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

Oracle Clusterware and Oracle Solaris Cluster need to interoperate between each other to ensure that dependencies between various file systems, global devices, or Oracle ASM disk groups are met. To achieve this, you create sun-prefixed Oracle Clusterware resources. Once created, the sun-prefixed Oracle Clusterware resources ensure an orderly startup of an Oracle ASM disk group and the Oracle RAC 10g release 2 or 11g release 1 database.

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 ASM disk-group resource for Oracle Clusterware.

   # Grid_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 ASM disk-group resource for Oracle Clusterware.

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

   # Grid_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 ASM disk-group resource for Oracle Clusterware 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 ASM disk-group resource for Oracle Clusterware that you registered in Step 4.

   # Grid_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 ASM disk-group resource for Oracle Clusterware.

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

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

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

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

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

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

      # Grid_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 ASM instance resource for Oracle Clusterware.

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

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

      # Grid_home/bin/crs_stat -p | grep -i asm | grep node

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

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