ProcedureTo Configure the Quorum Disk on a Two-Host Cluster

On a two-host cluster, if you chose no for Quorum Auto Configuration in the input_otp.dat file, you must manually select and configure the quorum disk as described in this procedure.


Note –

The following substeps apply only to a two-host cluster. If you are setting up a three-host or more clustered Sun OTP system, this procedure is optional.


  1. Open a separate terminal window and log in as root to the first Sun OTP host.

  2. Type the following command to display the cluster disk information.

    /usr/cluster/bin/cldev list -v


    DID Device                  Full Device Path
    d1                          pcl44-otp1:/dev/rdsk/c0t8d0
    d1                          pcl44-otp2:/dev/rdsk/c1t8d0
    d2                          pcl44-otp1:/dev/rdsk/c0t9d0
    d2                          pcl44-otp2:/dev/rdsk/c1t9d0
    d3                          pcl44-otp1:/dev/rdsk/c1t10d0
    d4                          pcl44-otp1:/dev/rdsk/c1t11d0
    d4                          pcl44-otp2:/dev/rdsk/c0t11d0
    d5                          pcl44-otp1:/dev/rdsk/c2t1d0
    d6                          pcl44-otp1:/dev/rdsk/c2t3d0
    d7                          pcl44-otp1:/dev/rdsk/c3t0d0
    d9                          pcl44-otp2:/dev/rdsk/c2t3d0
    d10                         pcl44-otp2:/dev/rdsk/c3t0d0

    In the above example, disks d1 and d2 are shared by both hosts of the two-host cluster. The quorum disk must be a shared disk.

  3. Configure a quorum disk.

    /usr/cluster/bin/clq add shared disk ID

    Where shared disk ID is a shared disk ID.

    For example, to configure d4 as a quorum disk, type the following command.

    /usr/cluster/bin/clq add d4

  4. Reset the two-host cluster to normal mode.

    /usr/cluster/bin/clq reset
