Sun Cluster 2.2 System Administration Guide

Adding Sun Cluster Data Services

You can add a data service to an existing cluster by running the scinstall(1M) command. See Chapter 3 in the Sun Cluster 2.2 Software Installation Guide for details.

To add a data service to a two-node cluster with shared CCD, additional steps apply. Use the following procedure to add a data service to such a cluster.

How to Add a Data Service to a Two-Node Cluster With Shared CCD

  1. Unshare the shared CCD.

    You must reconfigure the cluster to unshare the CCD before you add any new data services. Run the following command on both nodes, as root, while both nodes are in the cluster: 


    phys-hahost1# /opt/SUNWcluster/bin/scconf clustername -S none
phys-hahost2# /opt/SUNWcluster/bin/scconf clustername -S none

    Note -

    You must unshare the CCD. If you attempt to add a data service while the CCD is in shared state, only the local ccd.database file will be updated, and not the shared CCD file. This attempt will cause registration of the new data service to fail.

  2. Add the new data services, using the following commands.

    Run all commands as root. In these examples, the node names are phys-hahost1 and phys-hahost2.

    1. Stop the cluster on the first node. 


      phys-hahost1# scadmin stopnode

    2. Use scinstall(1M) to add the new data service package to the first node.

      See Chapter 3 of the Sun Cluster 2.2 Software Installation Guide for details. This step automatically updates the local CCD file. 


      phys-hahost1# scinstall

    3. Stop the cluster on the second node.

      Note -

      The existing data services will be unavailable to clients after you stop the cluster on the second node and until you restart the cluster on the first node.


      phys-hahost2# scadmin stopnode

    4. Restart the cluster on the first node.


      phys-hahost2# scadmin startcluster phys-hahost1 clustername

    5. Use scinstall(1M) to add the new data service package to the second node. See Chapter 3 of the Sun Cluster 2.2 Software Installation Guide for details. This step automatically updates the local CCD file. 


      phys-hahost2# scinstall

    6. Add the second node to the cluster.


      phys-hahost2# scadmin startnode

  3. Reinstate the shared CCD.

    Run the scconf(1M) command on both nodes, as root. See the scconf(1M) man page for details. 


    phys-hahost1# /opt/SUNWcluster/bin/scconf clustername -S ccdvol
phys-hahost2# /opt/SUNWcluster/bin/scconf clustername -S ccdvol

    Then run the confccdssa(1M) command on one node only, as root. See the confccdssa(1M) man page for details. 


    phys-hahost1# /opt/SUNWcluster/bin/confccdssa
