ProcedureHow to Upgrade Sun Cluster HA for DHCP

As a result of bug fixes, the configuration for IPMP based clusters has changed. If you are running Sun Cluster HA for DHCP on an IPMP-based cluster, you have to disable, delete and reregister the DHCP resource.

Steps
  1. Save the Sun Cluster DHCP resource definitions.


    # scrgadm -pvv -j resource > file1
    
  2. Disable the Sun Cluster DHCP resource.


    # scswitch -n -j resource
    
  3. Remove the Sun Cluster DHCP resource.


    # scrgadm -r -j resource
    
  4. Configure and register the Sun Cluster DHCP resource.

    1. Go to the directory that contains the dhcp_config file and the dhcp_register file.


      # cd /opt/SUNWscdhc/util
      
    2. Edit the dhcp_config file.


      # vi dhcp_config
      
    3. Run the dhcp_register file.


      # ./dhcp_register
      
  5. Save the Sun Cluster DHCP resource definitions.


    # scrgadm -pvv -j resource > file2
    
  6. Compare the updated definitions to the definitions that you saved before you updated the resource.

    Comparing these definitions enables you to determine if any existing extension properties have changed, for example, time-out values.


    # diff file1 file2
    
  7. Amend any resource properties that were reset.


    # scrgadm -c -j resource -x|y resource
    
  8. Bring online the Sun Cluster DHCP resource.


    # scswitch -e -j resource
