Sun Cluster 3.1 Software Installation Guide

How to Perform Post-Installation Setup

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

Verify that all nodes have joined the cluster.

  1. From one node, verify that all nodes have joined the cluster.

    Run the scstat(1M) command to display a list of the cluster nodes. 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, verify device connectivity to the cluster nodes.

    Run the scdidadm(1M) command to display a list of all the devices that the system checks. 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. Determine the global device ID (DID) of each shared disk you will configure as a quorum device.

    Use the scdidadm output from Step 2 to identify the 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 will use this information in Step 8. See Quorum Devices for further information about planning quorum devices.

  4. Are you adding a new node to an existing cluster?

  5. Did you use SunPlex Manager to install Sun Cluster software?

    • If yes, skip to Step 11. During Sun Cluster installation, SunPlex Manager assigns quorum votes and removes the cluster from install mode for you.

    • If no, go to Step 6.

  6. Become superuser on one node of the cluster.

  7. Start the scsetup(1M) utility.


    # scsetup

    The Initial Cluster Setup screen is displayed.

    Note –

    If the Main Menu is displayed instead, initial cluster setup was already successfully performed. Skip to Step 11.

    If the quorum setup process is interrupted or fails to complete successfully, rerun scsetup.

  8. 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, quorum device configuration is optional.

  9. 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.

  10. From any node, verify the device and node quorum configurations.


    % scstat -q

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

    You do not need to be superuser to run this command.


    % scconf -p | grep "Cluster install mode:"
Cluster install mode:                                  disabled

  12. Install volume management software.
