  8. Check the storage system controller module firmware revision. If necessary, install the most recent revision.

    For the firmware revision number and boot level, see the Sun StorEdge RAID Manager Release Notes. For the procedure about how to upgrade the firmware, see the Sun StorEdge RAID Manager User’s Guide.

  9. Set the Rdac parameters in the /etc/osa/rmparams file.


    Rdac_RetryCount=1
Rdac_NoAltOffline=TRUE

  10. Ensure that the controller module is set to active/active mode.

    For more information on controller modes, see the Sun StorEdge RAID Manager Installation and Support Guide and the Sun StorEdge RAID Manager User’s Guide.

  11. Set up the storage system controller module with logical unit numbers (LUNs) and hot spares.

    For the procedure about how to set up the storage system controller module with LUNs and hot spares, see the Sun StorEdge RAID Manager User’s Guide.

    Note –

    Use the format command to verify Solaris logical device names.

  12. Copy the /etc/raid/rdac_address file from the node on which you created the LUNs to the other node. If you copy this file to the other node, you ensure consistency across both nodes.

  13. Ensure that the new logical name for the LUN that you created in Step 11 appears in the /dev/rdsk directory on both nodes.
