Sun Cluster 3.0 Installation Guide

How to Perform Post-Installation Setup

Perform this procedure one time only, after the cluster is fully formed.

  1. Verify that all nodes have joined the cluster.

    1. From one node, display a list of cluster nodes to verify that all nodes have joined the cluster.

      You do not need to be logged in as superuser to run this command.


      % scstat -n
      

      Output resembles the following.


      -- Cluster Nodes --
                         Node name      Status
                         ---------      ------
        Cluster node:    phys-schost-1  Online
        Cluster node:    phys-schost-2  Online
    2. On each node, display a list of all the devices that the system checks to verify their connectivity to the cluster nodes.

      You do not need to be logged in as superuser to run this command.


      % scdidadm -L
      

      The list on each node should be the same. Output resembles the following.


      1       phys-schost-1:/dev/rdsk/c0t0d0 /dev/did/rdsk/d1
      2       phys-schost-1:/dev/rdsk/c1t1d0 /dev/did/rdsk/d2
      2       phys-schost-2:/dev/rdsk/c1t1d0 /dev/did/rdsk/d2
      3       phys-schost-1:/dev/rdsk/c1t2d0 /dev/did/rdsk/d3
      3       phys-schost-2:/dev/rdsk/c1t2d0 /dev/did/rdsk/d3
      ...
    3. Identify from the scdidadm output the global device ID (DID) name of each shared disk you will configure as a quorum device.

      For example, the output in the previous substep shows that global device d2 is shared by phys-schost-1 and phys-schost-2. You need this information in Step 4. Refer to "Quorum Devices" for further information about planning quorum devices.

  2. Become superuser on one node of the cluster.

  3. Start the scsetup(1M) utility.


    # scsetup
    

    The Initial Cluster Setup screen is displayed.


    Note -

    If the Main Menu is displayed instead, this procedure has already been successfully performed.


  4. Respond to the prompts.

    1. At the prompt Do you want to add any quorum disks?, configure at least one shared quorum device if your cluster is a two-node cluster.

      A two-node cluster remains in install mode until a shared quorum device is configured. After the scsetup utility configures the quorum device, the message Command completed successfully is displayed. If your cluster has three or more nodes, configuring a quorum device is optional.

    2. At the prompt Is it okay to reset "installmode"?, answer Yes.

      After the scsetup utility sets quorum configurations and vote counts for the cluster, the message Cluster initialization is complete is displayed and the utility returns you to the Main Menu.


    Note -

    If the quorum setup process is interrupted or fails to complete successfully, rerun Step 3 and Step 4.


  5. From any node, verify that cluster install mode is disabled.


    # scconf -p | grep 'Cluster install mode:'
    Cluster install mode:                                  disabled
