracle Clusterware Oracle ASM disk-group resource is a proxy, is online.
   1. Obtain the state of the Oracle Solaris Cluster resource.

      # clresource status asm-dg-rs

   2. If the state of the Oracle Solaris Cluster resource is not online, bring online the resource group that contains the Oracle Solaris Cluster resource.

      If the state of the Oracle Solaris Cluster resource is online, omit this step.

      # clresourcegroup online -emM asm-dg-rg

6. Start the Oracle Clusterware Oracle ASM disk-group resource that you registered in Step 4.

   # crs-home/bin/crs_start sun.node.asm-dg-rs

7. On each node where Support for Oracle RAC is to run, add a dependency for the Oracle Clusterware Oracle ASM disk-group resource.

   Add the Oracle Clusterware Oracle ASM disk-group resource that you registered in Step 4 to the list of resources that the dependent Oracle Clusterware Oracle ASM disk-group resource requires.

   1. Obtain the name of the Oracle Clusterware RAC instance resource.

      # crs-home/bin/srvctl config database -d db-name | grep node

   2. List the dependencies for the Oracle Clusterware RAC instance resource.

      # crs-home/bin/crs_stat -p ora.db-name.instance.inst | grep REQUIRED_RESOURCES

   3. Add the name of the Oracle Clusterware Oracle ASM disk-group resource to the list that you obtained in Step b.

      # crs-home/bin/crs_register ora.db-name.instance.inst \
      -update -r "existing-list sun.node.asm-dg-rs"

8. On each node where Support for Oracle RAC is to run, add a dependency for the Oracle Clusterware Oracle ASM instance resource.

   Add the Oracle Clusterware Oracle ASM instance resource as a depended-on resource that the Oracle Clusterware Oracle ASM disk group requires.

   1. Obtain the name for the Oracle Clusterware Oracle ASM instance resource.

      # crs-home/bin/crs_stat -p | grep -i asm | grep node

   2. Add the Oracle Clusterware Oracle ASM instance resource as a depended-on resource to the Oracle Clusterware Oracle ASM disk-group resource.

      # crs-home/bin/crs_register -p sun.node.asm-dg-rs 
      -update -r crs-asm-instance
